Let's divide 99873501 by 851
We're looking to find how many times 851 goes into 99873501.

Advancing to step 1:
If we divide 9 by 851, we get 0 and a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Bring next digit (9) of the dividend behind the 9 and repeat the process: 99 / 851

On to step 2:
851 can be fit into 99 0 times, resulting in a remainder of 99.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 99 and we're left with 99.
Take the next digit (8) from the dividend and append it to 99, then repeat: 998 / 851

Advancing to step 3:
The number 851 fits into 998 1 times, leaving a remainder of 147.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 147 after subtracting 851 from 998.
Include the next digit (7) from the dividend after 147, then repeat: 1477 / 851

Moving on to step 4:
851 goes into 1477 1 times with a remainder of 626.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
If we subtract 851 from 1477, we get 626.
Include the next digit (3) from the dividend after 626, then repeat: 6263 / 851

Moving on to step 5:
If we divide 6263 by 851, we get 7 and a remainder of 306.
The number 7 becomes the next digit in our result. 
Result so far: 117.0
The remainder is 306 after subtracting 5957 from 6263.
Append the next digit (5) from the dividend to 306 and continue with: 3065 / 851

Advancing to step 6:
If we divide 3065 by 851, we get 3 and a remainder of 512.
Put 3 as the next digit of the answer. 
Result so far: 1173.0
Subtract 2553 from 3065 to get 512.
Grab the next digit (0) from the dividend, add it to 512, then carry on: 5120 / 851

Moving on to step 7:
The number 851 fits into 5120 6 times, leaving a remainder of 14.
The number 6 becomes the next digit in our result. 
Result so far: 11736.0
Subtract 5106 from 5120 to get 14.
Include the next digit (1) from the dividend after 14, then repeat: 141 / 851

Advancing to step 8:
The number 851 fits into 141 0 times, leaving a remainder of 141.
The number 0 becomes the next digit in our result. 
Result so far: 117360.0
Deduct 0 from 141 and we're left with 141.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1410, and continue the process.

On to step 9:
1410 divided by 851 is 1 with a remainder of 559.
The next digit of our result is 1. 
Result so far: 117360.1
Deduct 851 from 1410 and we're left with 559.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5590, and continue the process.

Step 10:
851 goes into 5590 6 times with a remainder of 484.
Write down 6 as next digit of the result. 
Result so far: 117360.16
If we take 5106 away from 5590, we end up with 484.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4840, and continue the process.

Let's proceed to step 11:
If we divide 4840 by 851, we get 5 and a remainder of 585.
The next digit of our result is 5. 
Result so far: 117360.165
If we take 4255 away from 4840, we end up with 585.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5850, and continue the process.

On to step 12:
5850 divided by 851 is 6 with a remainder of 744.
The number 6 becomes the next digit in our result. 
Result so far: 117360.1656
Deduct 5106 from 5850 and we're left with 744.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7440, and continue the process.

Going ahead to step 13:
851 can be fit into 7440 8 times, resulting in a remainder of 632.
The number 8 becomes the next digit in our result. 
Result so far: 117360.16568
Deduct 6808 from 7440 and we're left with 632.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6320, and continue the process.

Moving on to step 14:
851 can be fit into 6320 7 times, resulting in a remainder of 363.
Write down 7 as next digit of the result. 
Result so far: 117360.165687
If we subtract 5957 from 6320, we get 363.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3630, and continue the process.

Going ahead to step 15:
The number 851 fits into 3630 4 times, leaving a remainder of 226.
Record the quotient 4 as the next digit in the result. 
Result so far: 117360.1656874
Subtracting 3404 from 3630 leaves us with 226.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

Going ahead to step 16:
851 goes into 2260 2 times with a remainder of 558.
Write down 2 as next digit of the result. 
Result so far: 117360.16568742
Deduct 1702 from 2260 and we're left with 558.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5580, and continue the process.

The quotient of the division is 117360.16568742, and the remainder is 5.58e-07.
