Let's divide 78920357 by 428
We want to figure out the number of times 78920357 can be divided by 428.

Let's proceed to step 1:
428 goes into 7 0 times with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 428

Going ahead to step 2:
The number 428 fits into 78 0 times, leaving a remainder of 78.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 78 after subtracting 0 from 78.
Grab the next digit (9) from the dividend, add it to 78, then carry on: 789 / 428

Going ahead to step 3:
If we divide 789 by 428, we get 1 and a remainder of 361.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 361 after subtracting 428 from 789.
Grab the next digit (2) from the dividend, add it to 361, then carry on: 3612 / 428

Going ahead to step 4:
The number 428 fits into 3612 8 times, leaving a remainder of 188.
Write down 8 as next digit of the result. 
Result so far: 18.0
Subtracting 3424 from 3612 leaves us with 188.
Append the next digit (0) from the dividend to 188 and continue with: 1880 / 428

On to step 5:
When dividing 1880 by 428, we get 4 with a remainder of 168.
Use 4 as the next digit of our solution. 
Result so far: 184.0
Subtracting 1712 from 1880 leaves us with 168.
Take the next digit (3) from the dividend and append it to 168, then repeat: 1683 / 428

Step 6:
If we divide 1683 by 428, we get 3 and a remainder of 399.
Put 3 as the next digit of the answer. 
Result so far: 1843.0
Subtract 1284 from 1683 to get 399.
Include the next digit (5) from the dividend after 399, then repeat: 3995 / 428

Let's proceed to step 7:
428 goes into 3995 9 times with a remainder of 143.
The number 9 becomes the next digit in our result. 
Result so far: 18439.0
If we subtract 3852 from 3995, we get 143.
Include the next digit (7) from the dividend after 143, then repeat: 1437 / 428

Advancing to step 8:
The number 428 fits into 1437 3 times, leaving a remainder of 153.
Put 3 as the next digit of the answer. 
Result so far: 184393.0
Subtracting 1284 from 1437 leaves us with 153.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1530, and continue the process.

Moving on to step 9:
428 can be fit into 1530 3 times, resulting in a remainder of 246.
The number 3 becomes the next digit in our result. 
Result so far: 184393.3
If we take 1284 away from 1530, we end up with 246.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2460, and continue the process.

Moving on to step 10:
2460 divided by 428 is 5 with a remainder of 320.
Write down 5 as next digit of the result. 
Result so far: 184393.35
If we take 2140 away from 2460, we end up with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Step 11:
When dividing 3200 by 428, we get 7 with a remainder of 204.
Record the quotient 7 as the next digit in the result. 
Result so far: 184393.357
The remainder is 204 after subtracting 2996 from 3200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

Moving on to step 12:
If we divide 2040 by 428, we get 4 and a remainder of 328.
The number 4 becomes the next digit in our result. 
Result so far: 184393.3574
Subtracting 1712 from 2040 leaves us with 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

Going ahead to step 13:
If we divide 3280 by 428, we get 7 and a remainder of 284.
The next digit of our result is 7. 
Result so far: 184393.35747
Subtract 2996 from 3280 to get 284.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

Step 14:
When dividing 2840 by 428, we get 6 with a remainder of 272.
Put 6 as the next digit of the answer. 
Result so far: 184393.357476
If we subtract 2568 from 2840, we get 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

Let's proceed to step 15:
2720 divided by 428 is 6 with a remainder of 152.
Write down 6 as next digit of the result. 
Result so far: 184393.3574766
Deduct 2568 from 2720 and we're left with 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Our division results in 184393.3574766 with a remaining 1.52e-06.
