Let's divide 91450980 by 816
We want to figure out the number of times 91450980 can be divided by 816.

Going ahead to step 1:
9 divided by 816 is 0 with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Fetch the next digit (1) from the dividend, attach it to 9 and continue: 91 / 816

Step 2:
91 divided by 816 is 0 with a remainder of 91.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 91 leaves us with 91.
Grab the next digit (4) from the dividend, add it to 91, then carry on: 914 / 816

Moving on to step 3:
914 divided by 816 is 1 with a remainder of 98.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 816 away from 914, we end up with 98.
Grab the next digit (5) from the dividend, add it to 98, then carry on: 985 / 816

Step 4:
When dividing 985 by 816, we get 1 with a remainder of 169.
Use 1 as the next digit of our solution. 
Result so far: 11.0
Subtract 816 from 985 to get 169.
Take the next digit (0) from the dividend and append it to 169, then repeat: 1690 / 816

Advancing to step 5:
If we divide 1690 by 816, we get 2 and a remainder of 58.
Put 2 as the next digit of the answer. 
Result so far: 112.0
The remainder is 58 after subtracting 1632 from 1690.
Take the next digit (9) from the dividend and append it to 58, then repeat: 589 / 816

On to step 6:
The number 816 fits into 589 0 times, leaving a remainder of 589.
Put 0 as the next digit of the answer. 
Result so far: 1120.0
If we subtract 0 from 589, we get 589.
Bring next digit (8) of the dividend behind the 589 and repeat the process: 5898 / 816

Going ahead to step 7:
If we divide 5898 by 816, we get 7 and a remainder of 186.
Use 7 as the next digit of our solution. 
Result so far: 11207.0
Subtracting 5712 from 5898 leaves us with 186.
Take the next digit (0) from the dividend and append it to 186, then repeat: 1860 / 816

On to step 8:
If we divide 1860 by 816, we get 2 and a remainder of 228.
The next digit of our result is 2. 
Result so far: 112072.0
The remainder is 228 after subtracting 1632 from 1860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

Moving on to step 9:
816 goes into 2280 2 times with a remainder of 648.
Put 2 as the next digit of the answer. 
Result so far: 112072.2
If we subtract 1632 from 2280, we get 648.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6480, and continue the process.

Let's proceed to step 10:
The number 816 fits into 6480 7 times, leaving a remainder of 768.
Put 7 as the next digit of the answer. 
Result so far: 112072.27
Subtract 5712 from 6480 to get 768.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7680, and continue the process.

Moving on to step 11:
The number 816 fits into 7680 9 times, leaving a remainder of 336.
Write down 9 as next digit of the result. 
Result so far: 112072.279
Subtract 7344 from 7680 to get 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

Step 12:
816 can be fit into 3360 4 times, resulting in a remainder of 96.
Use 4 as the next digit of our solution. 
Result so far: 112072.2794
If we subtract 3264 from 3360, we get 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

On to step 13:
816 goes into 960 1 times with a remainder of 144.
The number 1 becomes the next digit in our result. 
Result so far: 112072.27941
Subtract 816 from 960 to get 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Advancing to step 14:
816 goes into 1440 1 times with a remainder of 624.
The number 1 becomes the next digit in our result. 
Result so far: 112072.279411
If we subtract 816 from 1440, we get 624.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6240, and continue the process.

The quotient of the division is 112072.279411, and the remainder is 6.24e-05.
