87692657 divided by 639 
We're looking to find how many times 639 goes into 87692657.

Moving on to step 1:
If we divide 8 by 639, we get 0 and a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Fetch the next digit (7) from the dividend, attach it to 8 and continue: 87 / 639

Step 2:
When dividing 87 by 639, we get 0 with a remainder of 87.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 87, we get 87.
Fetch the next digit (6) from the dividend, attach it to 87 and continue: 876 / 639

Let's proceed to step 3:
639 goes into 876 1 times with a remainder of 237.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 639 from 876 to get 237.
Take the next digit (9) from the dividend and append it to 237, then repeat: 2379 / 639

On to step 4:
639 can be fit into 2379 3 times, resulting in a remainder of 462.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
If we subtract 1917 from 2379, we get 462.
Fetch the next digit (2) from the dividend, attach it to 462 and continue: 4622 / 639

Advancing to step 5:
If we divide 4622 by 639, we get 7 and a remainder of 149.
Use 7 as the next digit of our solution. 
Result so far: 137.0
Subtracting 4473 from 4622 leaves us with 149.
Append the next digit (6) from the dividend to 149 and continue with: 1496 / 639

Step 6:
1496 divided by 639 is 2 with a remainder of 218.
Put 2 as the next digit of the answer. 
Result so far: 1372.0
The remainder is 218 after subtracting 1278 from 1496.
Append the next digit (5) from the dividend to 218 and continue with: 2185 / 639

Moving on to step 7:
The number 639 fits into 2185 3 times, leaving a remainder of 268.
Write down 3 as next digit of the result. 
Result so far: 13723.0
Deduct 1917 from 2185 and we're left with 268.
Append the next digit (7) from the dividend to 268 and continue with: 2687 / 639

Going ahead to step 8:
639 can be fit into 2687 4 times, resulting in a remainder of 131.
The number 4 becomes the next digit in our result. 
Result so far: 137234.0
Subtracting 2556 from 2687 leaves us with 131.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1310, and continue the process.

Step 9:
639 goes into 1310 2 times with a remainder of 32.
Put 2 as the next digit of the answer. 
Result so far: 137234.2
If we subtract 1278 from 1310, 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.

Advancing to step 10:
When dividing 320 by 639, we get 0 with a remainder of 320.
Record the quotient 0 as the next digit in the result. 
Result so far: 137234.2
Subtracting 0 from 320 leaves us 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.

Going ahead to step 11:
When dividing 3200 by 639, we get 5 with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 137234.205
If we subtract 3195 from 3200, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 12:
If we divide 50 by 639, we get 0 and a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 137234.205
Subtract 0 from 50 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 13:
639 goes into 500 0 times with a remainder of 500.
Record the quotient 0 as the next digit in the result. 
Result so far: 137234.205
Deduct 0 from 500 and we're left with 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

After the division, we end up with 137234.205 and a remainder of 0.0005.
