We divide 78396361 by 570
We want to figure out the number of times 78396361 can be divided by 570.

Step 1:
7 divided by 570 is 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 570

Advancing to step 2:
570 can be fit into 78 0 times, resulting in a remainder of 78.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 78, we end up with 78.
Bring next digit (3) of the dividend behind the 78 and repeat the process: 783 / 570

Let's proceed to step 3:
783 divided by 570 is 1 with a remainder of 213.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 570 from 783 and we're left with 213.
Grab the next digit (9) from the dividend, add it to 213, then carry on: 2139 / 570

Step 4:
570 goes into 2139 3 times with a remainder of 429.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
If we take 1710 away from 2139, we end up with 429.
Bring next digit (6) of the dividend behind the 429 and repeat the process: 4296 / 570

Step 5:
The number 570 fits into 4296 7 times, leaving a remainder of 306.
The next digit of our result is 7. 
Result so far: 137.0
Deduct 3990 from 4296 and we're left with 306.
Include the next digit (3) from the dividend after 306, then repeat: 3063 / 570

Moving on to step 6:
570 can be fit into 3063 5 times, resulting in a remainder of 213.
Use 5 as the next digit of our solution. 
Result so far: 1375.0
The remainder is 213 after subtracting 2850 from 3063.
Take the next digit (6) from the dividend and append it to 213, then repeat: 2136 / 570

Going ahead to step 7:
When dividing 2136 by 570, we get 3 with a remainder of 426.
Write down 3 as next digit of the result. 
Result so far: 13753.0
Subtracting 1710 from 2136 leaves us with 426.
Bring next digit (1) of the dividend behind the 426 and repeat the process: 4261 / 570

Moving on to step 8:
The number 570 fits into 4261 7 times, leaving a remainder of 271.
Put 7 as the next digit of the answer. 
Result so far: 137537.0
If we take 3990 away from 4261, we end up with 271.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2710, and continue the process.

Step 9:
570 can be fit into 2710 4 times, resulting in a remainder of 430.
Put 4 as the next digit of the answer. 
Result so far: 137537.4
Subtracting 2280 from 2710 leaves us with 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

Going ahead to step 10:
570 goes into 4300 7 times with a remainder of 310.
Use 7 as the next digit of our solution. 
Result so far: 137537.47
The remainder is 310 after subtracting 3990 from 4300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Going ahead to step 11:
570 can be fit into 3100 5 times, resulting in a remainder of 250.
Write down 5 as next digit of the result. 
Result so far: 137537.475
If we take 2850 away from 3100, we end up with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Moving on to step 12:
570 can be fit into 2500 4 times, resulting in a remainder of 220.
Use 4 as the next digit of our solution. 
Result so far: 137537.4754
If we subtract 2280 from 2500, we get 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Going ahead to step 13:
570 can be fit into 2200 3 times, resulting in a remainder of 490.
Use 3 as the next digit of our solution. 
Result so far: 137537.47543
Subtract 1710 from 2200 to get 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

Moving on to step 14:
570 can be fit into 4900 8 times, resulting in a remainder of 340.
Record the quotient 8 as the next digit in the result. 
Result so far: 137537.475438
If we take 4560 away from 4900, we end up with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Let's proceed to step 15:
The number 570 fits into 3400 5 times, leaving a remainder of 550.
Write down 5 as next digit of the result. 
Result so far: 137537.4754385
Deduct 2850 from 3400 and we're left with 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5500, and continue the process.

Step 16:
If we divide 5500 by 570, we get 9 and a remainder of 370.
The next digit of our result is 9. 
Result so far: 137537.47543859
If we take 5130 away from 5500, we end up with 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

The quotient of the division is 137537.47543859, and the remainder is 3.7e-07.
