We're dividing 91253579 by 485 
We're looking to find how many times 485 goes into 91253579.

Step 1:
485 can be fit into 9 0 times, resulting in a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Append the next digit (1) from the dividend to 9 and continue with: 91 / 485

On to step 2:
The number 485 fits into 91 0 times, leaving a remainder of 91.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 91 and we're left with 91.
Take the next digit (2) from the dividend and append it to 91, then repeat: 912 / 485

On to step 3:
485 can be fit into 912 1 times, resulting in a remainder of 427.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 427 after subtracting 485 from 912.
Bring next digit (5) of the dividend behind the 427 and repeat the process: 4275 / 485

Going ahead to step 4:
When dividing 4275 by 485, we get 8 with a remainder of 395.
The number 8 becomes the next digit in our result. 
Result so far: 18.0
Subtract 3880 from 4275 to get 395.
Include the next digit (3) from the dividend after 395, then repeat: 3953 / 485

On to step 5:
The number 485 fits into 3953 8 times, leaving a remainder of 73.
Record the quotient 8 as the next digit in the result. 
Result so far: 188.0
The remainder is 73 after subtracting 3880 from 3953.
Grab the next digit (5) from the dividend, add it to 73, then carry on: 735 / 485

Advancing to step 6:
485 goes into 735 1 times with a remainder of 250.
Record the quotient 1 as the next digit in the result. 
Result so far: 1881.0
Subtracting 485 from 735 leaves us with 250.
Fetch the next digit (7) from the dividend, attach it to 250 and continue: 2507 / 485

Going ahead to step 7:
485 can be fit into 2507 5 times, resulting in a remainder of 82.
Record the quotient 5 as the next digit in the result. 
Result so far: 18815.0
The remainder is 82 after subtracting 2425 from 2507.
Append the next digit (9) from the dividend to 82 and continue with: 829 / 485

On to step 8:
829 divided by 485 is 1 with a remainder of 344.
Put 1 as the next digit of the answer. 
Result so far: 188151.0
If we subtract 485 from 829, we get 344.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

Going ahead to step 9:
3440 divided by 485 is 7 with a remainder of 45.
Record the quotient 7 as the next digit in the result. 
Result so far: 188151.7
Deduct 3395 from 3440 and we're left with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Advancing to step 10:
If we divide 450 by 485, we get 0 and a remainder of 450.
The next digit of our result is 0. 
Result so far: 188151.7
Subtract 0 from 450 to get 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

Going ahead to step 11:
485 can be fit into 4500 9 times, resulting in a remainder of 135.
The next digit of our result is 9. 
Result so far: 188151.709
If we subtract 4365 from 4500, we get 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Let's proceed to step 12:
485 goes into 1350 2 times with a remainder of 380.
Put 2 as the next digit of the answer. 
Result so far: 188151.7092
Deduct 970 from 1350 and we're left with 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Step 13:
The number 485 fits into 3800 7 times, leaving a remainder of 405.
Put 7 as the next digit of the answer. 
Result so far: 188151.70927
Subtract 3395 from 3800 to get 405.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4050, and continue the process.

Step 14:
If we divide 4050 by 485, we get 8 and a remainder of 170.
The next digit of our result is 8. 
Result so far: 188151.709278
Deduct 3880 from 4050 and we're left with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Let's proceed to step 15:
If we divide 1700 by 485, we get 3 and a remainder of 245.
Use 3 as the next digit of our solution. 
Result so far: 188151.7092783
Subtracting 1455 from 1700 leaves us with 245.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2450, and continue the process.

Step 16:
485 goes into 2450 5 times with a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 188151.70927835
The remainder is 25 after subtracting 2425 from 2450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

The final result is 188151.70927835 with a remainder of 2.5e-08.
