We divide 91720818 by 478
We want to divide 91720818 by 478.

On to step 1:
When dividing 9 by 478, we get 0 with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Take the next digit (1) from the dividend and append it to 9, then repeat: 91 / 478

Let's proceed to step 2:
91 divided by 478 is 0 with a remainder of 91.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 91, we end up with 91.
Take the next digit (7) from the dividend and append it to 91, then repeat: 917 / 478

Let's proceed to step 3:
478 goes into 917 1 times with a remainder of 439.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 439 after subtracting 478 from 917.
Grab the next digit (2) from the dividend, add it to 439, then carry on: 4392 / 478

Step 4:
The number 478 fits into 4392 9 times, leaving a remainder of 90.
Use 9 as the next digit of our solution. 
Result so far: 19.0
Deduct 4302 from 4392 and we're left with 90.
Grab the next digit (0) from the dividend, add it to 90, then carry on: 900 / 478

Let's proceed to step 5:
When dividing 900 by 478, we get 1 with a remainder of 422.
Put 1 as the next digit of the answer. 
Result so far: 191.0
Deduct 478 from 900 and we're left with 422.
Include the next digit (8) from the dividend after 422, then repeat: 4228 / 478

Advancing to step 6:
The number 478 fits into 4228 8 times, leaving a remainder of 404.
Write down 8 as next digit of the result. 
Result so far: 1918.0
Deduct 3824 from 4228 and we're left with 404.
Grab the next digit (1) from the dividend, add it to 404, then carry on: 4041 / 478

Going ahead to step 7:
4041 divided by 478 is 8 with a remainder of 217.
Write down 8 as next digit of the result. 
Result so far: 19188.0
If we subtract 3824 from 4041, we get 217.
Fetch the next digit (8) from the dividend, attach it to 217 and continue: 2178 / 478

Going ahead to step 8:
478 can be fit into 2178 4 times, resulting in a remainder of 266.
The next digit of our result is 4. 
Result so far: 191884.0
Subtracting 1912 from 2178 leaves us with 266.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2660, and continue the process.

Moving on to step 9:
478 can be fit into 2660 5 times, resulting in a remainder of 270.
Record the quotient 5 as the next digit in the result. 
Result so far: 191884.5
If we take 2390 away from 2660, we end up with 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Advancing to step 10:
478 can be fit into 2700 5 times, resulting in a remainder of 310.
Write down 5 as next digit of the result. 
Result so far: 191884.55
If we subtract 2390 from 2700, we get 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

In conclusion, the division gives 191884.55 with a balance of 0.31.
