We divide 658373 by 66
We want to figure out the number of times 658373 can be divided by 66.

On to step 1:
6 divided by 66 is 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Grab the next digit (5) from the dividend, add it to 6, then carry on: 65 / 66

Step 2:
66 can be fit into 65 0 times, resulting in a remainder of 65.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 65 to get 65.
Fetch the next digit (8) from the dividend, attach it to 65 and continue: 658 / 66

On to step 3:
66 goes into 658 9 times with a remainder of 64.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
The remainder is 64 after subtracting 594 from 658.
Bring next digit (3) of the dividend behind the 64 and repeat the process: 643 / 66

Going ahead to step 4:
66 goes into 643 9 times with a remainder of 49.
Use 9 as the next digit of our solution. 
Result so far: 99.0
Deduct 594 from 643 and we're left with 49.
Take the next digit (7) from the dividend and append it to 49, then repeat: 497 / 66

Going ahead to step 5:
66 goes into 497 7 times with a remainder of 35.
The number 7 becomes the next digit in our result. 
Result so far: 997.0
Deduct 462 from 497 and we're left with 35.
Take the next digit (3) from the dividend and append it to 35, then repeat: 353 / 66

Advancing to step 6:
If we divide 353 by 66, we get 5 and a remainder of 23.
The number 5 becomes the next digit in our result. 
Result so far: 9975.0
If we subtract 330 from 353, we get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

On to step 7:
66 goes into 230 3 times with a remainder of 32.
Put 3 as the next digit of the answer. 
Result so far: 9975.3
If we subtract 198 from 230, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 8:
When dividing 320 by 66, we get 4 with a remainder of 56.
The number 4 becomes the next digit in our result. 
Result so far: 9975.34
Deduct 264 from 320 and we're left with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Let's proceed to step 9:
The number 66 fits into 560 8 times, leaving a remainder of 32.
The number 8 becomes the next digit in our result. 
Result so far: 9975.348
If we take 528 away from 560, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 10:
66 can be fit into 320 4 times, resulting in a remainder of 56.
Use 4 as the next digit of our solution. 
Result so far: 9975.3484
If we take 264 away from 320, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Step 11:
When dividing 560 by 66, we get 8 with a remainder of 32.
Put 8 as the next digit of the answer. 
Result so far: 9975.34848
Subtract 528 from 560 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 12:
66 goes into 320 4 times with a remainder of 56.
Record the quotient 4 as the next digit in the result. 
Result so far: 9975.348484
Deduct 264 from 320 and we're left with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Let's proceed to step 13:
66 goes into 560 8 times with a remainder of 32.
The next digit of our result is 8. 
Result so far: 9975.3484848
If we subtract 528 from 560, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 14:
If we divide 320 by 66, we get 4 and a remainder of 56.
Write down 4 as next digit of the result. 
Result so far: 9975.34848484
Subtract 264 from 320 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

The final outcome is 9975.34848484, with a leftover of 5.6e-08.
