Let's divide 83639496 by 638
Let's see how many times 638 fits into 83639496.

Moving on to step 1:
638 can be fit into 8 0 times, resulting in a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Grab the next digit (3) from the dividend, add it to 8, then carry on: 83 / 638

Let's proceed to step 2:
When dividing 83 by 638, we get 0 with a remainder of 83.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 83 leaves us with 83.
Take the next digit (6) from the dividend and append it to 83, then repeat: 836 / 638

Going ahead to step 3:
836 divided by 638 is 1 with a remainder of 198.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 638 from 836 to get 198.
Bring next digit (3) of the dividend behind the 198 and repeat the process: 1983 / 638

Let's proceed to step 4:
If we divide 1983 by 638, we get 3 and a remainder of 69.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
The remainder is 69 after subtracting 1914 from 1983.
Take the next digit (9) from the dividend and append it to 69, then repeat: 699 / 638

Moving on to step 5:
If we divide 699 by 638, we get 1 and a remainder of 61.
The next digit of our result is 1. 
Result so far: 131.0
The remainder is 61 after subtracting 638 from 699.
Append the next digit (4) from the dividend to 61 and continue with: 614 / 638

Going ahead to step 6:
614 divided by 638 is 0 with a remainder of 614.
The next digit of our result is 0. 
Result so far: 1310.0
Subtracting 0 from 614 leaves us with 614.
Bring next digit (9) of the dividend behind the 614 and repeat the process: 6149 / 638

Going ahead to step 7:
The number 638 fits into 6149 9 times, leaving a remainder of 407.
Record the quotient 9 as the next digit in the result. 
Result so far: 13109.0
Deduct 5742 from 6149 and we're left with 407.
Include the next digit (6) from the dividend after 407, then repeat: 4076 / 638

Let's proceed to step 8:
638 goes into 4076 6 times with a remainder of 248.
Put 6 as the next digit of the answer. 
Result so far: 131096.0
Deduct 3828 from 4076 and we're left with 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Let's proceed to step 9:
If we divide 2480 by 638, we get 3 and a remainder of 566.
Put 3 as the next digit of the answer. 
Result so far: 131096.3
Subtract 1914 from 2480 to get 566.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5660, and continue the process.

Let's proceed to step 10:
The number 638 fits into 5660 8 times, leaving a remainder of 556.
Put 8 as the next digit of the answer. 
Result so far: 131096.38
Subtracting 5104 from 5660 leaves us with 556.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5560, and continue the process.

Let's proceed to step 11:
5560 divided by 638 is 8 with a remainder of 456.
The next digit of our result is 8. 
Result so far: 131096.388
Subtracting 5104 from 5560 leaves us with 456.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4560, and continue the process.

The quotient of the division is 131096.388, and the remainder is 0.0456.
