We're dividing 220172 by 91 
We're looking to find how many times 91 goes into 220172.

On to step 1:
The number 91 fits into 2 0 times, leaving a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Fetch the next digit (2) from the dividend, attach it to 2 and continue: 22 / 91

On to step 2:
The number 91 fits into 22 0 times, leaving a remainder of 22.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 22, we end up with 22.
Grab the next digit (0) from the dividend, add it to 22, then carry on: 220 / 91

Going ahead to step 3:
When dividing 220 by 91, we get 2 with a remainder of 38.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we take 182 away from 220, we end up with 38.
Bring next digit (1) of the dividend behind the 38 and repeat the process: 381 / 91

Moving on to step 4:
When dividing 381 by 91, we get 4 with a remainder of 17.
Put 4 as the next digit of the answer. 
Result so far: 24.0
Subtract 364 from 381 to get 17.
Append the next digit (7) from the dividend to 17 and continue with: 177 / 91

Step 5:
177 divided by 91 is 1 with a remainder of 86.
Record the quotient 1 as the next digit in the result. 
Result so far: 241.0
If we subtract 91 from 177, we get 86.
Bring next digit (2) of the dividend behind the 86 and repeat the process: 862 / 91

On to step 6:
862 divided by 91 is 9 with a remainder of 43.
Write down 9 as next digit of the result. 
Result so far: 2419.0
Subtract 819 from 862 to get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Advancing to step 7:
91 goes into 430 4 times with a remainder of 66.
Use 4 as the next digit of our solution. 
Result so far: 2419.4
If we subtract 364 from 430, we get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Let's proceed to step 8:
When dividing 660 by 91, we get 7 with a remainder of 23.
Put 7 as the next digit of the answer. 
Result so far: 2419.47
Subtract 637 from 660 to get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Step 9:
91 goes into 230 2 times with a remainder of 48.
Record the quotient 2 as the next digit in the result. 
Result so far: 2419.472
If we take 182 away from 230, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 10:
The number 91 fits into 480 5 times, leaving a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 2419.4725
Deduct 455 from 480 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 11:
When dividing 250 by 91, we get 2 with a remainder of 68.
Put 2 as the next digit of the answer. 
Result so far: 2419.47252
Deduct 182 from 250 and we're left with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Moving on to step 12:
The number 91 fits into 680 7 times, leaving a remainder of 43.
The next digit of our result is 7. 
Result so far: 2419.472527
Subtracting 637 from 680 leaves us with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Let's proceed to step 13:
91 goes into 430 4 times with a remainder of 66.
Use 4 as the next digit of our solution. 
Result so far: 2419.4725274
Subtracting 364 from 430 leaves us with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Step 14:
When dividing 660 by 91, we get 7 with a remainder of 23.
Put 7 as the next digit of the answer. 
Result so far: 2419.47252747
Deduct 637 from 660 and we're left with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

In conclusion, the division gives 2419.47252747 with a balance of 2.3e-08.
