We're dividing 91901820 by 72 
Let's see how many times 72 fits into 91901820.

Moving on to step 1:
9 divided by 72 is 0 with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Append the next digit (1) from the dividend to 9 and continue with: 91 / 72

Advancing to step 2:
If we divide 91 by 72, we get 1 and a remainder of 19.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 72 from 91 and we're left with 19.
Bring next digit (9) of the dividend behind the 19 and repeat the process: 199 / 72

On to step 3:
When dividing 199 by 72, we get 2 with a remainder of 55.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
If we subtract 144 from 199, we get 55.
Fetch the next digit (0) from the dividend, attach it to 55 and continue: 550 / 72

Advancing to step 4:
72 can be fit into 550 7 times, resulting in a remainder of 46.
Write down 7 as next digit of the result. 
Result so far: 127.0
Subtract 504 from 550 to get 46.
Grab the next digit (1) from the dividend, add it to 46, then carry on: 461 / 72

Step 5:
If we divide 461 by 72, we get 6 and a remainder of 29.
Put 6 as the next digit of the answer. 
Result so far: 1276.0
The remainder is 29 after subtracting 432 from 461.
Append the next digit (8) from the dividend to 29 and continue with: 298 / 72

Moving on to step 6:
The number 72 fits into 298 4 times, leaving a remainder of 10.
The next digit of our result is 4. 
Result so far: 12764.0
The remainder is 10 after subtracting 288 from 298.
Bring next digit (2) of the dividend behind the 10 and repeat the process: 102 / 72

On to step 7:
72 goes into 102 1 times with a remainder of 30.
Use 1 as the next digit of our solution. 
Result so far: 127641.0
If we take 72 away from 102, we end up with 30.
Include the next digit (0) from the dividend after 30, then repeat: 300 / 72

Advancing to step 8:
300 divided by 72 is 4 with a remainder of 12.
Write down 4 as next digit of the result. 
Result so far: 1276414.0
Subtracting 288 from 300 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 9:
72 can be fit into 120 1 times, resulting in a remainder of 48.
Use 1 as the next digit of our solution. 
Result so far: 1276414.1
If we subtract 72 from 120, we get 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:
When dividing 480 by 72, we get 6 with a remainder of 48.
The number 6 becomes the next digit in our result. 
Result so far: 1276414.16
Subtract 432 from 480 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 11:
The number 72 fits into 480 6 times, leaving a remainder of 48.
Put 6 as the next digit of the answer. 
Result so far: 1276414.166
If we take 432 away from 480, 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.

In conclusion, the division gives 1276414.166 with a balance of 0.0048.
