Let's divide 84130334 by 639
We want to figure out the number of times 84130334 can be divided by 639.

On to step 1:
If we divide 8 by 639, we get 0 and a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Include the next digit (4) from the dividend after 8, then repeat: 84 / 639

Step 2:
If we divide 84 by 639, we get 0 and a remainder of 84.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 84 and we're left with 84.
Fetch the next digit (1) from the dividend, attach it to 84 and continue: 841 / 639

On to step 3:
The number 639 fits into 841 1 times, leaving a remainder of 202.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 639 from 841 leaves us with 202.
Take the next digit (3) from the dividend and append it to 202, then repeat: 2023 / 639

On to step 4:
639 can be fit into 2023 3 times, resulting in a remainder of 106.
Write down 3 as next digit of the result. 
Result so far: 13.0
If we subtract 1917 from 2023, we get 106.
Include the next digit (0) from the dividend after 106, then repeat: 1060 / 639

On to step 5:
The number 639 fits into 1060 1 times, leaving a remainder of 421.
Record the quotient 1 as the next digit in the result. 
Result so far: 131.0
If we take 639 away from 1060, we end up with 421.
Bring next digit (3) of the dividend behind the 421 and repeat the process: 4213 / 639

Let's proceed to step 6:
If we divide 4213 by 639, we get 6 and a remainder of 379.
Put 6 as the next digit of the answer. 
Result so far: 1316.0
The remainder is 379 after subtracting 3834 from 4213.
Take the next digit (3) from the dividend and append it to 379, then repeat: 3793 / 639

Step 7:
639 can be fit into 3793 5 times, resulting in a remainder of 598.
Record the quotient 5 as the next digit in the result. 
Result so far: 13165.0
Subtract 3195 from 3793 to get 598.
Take the next digit (4) from the dividend and append it to 598, then repeat: 5984 / 639

Step 8:
The number 639 fits into 5984 9 times, leaving a remainder of 233.
Put 9 as the next digit of the answer. 
Result so far: 131659.0
Subtracting 5751 from 5984 leaves us with 233.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2330, and continue the process.

Going ahead to step 9:
639 goes into 2330 3 times with a remainder of 413.
The number 3 becomes the next digit in our result. 
Result so far: 131659.3
If we subtract 1917 from 2330, we get 413.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4130, and continue the process.

Going ahead to step 10:
When dividing 4130 by 639, we get 6 with a remainder of 296.
Use 6 as the next digit of our solution. 
Result so far: 131659.36
Subtract 3834 from 4130 to get 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

Let's proceed to step 11:
2960 divided by 639 is 4 with a remainder of 404.
Record the quotient 4 as the next digit in the result. 
Result so far: 131659.364
Deduct 2556 from 2960 and we're left with 404.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4040, and continue the process.

Step 12:
639 can be fit into 4040 6 times, resulting in a remainder of 206.
The number 6 becomes the next digit in our result. 
Result so far: 131659.3646
If we take 3834 away from 4040, we end up with 206.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2060, and continue the process.

On to step 13:
The number 639 fits into 2060 3 times, leaving a remainder of 143.
Write down 3 as next digit of the result. 
Result so far: 131659.36463
If we subtract 1917 from 2060, we get 143.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1430, and continue the process.

On to step 14:
639 can be fit into 1430 2 times, resulting in a remainder of 152.
Put 2 as the next digit of the answer. 
Result so far: 131659.364632
The remainder is 152 after subtracting 1278 from 1430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

On to step 15:
The number 639 fits into 1520 2 times, leaving a remainder of 242.
The next digit of our result is 2. 
Result so far: 131659.3646322
If we subtract 1278 from 1520, we get 242.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2420, and continue the process.

The final outcome is 131659.3646322, with a leftover of 2.42e-06.
