We look at the division of 91022227 by 861 
We want to figure out the number of times 91022227 can be divided by 861.

On to step 1:
9 divided by 861 is 0 with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Bring next digit (1) of the dividend behind the 9 and repeat the process: 91 / 861

Going ahead to step 2:
861 goes into 91 0 times with a remainder of 91.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 91, we end up with 91.
Take the next digit (0) from the dividend and append it to 91, then repeat: 910 / 861

Moving on to step 3:
861 goes into 910 1 times with a remainder of 49.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 861 from 910 and we're left with 49.
Take the next digit (2) from the dividend and append it to 49, then repeat: 492 / 861

Going ahead to step 4:
861 goes into 492 0 times with a remainder of 492.
The next digit of our result is 0. 
Result so far: 10.0
The remainder is 492 after subtracting 0 from 492.
Take the next digit (2) from the dividend and append it to 492, then repeat: 4922 / 861

Going ahead to step 5:
4922 divided by 861 is 5 with a remainder of 617.
Use 5 as the next digit of our solution. 
Result so far: 105.0
Subtract 4305 from 4922 to get 617.
Take the next digit (2) from the dividend and append it to 617, then repeat: 6172 / 861

Moving on to step 6:
6172 divided by 861 is 7 with a remainder of 145.
The next digit of our result is 7. 
Result so far: 1057.0
The remainder is 145 after subtracting 6027 from 6172.
Fetch the next digit (2) from the dividend, attach it to 145 and continue: 1452 / 861

Let's proceed to step 7:
861 can be fit into 1452 1 times, resulting in a remainder of 591.
The number 1 becomes the next digit in our result. 
Result so far: 10571.0
The remainder is 591 after subtracting 861 from 1452.
Take the next digit (7) from the dividend and append it to 591, then repeat: 5917 / 861

Step 8:
861 can be fit into 5917 6 times, resulting in a remainder of 751.
Use 6 as the next digit of our solution. 
Result so far: 105716.0
Deduct 5166 from 5917 and we're left with 751.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7510, and continue the process.

Moving on to step 9:
7510 divided by 861 is 8 with a remainder of 622.
Use 8 as the next digit of our solution. 
Result so far: 105716.8
If we subtract 6888 from 7510, we get 622.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6220, and continue the process.

Let's proceed to step 10:
When dividing 6220 by 861, we get 7 with a remainder of 193.
The next digit of our result is 7. 
Result so far: 105716.87
Subtracting 6027 from 6220 leaves us with 193.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1930, and continue the process.

Let's proceed to step 11:
861 can be fit into 1930 2 times, resulting in a remainder of 208.
The next digit of our result is 2. 
Result so far: 105716.872
The remainder is 208 after subtracting 1722 from 1930.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Moving on to step 12:
2080 divided by 861 is 2 with a remainder of 358.
The next digit of our result is 2. 
Result so far: 105716.8722
The remainder is 358 after subtracting 1722 from 2080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3580, and continue the process.

Our division results in 105716.8722 with a remaining 0.00358.
