81546198 divided by 858 
We want to divide 81546198 by 858.

Let's proceed to step 1:
8 divided by 858 is 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 858

Going ahead to step 2:
If we divide 81 by 858, we get 0 and a remainder of 81.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 81, we get 81.
Grab the next digit (5) from the dividend, add it to 81, then carry on: 815 / 858

Let's proceed to step 3:
When dividing 815 by 858, we get 0 with a remainder of 815.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 815 to get 815.
Include the next digit (4) from the dividend after 815, then repeat: 8154 / 858

Going ahead to step 4:
If we divide 8154 by 858, we get 9 and a remainder of 432.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
If we take 7722 away from 8154, we end up with 432.
Bring next digit (6) of the dividend behind the 432 and repeat the process: 4326 / 858

On to step 5:
858 can be fit into 4326 5 times, resulting in a remainder of 36.
Put 5 as the next digit of the answer. 
Result so far: 95.0
The remainder is 36 after subtracting 4290 from 4326.
Fetch the next digit (1) from the dividend, attach it to 36 and continue: 361 / 858

Moving on to step 6:
858 can be fit into 361 0 times, resulting in a remainder of 361.
The next digit of our result is 0. 
Result so far: 950.0
The remainder is 361 after subtracting 0 from 361.
Grab the next digit (9) from the dividend, add it to 361, then carry on: 3619 / 858

Moving on to step 7:
3619 divided by 858 is 4 with a remainder of 187.
Use 4 as the next digit of our solution. 
Result so far: 9504.0
The remainder is 187 after subtracting 3432 from 3619.
Take the next digit (8) from the dividend and append it to 187, then repeat: 1878 / 858

Let's proceed to step 8:
858 goes into 1878 2 times with a remainder of 162.
Use 2 as the next digit of our solution. 
Result so far: 95042.0
If we subtract 1716 from 1878, we get 162.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1620, and continue the process.

Moving on to step 9:
The number 858 fits into 1620 1 times, leaving a remainder of 762.
Write down 1 as next digit of the result. 
Result so far: 95042.1
If we take 858 away from 1620, we end up with 762.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7620, and continue the process.

On to step 10:
The number 858 fits into 7620 8 times, leaving a remainder of 756.
Put 8 as the next digit of the answer. 
Result so far: 95042.18
Deduct 6864 from 7620 and we're left with 756.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7560, and continue the process.

Going ahead to step 11:
When dividing 7560 by 858, we get 8 with a remainder of 696.
The number 8 becomes the next digit in our result. 
Result so far: 95042.188
Subtracting 6864 from 7560 leaves us with 696.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6960, and continue the process.

Our division results in 95042.188 with a remaining 0.0696.
