We look at the division of 86101162 by 84 
We're looking to find how many times 84 goes into 86101162.

On to step 1:
The number 84 fits into 8 0 times, leaving a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 84

Let's proceed to step 2:
84 can be fit into 86 1 times, resulting in a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 2 after subtracting 84 from 86.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 84

Going ahead to step 3:
84 goes into 21 0 times with a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Deduct 0 from 21 and we're left with 21.
Grab the next digit (0) from the dividend, add it to 21, then carry on: 210 / 84

On to step 4:
When dividing 210 by 84, we get 2 with a remainder of 42.
Write down 2 as next digit of the result. 
Result so far: 102.0
Deduct 168 from 210 and we're left with 42.
Append the next digit (1) from the dividend to 42 and continue with: 421 / 84

Advancing to step 5:
84 can be fit into 421 5 times, resulting in a remainder of 1.
Record the quotient 5 as the next digit in the result. 
Result so far: 1025.0
If we take 420 away from 421, we end up with 1.
Take the next digit (1) from the dividend and append it to 1, then repeat: 11 / 84

Moving on to step 6:
If we divide 11 by 84, we get 0 and a remainder of 11.
The next digit of our result is 0. 
Result so far: 10250.0
If we take 0 away from 11, we end up with 11.
Grab the next digit (6) from the dividend, add it to 11, then carry on: 116 / 84

Let's proceed to step 7:
When dividing 116 by 84, we get 1 with a remainder of 32.
The next digit of our result is 1. 
Result so far: 102501.0
Deduct 84 from 116 and we're left with 32.
Fetch the next digit (2) from the dividend, attach it to 32 and continue: 322 / 84

Advancing to step 8:
84 goes into 322 3 times with a remainder of 70.
Record the quotient 3 as the next digit in the result. 
Result so far: 1025013.0
Subtract 252 from 322 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 9:
If we divide 700 by 84, we get 8 and a remainder of 28.
Record the quotient 8 as the next digit in the result. 
Result so far: 1025013.8
If we take 672 away from 700, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 10:
The number 84 fits into 280 3 times, leaving a remainder of 28.
The number 3 becomes the next digit in our result. 
Result so far: 1025013.83
If we take 252 away from 280, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 11:
280 divided by 84 is 3 with a remainder of 28.
The number 3 becomes the next digit in our result. 
Result so far: 1025013.833
If we subtract 252 from 280, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

The final result is 1025013.833 with a remainder of 0.0028.
