We divide 76565879 by 639
Our goal is to divide 76565879 by 639.

On to step 1:
When dividing 7 by 639, we get 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Bring next digit (6) of the dividend behind the 7 and repeat the process: 76 / 639

Step 2:
The number 639 fits into 76 0 times, leaving a remainder of 76.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 76 and we're left with 76.
Take the next digit (5) from the dividend and append it to 76, then repeat: 765 / 639

Moving on to step 3:
If we divide 765 by 639, we get 1 and a remainder of 126.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 639 from 765 to get 126.
Fetch the next digit (6) from the dividend, attach it to 126 and continue: 1266 / 639

Moving on to step 4:
639 can be fit into 1266 1 times, resulting in a remainder of 627.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
If we take 639 away from 1266, we end up with 627.
Grab the next digit (5) from the dividend, add it to 627, then carry on: 6275 / 639

Moving on to step 5:
639 goes into 6275 9 times with a remainder of 524.
Put 9 as the next digit of the answer. 
Result so far: 119.0
Subtract 5751 from 6275 to get 524.
Append the next digit (8) from the dividend to 524 and continue with: 5248 / 639

Moving on to step 6:
The number 639 fits into 5248 8 times, leaving a remainder of 136.
Write down 8 as next digit of the result. 
Result so far: 1198.0
Subtracting 5112 from 5248 leaves us with 136.
Grab the next digit (7) from the dividend, add it to 136, then carry on: 1367 / 639

Moving on to step 7:
1367 divided by 639 is 2 with a remainder of 89.
Record the quotient 2 as the next digit in the result. 
Result so far: 11982.0
Deduct 1278 from 1367 and we're left with 89.
Append the next digit (9) from the dividend to 89 and continue with: 899 / 639

Step 8:
639 can be fit into 899 1 times, resulting in a remainder of 260.
Write down 1 as next digit of the result. 
Result so far: 119821.0
Subtract 639 from 899 to get 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Advancing to step 9:
If we divide 2600 by 639, we get 4 and a remainder of 44.
The number 4 becomes the next digit in our result. 
Result so far: 119821.4
Subtract 2556 from 2600 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Advancing to step 10:
639 goes into 440 0 times with a remainder of 440.
The next digit of our result is 0. 
Result so far: 119821.4
Subtract 0 from 440 to get 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

On to step 11:
639 can be fit into 4400 6 times, resulting in a remainder of 566.
The next digit of our result is 6. 
Result so far: 119821.406
Subtracting 3834 from 4400 leaves us with 566.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5660, and continue the process.

On to step 12:
639 can be fit into 5660 8 times, resulting in a remainder of 548.
Record the quotient 8 as the next digit in the result. 
Result so far: 119821.4068
Deduct 5112 from 5660 and we're left with 548.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5480, and continue the process.

Step 13:
5480 divided by 639 is 8 with a remainder of 368.
Use 8 as the next digit of our solution. 
Result so far: 119821.40688
If we subtract 5112 from 5480, we get 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

The final outcome is 119821.40688, with a leftover of 0.000368.
