Let's divide 87176649 by 639
Our goal is to divide 87176649 by 639.

Let's proceed to step 1:
639 goes into 8 0 times with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Bring next digit (7) of the dividend behind the 8 and repeat the process: 87 / 639

Let's proceed to step 2:
If we divide 87 by 639, we get 0 and a remainder of 87.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 87 leaves us with 87.
Include the next digit (1) from the dividend after 87, then repeat: 871 / 639

Step 3:
871 divided by 639 is 1 with a remainder of 232.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 639 from 871, we get 232.
Grab the next digit (7) from the dividend, add it to 232, then carry on: 2327 / 639

Going ahead to step 4:
639 goes into 2327 3 times with a remainder of 410.
The next digit of our result is 3. 
Result so far: 13.0
The remainder is 410 after subtracting 1917 from 2327.
Include the next digit (6) from the dividend after 410, then repeat: 4106 / 639

Step 5:
639 can be fit into 4106 6 times, resulting in a remainder of 272.
The next digit of our result is 6. 
Result so far: 136.0
Deduct 3834 from 4106 and we're left with 272.
Append the next digit (6) from the dividend to 272 and continue with: 2726 / 639

Step 6:
2726 divided by 639 is 4 with a remainder of 170.
Use 4 as the next digit of our solution. 
Result so far: 1364.0
The remainder is 170 after subtracting 2556 from 2726.
Append the next digit (4) from the dividend to 170 and continue with: 1704 / 639

Step 7:
639 can be fit into 1704 2 times, resulting in a remainder of 426.
The number 2 becomes the next digit in our result. 
Result so far: 13642.0
If we take 1278 away from 1704, we end up with 426.
Grab the next digit (9) from the dividend, add it to 426, then carry on: 4269 / 639

Advancing to step 8:
If we divide 4269 by 639, we get 6 and a remainder of 435.
Write down 6 as next digit of the result. 
Result so far: 136426.0
The remainder is 435 after subtracting 3834 from 4269.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4350, and continue the process.

Moving on to step 9:
The number 639 fits into 4350 6 times, leaving a remainder of 516.
Write down 6 as next digit of the result. 
Result so far: 136426.6
Deduct 3834 from 4350 and we're left with 516.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5160, and continue the process.

Advancing to step 10:
When dividing 5160 by 639, we get 8 with a remainder of 48.
Write down 8 as next digit of the result. 
Result so far: 136426.68
If we take 5112 away from 5160, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 11:
When dividing 480 by 639, we get 0 with a remainder of 480.
The number 0 becomes the next digit in our result. 
Result so far: 136426.68
Deduct 0 from 480 and we're left with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

On to step 12:
When dividing 4800 by 639, we get 7 with a remainder of 327.
Record the quotient 7 as the next digit in the result. 
Result so far: 136426.6807
If we subtract 4473 from 4800, we get 327.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3270, and continue the process.

Advancing to step 13:
639 can be fit into 3270 5 times, resulting in a remainder of 75.
Write down 5 as next digit of the result. 
Result so far: 136426.68075
Deduct 3195 from 3270 and we're left with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

On to step 14:
The number 639 fits into 750 1 times, leaving a remainder of 111.
The number 1 becomes the next digit in our result. 
Result so far: 136426.680751
Subtract 639 from 750 to get 111.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1110, and continue the process.

Step 15:
639 goes into 1110 1 times with a remainder of 471.
Record the quotient 1 as the next digit in the result. 
Result so far: 136426.6807511
Deduct 639 from 1110 and we're left with 471.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4710, and continue the process.

The final outcome is 136426.6807511, with a leftover of 4.71e-06.
