Let's divide 83851373 by 816
Our goal is to divide 83851373 by 816.

Moving on to step 1:
The number 816 fits into 8 0 times, leaving a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Fetch the next digit (3) from the dividend, attach it to 8 and continue: 83 / 816

Going ahead to step 2:
When dividing 83 by 816, we get 0 with a remainder of 83.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 83 to get 83.
Take the next digit (8) from the dividend and append it to 83, then repeat: 838 / 816

Let's proceed to step 3:
816 goes into 838 1 times with a remainder of 22.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 816 from 838, we get 22.
Include the next digit (5) from the dividend after 22, then repeat: 225 / 816

On to step 4:
816 goes into 225 0 times with a remainder of 225.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Deduct 0 from 225 and we're left with 225.
Append the next digit (1) from the dividend to 225 and continue with: 2251 / 816

Advancing to step 5:
2251 divided by 816 is 2 with a remainder of 619.
Put 2 as the next digit of the answer. 
Result so far: 102.0
Subtracting 1632 from 2251 leaves us with 619.
Grab the next digit (3) from the dividend, add it to 619, then carry on: 6193 / 816

Let's proceed to step 6:
The number 816 fits into 6193 7 times, leaving a remainder of 481.
The number 7 becomes the next digit in our result. 
Result so far: 1027.0
The remainder is 481 after subtracting 5712 from 6193.
Fetch the next digit (7) from the dividend, attach it to 481 and continue: 4817 / 816

Advancing to step 7:
When dividing 4817 by 816, we get 5 with a remainder of 737.
Use 5 as the next digit of our solution. 
Result so far: 10275.0
Subtract 4080 from 4817 to get 737.
Append the next digit (3) from the dividend to 737 and continue with: 7373 / 816

On to step 8:
7373 divided by 816 is 9 with a remainder of 29.
Write down 9 as next digit of the result. 
Result so far: 102759.0
The remainder is 29 after subtracting 7344 from 7373.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Advancing to step 9:
When dividing 290 by 816, we get 0 with a remainder of 290.
Write down 0 as next digit of the result. 
Result so far: 102759.0
The remainder is 290 after subtracting 0 from 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Moving on to step 10:
2900 divided by 816 is 3 with a remainder of 452.
Record the quotient 3 as the next digit in the result. 
Result so far: 102759.03
Subtracting 2448 from 2900 leaves us with 452.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4520, and continue the process.

Let's proceed to step 11:
The number 816 fits into 4520 5 times, leaving a remainder of 440.
Record the quotient 5 as the next digit in the result. 
Result so far: 102759.035
Subtracting 4080 from 4520 leaves us with 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

On to step 12:
If we divide 4400 by 816, we get 5 and a remainder of 320.
Put 5 as the next digit of the answer. 
Result so far: 102759.0355
The remainder is 320 after subtracting 4080 from 4400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

In conclusion, the division gives 102759.0355 with a balance of 0.0032.
