Let's divide 86711747 by 638
We want to divide 86711747 by 638.

Going ahead to step 1:
If we divide 8 by 638, we get 0 and a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 638

Step 2:
638 goes into 86 0 times with a remainder of 86.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 86 leaves us with 86.
Fetch the next digit (7) from the dividend, attach it to 86 and continue: 867 / 638

On to step 3:
867 divided by 638 is 1 with a remainder of 229.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 638 from 867 and we're left with 229.
Grab the next digit (1) from the dividend, add it to 229, then carry on: 2291 / 638

On to step 4:
638 can be fit into 2291 3 times, resulting in a remainder of 377.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
Subtracting 1914 from 2291 leaves us with 377.
Fetch the next digit (1) from the dividend, attach it to 377 and continue: 3771 / 638

Going ahead to step 5:
When dividing 3771 by 638, we get 5 with a remainder of 581.
Use 5 as the next digit of our solution. 
Result so far: 135.0
If we take 3190 away from 3771, we end up with 581.
Take the next digit (7) from the dividend and append it to 581, then repeat: 5817 / 638

On to step 6:
638 can be fit into 5817 9 times, resulting in a remainder of 75.
Record the quotient 9 as the next digit in the result. 
Result so far: 1359.0
If we subtract 5742 from 5817, we get 75.
Include the next digit (4) from the dividend after 75, then repeat: 754 / 638

On to step 7:
When dividing 754 by 638, we get 1 with a remainder of 116.
The next digit of our result is 1. 
Result so far: 13591.0
The remainder is 116 after subtracting 638 from 754.
Grab the next digit (7) from the dividend, add it to 116, then carry on: 1167 / 638

Going ahead to step 8:
The number 638 fits into 1167 1 times, leaving a remainder of 529.
The next digit of our result is 1. 
Result so far: 135911.0
Deduct 638 from 1167 and we're left with 529.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5290, and continue the process.

Advancing to step 9:
The number 638 fits into 5290 8 times, leaving a remainder of 186.
Put 8 as the next digit of the answer. 
Result so far: 135911.8
Subtract 5104 from 5290 to get 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

Let's proceed to step 10:
If we divide 1860 by 638, we get 2 and a remainder of 584.
The next digit of our result is 2. 
Result so far: 135911.82
If we take 1276 away from 1860, we end up with 584.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5840, and continue the process.

On to step 11:
The number 638 fits into 5840 9 times, leaving a remainder of 98.
Write down 9 as next digit of the result. 
Result so far: 135911.829
Subtracting 5742 from 5840 leaves us with 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Advancing to step 12:
The number 638 fits into 980 1 times, leaving a remainder of 342.
Write down 1 as next digit of the result. 
Result so far: 135911.8291
If we take 638 away from 980, we end up with 342.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3420, and continue the process.

Step 13:
If we divide 3420 by 638, we get 5 and a remainder of 230.
Record the quotient 5 as the next digit in the result. 
Result so far: 135911.82915
Subtract 3190 from 3420 to get 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Moving on to step 14:
638 can be fit into 2300 3 times, resulting in a remainder of 386.
The next digit of our result is 3. 
Result so far: 135911.829153
The remainder is 386 after subtracting 1914 from 2300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3860, and continue the process.

Going ahead to step 15:
If we divide 3860 by 638, we get 6 and a remainder of 32.
The number 6 becomes the next digit in our result. 
Result so far: 135911.8291536
If we subtract 3828 from 3860, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 16:
If we divide 320 by 638, we get 0 and a remainder of 320.
Use 0 as the next digit of our solution. 
Result so far: 135911.8291536
Deduct 0 from 320 and we're left 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.

In conclusion, the division gives 135911.8291536 with a balance of 3.2e-07.
