We look at the division of 90814759 by 66 
We want to divide 90814759 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.
Bring next digit (0) of the dividend behind the 9 and repeat the process: 90 / 66

On to step 2:
If we divide 90 by 66, we get 1 and a remainder of 24.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 66 from 90, we get 24.
Grab the next digit (8) from the dividend, add it to 24, then carry on: 248 / 66

Let's proceed to step 3:
248 divided by 66 is 3 with a remainder of 50.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
Subtract 198 from 248 to get 50.
Fetch the next digit (1) from the dividend, attach it to 50 and continue: 501 / 66

On to step 4:
When dividing 501 by 66, we get 7 with a remainder of 39.
The number 7 becomes the next digit in our result. 
Result so far: 137.0
Subtract 462 from 501 to get 39.
Grab the next digit (4) from the dividend, add it to 39, then carry on: 394 / 66

Let's proceed to step 5:
66 can be fit into 394 5 times, resulting in a remainder of 64.
Use 5 as the next digit of our solution. 
Result so far: 1375.0
The remainder is 64 after subtracting 330 from 394.
Take the next digit (7) from the dividend and append it to 64, then repeat: 647 / 66

Moving on to step 6:
66 can be fit into 647 9 times, resulting in a remainder of 53.
Record the quotient 9 as the next digit in the result. 
Result so far: 13759.0
The remainder is 53 after subtracting 594 from 647.
Include the next digit (5) from the dividend after 53, then repeat: 535 / 66

Going ahead to step 7:
535 divided by 66 is 8 with a remainder of 7.
Put 8 as the next digit of the answer. 
Result so far: 137598.0
The remainder is 7 after subtracting 528 from 535.
Grab the next digit (9) from the dividend, add it to 7, then carry on: 79 / 66

Let's proceed to step 8:
66 can be fit into 79 1 times, resulting in a remainder of 13.
The next digit of our result is 1. 
Result so far: 1375981.0
Subtracting 66 from 79 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 9:
If we divide 130 by 66, we get 1 and a remainder of 64.
Write down 1 as next digit of the result. 
Result so far: 1375981.1
Subtract 66 from 130 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 10:
If we divide 640 by 66, we get 9 and a remainder of 46.
Use 9 as the next digit of our solution. 
Result so far: 1375981.19
Subtract 594 from 640 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Moving on to step 11:
When dividing 460 by 66, we get 6 with a remainder of 64.
Write down 6 as next digit of the result. 
Result so far: 1375981.196
If we take 396 away from 460, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 12:
The number 66 fits into 640 9 times, leaving a remainder of 46.
Write down 9 as next digit of the result. 
Result so far: 1375981.1969
Subtracting 594 from 640 leaves us with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Let's proceed to step 13:
66 goes into 460 6 times with a remainder of 64.
Write down 6 as next digit of the result. 
Result so far: 1375981.19696
Deduct 396 from 460 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 14:
66 goes into 640 9 times with a remainder of 46.
Use 9 as the next digit of our solution. 
Result so far: 1375981.196969
If we take 594 away from 640, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Step 15:
If we divide 460 by 66, we get 6 and a remainder of 64.
The next digit of our result is 6. 
Result so far: 1375981.1969696
If we subtract 396 from 460, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Advancing to step 16:
The number 66 fits into 640 9 times, leaving a remainder of 46.
The next digit of our result is 9. 
Result so far: 1375981.19696969
If we take 594 away from 640, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

The final result is 1375981.19696969 with a remainder of 4.6e-08.
