Let's divide 91799585 by 66
We want to figure out the number of times 91799585 can be divided by 66.

On to step 1:
The number 66 fits into 9 0 times, leaving a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Include the next digit (1) from the dividend after 9, then repeat: 91 / 66

Advancing to step 2:
The number 66 fits into 91 1 times, leaving a remainder of 25.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 66 from 91, we get 25.
Grab the next digit (7) from the dividend, add it to 25, then carry on: 257 / 66

Advancing to step 3:
66 can be fit into 257 3 times, resulting in a remainder of 59.
The next digit of our result is 3. 
Result so far: 13.0
The remainder is 59 after subtracting 198 from 257.
Grab the next digit (9) from the dividend, add it to 59, then carry on: 599 / 66

On to step 4:
599 divided by 66 is 9 with a remainder of 5.
Write down 9 as next digit of the result. 
Result so far: 139.0
Subtract 594 from 599 to get 5.
Fetch the next digit (9) from the dividend, attach it to 5 and continue: 59 / 66

Step 5:
The number 66 fits into 59 0 times, leaving a remainder of 59.
The next digit of our result is 0. 
Result so far: 1390.0
The remainder is 59 after subtracting 0 from 59.
Take the next digit (5) from the dividend and append it to 59, then repeat: 595 / 66

On to step 6:
66 goes into 595 9 times with a remainder of 1.
The next digit of our result is 9. 
Result so far: 13909.0
Deduct 594 from 595 and we're left with 1.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 66

On to step 7:
The number 66 fits into 18 0 times, leaving a remainder of 18.
Put 0 as the next digit of the answer. 
Result so far: 139090.0
Subtract 0 from 18 to get 18.
Bring next digit (5) of the dividend behind the 18 and repeat the process: 185 / 66

Step 8:
66 goes into 185 2 times with a remainder of 53.
Write down 2 as next digit of the result. 
Result so far: 1390902.0
Subtract 132 from 185 to get 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Step 9:
66 goes into 530 8 times with a remainder of 2.
The next digit of our result is 8. 
Result so far: 1390902.8
If we take 528 away from 530, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 10:
20 divided by 66 is 0 with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 1390902.8
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 11:
200 divided by 66 is 3 with a remainder of 2.
The next digit of our result is 3. 
Result so far: 1390902.803
If we take 198 away from 200, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 12:
If we divide 20 by 66, we get 0 and a remainder of 20.
The next digit of our result is 0. 
Result so far: 1390902.803
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 13:
66 can be fit into 200 3 times, resulting in a remainder of 2.
Write down 3 as next digit of the result. 
Result so far: 1390902.80303
If we subtract 198 from 200, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 14:
66 can be fit into 20 0 times, resulting in a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 1390902.80303
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 15:
If we divide 200 by 66, we get 3 and a remainder of 2.
Record the quotient 3 as the next digit in the result. 
Result so far: 1390902.8030303
The remainder is 2 after subtracting 198 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 16:
When dividing 20 by 66, we get 0 with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 1390902.8030303
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final outcome is 1390902.8030303, with a leftover of 2e-08.
