We're dividing 99602125 by 858 
We're looking to find how many times 858 goes into 99602125.

Going ahead to step 1:
858 can be fit into 9 0 times, resulting in a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Grab the next digit (9) from the dividend, add it to 9, then carry on: 99 / 858

Moving on to step 2:
The number 858 fits into 99 0 times, leaving a remainder of 99.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 99 leaves us with 99.
Take the next digit (6) from the dividend and append it to 99, then repeat: 996 / 858

Let's proceed to step 3:
858 goes into 996 1 times with a remainder of 138.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 858 from 996 to get 138.
Fetch the next digit (0) from the dividend, attach it to 138 and continue: 1380 / 858

Going ahead to step 4:
If we divide 1380 by 858, we get 1 and a remainder of 522.
Write down 1 as next digit of the result. 
Result so far: 11.0
Deduct 858 from 1380 and we're left with 522.
Bring next digit (2) of the dividend behind the 522 and repeat the process: 5222 / 858

Advancing to step 5:
5222 divided by 858 is 6 with a remainder of 74.
The number 6 becomes the next digit in our result. 
Result so far: 116.0
If we subtract 5148 from 5222, we get 74.
Bring next digit (1) of the dividend behind the 74 and repeat the process: 741 / 858

Let's proceed to step 6:
If we divide 741 by 858, we get 0 and a remainder of 741.
The next digit of our result is 0. 
Result so far: 1160.0
Deduct 0 from 741 and we're left with 741.
Fetch the next digit (2) from the dividend, attach it to 741 and continue: 7412 / 858

On to step 7:
When dividing 7412 by 858, we get 8 with a remainder of 548.
Write down 8 as next digit of the result. 
Result so far: 11608.0
Subtracting 6864 from 7412 leaves us with 548.
Include the next digit (5) from the dividend after 548, then repeat: 5485 / 858

Moving on to step 8:
The number 858 fits into 5485 6 times, leaving a remainder of 337.
Write down 6 as next digit of the result. 
Result so far: 116086.0
Deduct 5148 from 5485 and we're left with 337.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3370, and continue the process.

Advancing to step 9:
If we divide 3370 by 858, we get 3 and a remainder of 796.
Record the quotient 3 as the next digit in the result. 
Result so far: 116086.3
The remainder is 796 after subtracting 2574 from 3370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7960, and continue the process.

Let's proceed to step 10:
If we divide 7960 by 858, we get 9 and a remainder of 238.
Write down 9 as next digit of the result. 
Result so far: 116086.39
If we subtract 7722 from 7960, we get 238.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

On to step 11:
858 can be fit into 2380 2 times, resulting in a remainder of 664.
Write down 2 as next digit of the result. 
Result so far: 116086.392
The remainder is 664 after subtracting 1716 from 2380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6640, and continue the process.

On to step 12:
858 can be fit into 6640 7 times, resulting in a remainder of 634.
Use 7 as the next digit of our solution. 
Result so far: 116086.3927
If we subtract 6006 from 6640, we get 634.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6340, and continue the process.

Moving on to step 13:
858 goes into 6340 7 times with a remainder of 334.
Put 7 as the next digit of the answer. 
Result so far: 116086.39277
If we subtract 6006 from 6340, we get 334.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3340, and continue the process.

The final result is 116086.39277 with a remainder of 0.000334.
