917907 ÷ 66 
We want to figure out the number of times 917907 can be divided by 66.

Moving on to step 1:
66 goes into 9 0 times with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Bring next digit (1) of the dividend behind the 9 and repeat the process: 91 / 66

On to step 2:
91 divided by 66 is 1 with a remainder of 25.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 66 from 91 and we're left with 25.
Grab the next digit (7) from the dividend, add it to 25, then carry on: 257 / 66

Going ahead to step 3:
If we divide 257 by 66, we get 3 and a remainder of 59.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
Subtract 198 from 257 to get 59.
Take the next digit (9) from the dividend and append it to 59, then repeat: 599 / 66

Let's proceed to step 4:
When dividing 599 by 66, we get 9 with a remainder of 5.
Write down 9 as next digit of the result. 
Result so far: 139.0
The remainder is 5 after subtracting 594 from 599.
Grab the next digit (0) from the dividend, add it to 5, then carry on: 50 / 66

Going ahead to step 5:
66 can be fit into 50 0 times, resulting in a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 1390.0
Deduct 0 from 50 and we're left with 50.
Append the next digit (7) from the dividend to 50 and continue with: 507 / 66

Going ahead to step 6:
66 can be fit into 507 7 times, resulting in a remainder of 45.
Write down 7 as next digit of the result. 
Result so far: 13907.0
Subtract 462 from 507 to get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Let's proceed to step 7:
450 divided by 66 is 6 with a remainder of 54.
Write down 6 as next digit of the result. 
Result so far: 13907.6
Deduct 396 from 450 and we're left 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.

On to step 8:
66 can be fit into 540 8 times, resulting in a remainder of 12.
Record the quotient 8 as the next digit in the result. 
Result so far: 13907.68
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.

Going ahead to step 9:
66 goes into 120 1 times with a remainder of 54.
Put 1 as the next digit of the answer. 
Result so far: 13907.681
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.

On to step 10:
66 can be fit into 540 8 times, resulting in a remainder of 12.
The next digit of our result is 8. 
Result so far: 13907.6818
Deduct 528 from 540 and we're left 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 11:
The number 66 fits into 120 1 times, leaving a remainder of 54.
Record the quotient 1 as the next digit in the result. 
Result so far: 13907.68181
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 12:
If we divide 540 by 66, we get 8 and a remainder of 12.
Put 8 as the next digit of the answer. 
Result so far: 13907.681818
Subtract 528 from 540 to 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.

Advancing to step 13:
66 goes into 120 1 times with a remainder of 54.
The next digit of our result is 1. 
Result so far: 13907.6818181
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.

On to step 14:
66 goes into 540 8 times with a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 13907.68181818
Subtract 528 from 540 to 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.

In conclusion, the division gives 13907.68181818 with a balance of 1.2e-08.
