Let's divide 90789786 by 66
We want to figure out the number of times 90789786 can be divided by 66.

Advancing to step 1:
If we divide 9 by 66, we get 0 and a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Include the next digit (0) from the dividend after 9, then repeat: 90 / 66

Going ahead to step 2:
90 divided by 66 is 1 with a remainder of 24.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 66 away from 90, we end up with 24.
Include the next digit (7) from the dividend after 24, then repeat: 247 / 66

Let's proceed to step 3:
If we divide 247 by 66, we get 3 and a remainder of 49.
Use 3 as the next digit of our solution. 
Result so far: 13.0
If we subtract 198 from 247, we get 49.
Fetch the next digit (8) from the dividend, attach it to 49 and continue: 498 / 66

Going ahead to step 4:
When dividing 498 by 66, we get 7 with a remainder of 36.
Use 7 as the next digit of our solution. 
Result so far: 137.0
If we take 462 away from 498, we end up with 36.
Take the next digit (9) from the dividend and append it to 36, then repeat: 369 / 66

Let's proceed to step 5:
66 can be fit into 369 5 times, resulting in a remainder of 39.
The number 5 becomes the next digit in our result. 
Result so far: 1375.0
Deduct 330 from 369 and we're left with 39.
Grab the next digit (7) from the dividend, add it to 39, then carry on: 397 / 66

Let's proceed to step 6:
The number 66 fits into 397 6 times, leaving a remainder of 1.
Record the quotient 6 as the next digit in the result. 
Result so far: 13756.0
If we take 396 away from 397, we end up with 1.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 66

Going ahead to step 7:
The number 66 fits into 18 0 times, leaving a remainder of 18.
The next digit of our result is 0. 
Result so far: 137560.0
If we subtract 0 from 18, we get 18.
Include the next digit (6) from the dividend after 18, then repeat: 186 / 66

Advancing to step 8:
186 divided by 66 is 2 with a remainder of 54.
The number 2 becomes the next digit in our result. 
Result so far: 1375602.0
Subtract 132 from 186 to get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

On to step 9:
66 goes into 540 8 times with a remainder of 12.
Record the quotient 8 as the next digit in the result. 
Result so far: 1375602.8
If we take 528 away from 540, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 10:
120 divided by 66 is 1 with a remainder of 54.
Record the quotient 1 as the next digit in the result. 
Result so far: 1375602.81
If we subtract 66 from 120, we get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Going ahead to step 11:
540 divided by 66 is 8 with a remainder of 12.
Record the quotient 8 as the next digit in the result. 
Result so far: 1375602.818
Subtracting 528 from 540 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 12:
66 goes into 120 1 times with a remainder of 54.
The next digit of our result is 1. 
Result so far: 1375602.8181
Subtracting 66 from 120 leaves us with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Going ahead to step 13:
66 goes into 540 8 times with a remainder of 12.
Put 8 as the next digit of the answer. 
Result so far: 1375602.81818
If we subtract 528 from 540, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 14:
66 can be fit into 120 1 times, resulting in a remainder of 54.
The next digit of our result is 1. 
Result so far: 1375602.818181
If we take 66 away from 120, we end up with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Advancing to step 15:
If we divide 540 by 66, we get 8 and a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 1375602.8181818
Subtracting 528 from 540 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 16:
When dividing 120 by 66, we get 1 with a remainder of 54.
The number 1 becomes the next digit in our result. 
Result so far: 1375602.81818181
If we take 66 away from 120, we end up with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

The quotient of the division is 1375602.81818181, and the remainder is 5.4e-08.
