851138 ÷ 83 
We want to figure out the number of times 851138 can be divided by 83.

Going ahead to step 1:
83 goes into 8 0 times with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Take the next digit (5) from the dividend and append it to 8, then repeat: 85 / 83

On to step 2:
85 divided by 83 is 1 with a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 83 from 85 and we're left with 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 83

Advancing to step 3:
If we divide 21 by 83, we get 0 and a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 10.0
The remainder is 21 after subtracting 0 from 21.
Append the next digit (1) from the dividend to 21 and continue with: 211 / 83

Let's proceed to step 4:
The number 83 fits into 211 2 times, leaving a remainder of 45.
Put 2 as the next digit of the answer. 
Result so far: 102.0
The remainder is 45 after subtracting 166 from 211.
Fetch the next digit (3) from the dividend, attach it to 45 and continue: 453 / 83

Moving on to step 5:
453 divided by 83 is 5 with a remainder of 38.
The number 5 becomes the next digit in our result. 
Result so far: 1025.0
Subtract 415 from 453 to get 38.
Bring next digit (8) of the dividend behind the 38 and repeat the process: 388 / 83

Let's proceed to step 6:
83 can be fit into 388 4 times, resulting in a remainder of 56.
Write down 4 as next digit of the result. 
Result so far: 10254.0
If we subtract 332 from 388, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Moving on to step 7:
If we divide 560 by 83, we get 6 and a remainder of 62.
Write down 6 as next digit of the result. 
Result so far: 10254.6
If we subtract 498 from 560, we get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

On to step 8:
83 goes into 620 7 times with a remainder of 39.
Use 7 as the next digit of our solution. 
Result so far: 10254.67
If we subtract 581 from 620, we get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Step 9:
83 can be fit into 390 4 times, resulting in a remainder of 58.
Use 4 as the next digit of our solution. 
Result so far: 10254.674
If we subtract 332 from 390, we get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Advancing to step 10:
580 divided by 83 is 6 with a remainder of 82.
Record the quotient 6 as the next digit in the result. 
Result so far: 10254.6746
Subtracting 498 from 580 leaves us with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

On to step 11:
If we divide 820 by 83, we get 9 and a remainder of 73.
The number 9 becomes the next digit in our result. 
Result so far: 10254.67469
If we take 747 away from 820, 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.

Going ahead to step 12:
If we divide 730 by 83, we get 8 and a remainder of 66.
The next digit of our result is 8. 
Result so far: 10254.674698
The remainder is 66 after subtracting 664 from 730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Going ahead to step 13:
The number 83 fits into 660 7 times, leaving a remainder of 79.
Write down 7 as next digit of the result. 
Result so far: 10254.6746987
Subtracting 581 from 660 leaves us with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Step 14:
83 can be fit into 790 9 times, resulting in a remainder of 43.
Put 9 as the next digit of the answer. 
Result so far: 10254.67469879
Deduct 747 from 790 and we're left with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

The final outcome is 10254.67469879, with a leftover of 4.3e-08.
