We divide 83639351 by 649
Our goal is to divide 83639351 by 649.

Step 1:
8 divided by 649 is 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Bring next digit (3) of the dividend behind the 8 and repeat the process: 83 / 649

Moving on to step 2:
If we divide 83 by 649, we get 0 and a remainder of 83.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 83 and we're left with 83.
Include the next digit (6) from the dividend after 83, then repeat: 836 / 649

On to step 3:
If we divide 836 by 649, we get 1 and a remainder of 187.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 649 from 836, we get 187.
Include the next digit (3) from the dividend after 187, then repeat: 1873 / 649

Advancing to step 4:
The number 649 fits into 1873 2 times, leaving a remainder of 575.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
The remainder is 575 after subtracting 1298 from 1873.
Take the next digit (9) from the dividend and append it to 575, then repeat: 5759 / 649

Advancing to step 5:
When dividing 5759 by 649, we get 8 with a remainder of 567.
Use 8 as the next digit of our solution. 
Result so far: 128.0
Deduct 5192 from 5759 and we're left with 567.
Take the next digit (3) from the dividend and append it to 567, then repeat: 5673 / 649

On to step 6:
When dividing 5673 by 649, we get 8 with a remainder of 481.
The number 8 becomes the next digit in our result. 
Result so far: 1288.0
Subtracting 5192 from 5673 leaves us with 481.
Include the next digit (5) from the dividend after 481, then repeat: 4815 / 649

Let's proceed to step 7:
When dividing 4815 by 649, we get 7 with a remainder of 272.
Record the quotient 7 as the next digit in the result. 
Result so far: 12887.0
Subtract 4543 from 4815 to get 272.
Grab the next digit (1) from the dividend, add it to 272, then carry on: 2721 / 649

Let's proceed to step 8:
When dividing 2721 by 649, we get 4 with a remainder of 125.
The number 4 becomes the next digit in our result. 
Result so far: 128874.0
If we subtract 2596 from 2721, we get 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Going ahead to step 9:
649 can be fit into 1250 1 times, resulting in a remainder of 601.
Record the quotient 1 as the next digit in the result. 
Result so far: 128874.1
The remainder is 601 after subtracting 649 from 1250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6010, and continue the process.

Advancing to step 10:
649 goes into 6010 9 times with a remainder of 169.
Write down 9 as next digit of the result. 
Result so far: 128874.19
Subtracting 5841 from 6010 leaves us with 169.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1690, and continue the process.

Going ahead to step 11:
1690 divided by 649 is 2 with a remainder of 392.
The next digit of our result is 2. 
Result so far: 128874.192
If we take 1298 away from 1690, we end up with 392.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3920, and continue the process.

Step 12:
3920 divided by 649 is 6 with a remainder of 26.
Write down 6 as next digit of the result. 
Result so far: 128874.1926
Deduct 3894 from 3920 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 13:
649 can be fit into 260 0 times, resulting in a remainder of 260.
The number 0 becomes the next digit in our result. 
Result so far: 128874.1926
The remainder is 260 after subtracting 0 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Let's proceed to step 14:
649 goes into 2600 4 times with a remainder of 4.
Write down 4 as next digit of the result. 
Result so far: 128874.192604
If we take 2596 away from 2600, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 15:
649 can be fit into 40 0 times, resulting in a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 128874.192604
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 16:
649 goes into 400 0 times with a remainder of 400.
Put 0 as the next digit of the answer. 
Result so far: 128874.192604
Deduct 0 from 400 and we're left with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

After the division, we end up with 128874.192604 and a remainder of 4e-07.
