We look at the division of 77903707 by 570 
We want to divide 77903707 by 570.

On to step 1:
The number 570 fits into 7 0 times, leaving a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Include the next digit (7) from the dividend after 7, then repeat: 77 / 570

Let's proceed to step 2:
The number 570 fits into 77 0 times, leaving a remainder of 77.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 77, we end up with 77.
Take the next digit (9) from the dividend and append it to 77, then repeat: 779 / 570

Going ahead to step 3:
779 divided by 570 is 1 with a remainder of 209.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 570 from 779 to get 209.
Grab the next digit (0) from the dividend, add it to 209, then carry on: 2090 / 570

Moving on to step 4:
When dividing 2090 by 570, we get 3 with a remainder of 380.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
Deduct 1710 from 2090 and we're left with 380.
Bring next digit (3) of the dividend behind the 380 and repeat the process: 3803 / 570

Let's proceed to step 5:
The number 570 fits into 3803 6 times, leaving a remainder of 383.
Write down 6 as next digit of the result. 
Result so far: 136.0
If we subtract 3420 from 3803, we get 383.
Append the next digit (7) from the dividend to 383 and continue with: 3837 / 570

Let's proceed to step 6:
570 goes into 3837 6 times with a remainder of 417.
Write down 6 as next digit of the result. 
Result so far: 1366.0
Subtract 3420 from 3837 to get 417.
Grab the next digit (0) from the dividend, add it to 417, then carry on: 4170 / 570

Advancing to step 7:
The number 570 fits into 4170 7 times, leaving a remainder of 180.
Write down 7 as next digit of the result. 
Result so far: 13667.0
The remainder is 180 after subtracting 3990 from 4170.
Include the next digit (7) from the dividend after 180, then repeat: 1807 / 570

Moving on to step 8:
570 goes into 1807 3 times with a remainder of 97.
Put 3 as the next digit of the answer. 
Result so far: 136673.0
Deduct 1710 from 1807 and we're left with 97.
Since there are no more digits in the dividend, we add a zero to the remainder making it 970, and continue the process.

Going ahead to step 9:
When dividing 970 by 570, we get 1 with a remainder of 400.
Put 1 as the next digit of the answer. 
Result so far: 136673.1
Subtracting 570 from 970 leaves us with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Going ahead to step 10:
The number 570 fits into 4000 7 times, leaving a remainder of 10.
Record the quotient 7 as the next digit in the result. 
Result so far: 136673.17
The remainder is 10 after subtracting 3990 from 4000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 11:
570 can be fit into 100 0 times, resulting in a remainder of 100.
Write down 0 as next digit of the result. 
Result so far: 136673.17
The remainder is 100 after subtracting 0 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Let's proceed to step 12:
The number 570 fits into 1000 1 times, leaving a remainder of 430.
Record the quotient 1 as the next digit in the result. 
Result so far: 136673.1701
Deduct 570 from 1000 and we're left 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 13:
570 can be fit into 4300 7 times, resulting in a remainder of 310.
Use 7 as the next digit of our solution. 
Result so far: 136673.17017
Subtract 3990 from 4300 to get 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Step 14:
3100 divided by 570 is 5 with a remainder of 250.
The next digit of our result is 5. 
Result so far: 136673.170175
Subtracting 2850 from 3100 leaves us 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.

On to step 15:
570 can be fit into 2500 4 times, resulting in a remainder of 220.
Write down 4 as next digit of the result. 
Result so far: 136673.1701754
Subtract 2280 from 2500 to 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 16:
570 goes into 2200 3 times with a remainder of 490.
Use 3 as the next digit of our solution. 
Result so far: 136673.17017543
Subtracting 1710 from 2200 leaves us with 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

The final outcome is 136673.17017543, with a leftover of 4.9e-07.
