We look at the division of 8321911 by 858 
We want to figure out the number of times 8321911 can be divided by 858.

Advancing to step 1:
The number 858 fits into 8 0 times, leaving a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Grab the next digit (3) from the dividend, add it to 8, then carry on: 83 / 858

Advancing to step 2:
If we divide 83 by 858, we get 0 and a remainder of 83.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 83 leaves us with 83.
Bring next digit (2) of the dividend behind the 83 and repeat the process: 832 / 858

On to step 3:
When dividing 832 by 858, we get 0 with a remainder of 832.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 832 and we're left with 832.
Take the next digit (1) from the dividend and append it to 832, then repeat: 8321 / 858

Step 4:
858 can be fit into 8321 9 times, resulting in a remainder of 599.
The next digit of our result is 9. 
Result so far: 9.0
The remainder is 599 after subtracting 7722 from 8321.
Take the next digit (9) from the dividend and append it to 599, then repeat: 5999 / 858

Let's proceed to step 5:
The number 858 fits into 5999 6 times, leaving a remainder of 851.
Put 6 as the next digit of the answer. 
Result so far: 96.0
Deduct 5148 from 5999 and we're left with 851.
Fetch the next digit (1) from the dividend, attach it to 851 and continue: 8511 / 858

Going ahead to step 6:
When dividing 8511 by 858, we get 9 with a remainder of 789.
Write down 9 as next digit of the result. 
Result so far: 969.0
If we subtract 7722 from 8511, we get 789.
Fetch the next digit (1) from the dividend, attach it to 789 and continue: 7891 / 858

Going ahead to step 7:
When dividing 7891 by 858, we get 9 with a remainder of 169.
Use 9 as the next digit of our solution. 
Result so far: 9699.0
The remainder is 169 after subtracting 7722 from 7891.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1690, and continue the process.

Let's proceed to step 8:
If we divide 1690 by 858, we get 1 and a remainder of 832.
The next digit of our result is 1. 
Result so far: 9699.1
Deduct 858 from 1690 and we're left with 832.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8320, and continue the process.

On to step 9:
The number 858 fits into 8320 9 times, leaving a remainder of 598.
Use 9 as the next digit of our solution. 
Result so far: 9699.19
If we subtract 7722 from 8320, we get 598.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5980, and continue the process.

Advancing to step 10:
858 goes into 5980 6 times with a remainder of 832.
Write down 6 as next digit of the result. 
Result so far: 9699.196
Subtract 5148 from 5980 to get 832.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8320, and continue the process.

Moving on to step 11:
The number 858 fits into 8320 9 times, leaving a remainder of 598.
Put 9 as the next digit of the answer. 
Result so far: 9699.1969
The remainder is 598 after subtracting 7722 from 8320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5980, and continue the process.

Moving on to step 12:
The number 858 fits into 5980 6 times, leaving a remainder of 832.
Use 6 as the next digit of our solution. 
Result so far: 9699.19696
Deduct 5148 from 5980 and we're left with 832.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8320, and continue the process.

Moving on to step 13:
858 can be fit into 8320 9 times, resulting in a remainder of 598.
Write down 9 as next digit of the result. 
Result so far: 9699.196969
Deduct 7722 from 8320 and we're left with 598.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5980, and continue the process.

Let's proceed to step 14:
858 can be fit into 5980 6 times, resulting in a remainder of 832.
The next digit of our result is 6. 
Result so far: 9699.1969696
If we subtract 5148 from 5980, we get 832.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8320, and continue the process.

On to step 15:
8320 divided by 858 is 9 with a remainder of 598.
Put 9 as the next digit of the answer. 
Result so far: 9699.19696969
Deduct 7722 from 8320 and we're left with 598.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5980, and continue the process.

The final outcome is 9699.19696969, with a leftover of 5.98e-07.
