We're dividing 91056555 by 415 
We want to figure out the number of times 91056555 can be divided by 415.

On to step 1:
9 divided by 415 is 0 with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Include the next digit (1) from the dividend after 9, then repeat: 91 / 415

Advancing to step 2:
415 goes into 91 0 times with a remainder of 91.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 91 after subtracting 0 from 91.
Fetch the next digit (0) from the dividend, attach it to 91 and continue: 910 / 415

Going ahead to step 3:
When dividing 910 by 415, we get 2 with a remainder of 80.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 830 away from 910, we end up with 80.
Include the next digit (5) from the dividend after 80, then repeat: 805 / 415

Going ahead to step 4:
If we divide 805 by 415, we get 1 and a remainder of 390.
Put 1 as the next digit of the answer. 
Result so far: 21.0
If we take 415 away from 805, we end up with 390.
Grab the next digit (6) from the dividend, add it to 390, then carry on: 3906 / 415

Advancing to step 5:
The number 415 fits into 3906 9 times, leaving a remainder of 171.
Write down 9 as next digit of the result. 
Result so far: 219.0
Subtract 3735 from 3906 to get 171.
Take the next digit (5) from the dividend and append it to 171, then repeat: 1715 / 415

Moving on to step 6:
If we divide 1715 by 415, we get 4 and a remainder of 55.
Put 4 as the next digit of the answer. 
Result so far: 2194.0
If we take 1660 away from 1715, we end up with 55.
Fetch the next digit (5) from the dividend, attach it to 55 and continue: 555 / 415

Let's proceed to step 7:
When dividing 555 by 415, we get 1 with a remainder of 140.
Record the quotient 1 as the next digit in the result. 
Result so far: 21941.0
Subtract 415 from 555 to get 140.
Grab the next digit (5) from the dividend, add it to 140, then carry on: 1405 / 415

On to step 8:
When dividing 1405 by 415, we get 3 with a remainder of 160.
Put 3 as the next digit of the answer. 
Result so far: 219413.0
Subtract 1245 from 1405 to get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Going ahead to step 9:
The number 415 fits into 1600 3 times, leaving a remainder of 355.
The number 3 becomes the next digit in our result. 
Result so far: 219413.3
Subtracting 1245 from 1600 leaves us with 355.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3550, and continue the process.

Let's proceed to step 10:
415 goes into 3550 8 times with a remainder of 230.
Write down 8 as next digit of the result. 
Result so far: 219413.38
If we subtract 3320 from 3550, we get 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Moving on to step 11:
If we divide 2300 by 415, we get 5 and a remainder of 225.
Use 5 as the next digit of our solution. 
Result so far: 219413.385
Deduct 2075 from 2300 and we're left with 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

Let's proceed to step 12:
If we divide 2250 by 415, we get 5 and a remainder of 175.
Use 5 as the next digit of our solution. 
Result so far: 219413.3855
The remainder is 175 after subtracting 2075 from 2250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

The final result is 219413.3855 with a remainder of 0.00175.
