We're dividing 86902728 by 637 
We want to figure out the number of times 86902728 can be divided by 637.

Moving on to step 1:
If we divide 8 by 637, we get 0 and a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 637

Advancing to step 2:
When dividing 86 by 637, we get 0 with a remainder of 86.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 86, we end up with 86.
Bring next digit (9) of the dividend behind the 86 and repeat the process: 869 / 637

Going ahead to step 3:
The number 637 fits into 869 1 times, leaving a remainder of 232.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 637 from 869 and we're left with 232.
Include the next digit (0) from the dividend after 232, then repeat: 2320 / 637

Advancing to step 4:
When dividing 2320 by 637, we get 3 with a remainder of 409.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
Deduct 1911 from 2320 and we're left with 409.
Append the next digit (2) from the dividend to 409 and continue with: 4092 / 637

On to step 5:
4092 divided by 637 is 6 with a remainder of 270.
The number 6 becomes the next digit in our result. 
Result so far: 136.0
If we take 3822 away from 4092, we end up with 270.
Grab the next digit (7) from the dividend, add it to 270, then carry on: 2707 / 637

Going ahead to step 6:
The number 637 fits into 2707 4 times, leaving a remainder of 159.
The number 4 becomes the next digit in our result. 
Result so far: 1364.0
If we subtract 2548 from 2707, we get 159.
Grab the next digit (2) from the dividend, add it to 159, then carry on: 1592 / 637

Advancing to step 7:
The number 637 fits into 1592 2 times, leaving a remainder of 318.
Put 2 as the next digit of the answer. 
Result so far: 13642.0
Subtract 1274 from 1592 to get 318.
Grab the next digit (8) from the dividend, add it to 318, then carry on: 3188 / 637

Going ahead to step 8:
If we divide 3188 by 637, we get 5 and a remainder of 3.
Put 5 as the next digit of the answer. 
Result so far: 136425.0
Subtract 3185 from 3188 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 9:
The number 637 fits into 30 0 times, leaving a remainder of 30.
The next digit of our result is 0. 
Result so far: 136425.0
The remainder is 30 after subtracting 0 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 10:
The number 637 fits into 300 0 times, leaving a remainder of 300.
The number 0 becomes the next digit in our result. 
Result so far: 136425.0
Subtracting 0 from 300 leaves us with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

In conclusion, the division gives 136425.0 with a balance of 0.3.
