We divide 83829131 by 643
Our goal is to divide 83829131 by 643.

Going ahead to step 1:
8 divided by 643 is 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Take the next digit (3) from the dividend and append it to 8, then repeat: 83 / 643

Moving on to step 2:
643 goes into 83 0 times with a remainder of 83.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 83 leaves us with 83.
Bring next digit (8) of the dividend behind the 83 and repeat the process: 838 / 643

Going ahead to step 3:
643 goes into 838 1 times with a remainder of 195.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 643 from 838, we get 195.
Bring next digit (2) of the dividend behind the 195 and repeat the process: 1952 / 643

Moving on to step 4:
643 goes into 1952 3 times with a remainder of 23.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
The remainder is 23 after subtracting 1929 from 1952.
Include the next digit (9) from the dividend after 23, then repeat: 239 / 643

Advancing to step 5:
239 divided by 643 is 0 with a remainder of 239.
The number 0 becomes the next digit in our result. 
Result so far: 130.0
Deduct 0 from 239 and we're left with 239.
Append the next digit (1) from the dividend to 239 and continue with: 2391 / 643

On to step 6:
When dividing 2391 by 643, we get 3 with a remainder of 462.
Put 3 as the next digit of the answer. 
Result so far: 1303.0
If we subtract 1929 from 2391, we get 462.
Include the next digit (3) from the dividend after 462, then repeat: 4623 / 643

Moving on to step 7:
643 can be fit into 4623 7 times, resulting in a remainder of 122.
Record the quotient 7 as the next digit in the result. 
Result so far: 13037.0
The remainder is 122 after subtracting 4501 from 4623.
Take the next digit (1) from the dividend and append it to 122, then repeat: 1221 / 643

Step 8:
1221 divided by 643 is 1 with a remainder of 578.
Put 1 as the next digit of the answer. 
Result so far: 130371.0
If we take 643 away from 1221, we end up with 578.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5780, and continue the process.

Step 9:
5780 divided by 643 is 8 with a remainder of 636.
Put 8 as the next digit of the answer. 
Result so far: 130371.8
Deduct 5144 from 5780 and we're left with 636.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6360, and continue the process.

On to step 10:
When dividing 6360 by 643, we get 9 with a remainder of 573.
Put 9 as the next digit of the answer. 
Result so far: 130371.89
Subtracting 5787 from 6360 leaves us with 573.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5730, and continue the process.

Advancing to step 11:
5730 divided by 643 is 8 with a remainder of 586.
Use 8 as the next digit of our solution. 
Result so far: 130371.898
Subtracting 5144 from 5730 leaves us with 586.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5860, and continue the process.

Let's proceed to step 12:
643 goes into 5860 9 times with a remainder of 73.
The next digit of our result is 9. 
Result so far: 130371.8989
If we take 5787 away from 5860, we end up with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Step 13:
When dividing 730 by 643, we get 1 with a remainder of 87.
Use 1 as the next digit of our solution. 
Result so far: 130371.89891
Subtract 643 from 730 to get 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Going ahead to step 14:
870 divided by 643 is 1 with a remainder of 227.
Put 1 as the next digit of the answer. 
Result so far: 130371.898911
Subtract 643 from 870 to get 227.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2270, and continue the process.

The final outcome is 130371.898911, with a leftover of 2.27e-05.
