We look at the division of 637290 by 66 
We want to figure out the number of times 637290 can be divided by 66.

Advancing to step 1:
66 can be fit into 6 0 times, resulting in a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Take the next digit (3) from the dividend and append it to 6, then repeat: 63 / 66

Step 2:
The number 66 fits into 63 0 times, leaving a remainder of 63.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 63, we end up with 63.
Fetch the next digit (7) from the dividend, attach it to 63 and continue: 637 / 66

Let's proceed to step 3:
If we divide 637 by 66, we get 9 and a remainder of 43.
The next digit of our result is 9. 
Result so far: 9.0
Subtract 594 from 637 to get 43.
Grab the next digit (2) from the dividend, add it to 43, then carry on: 432 / 66

Advancing to step 4:
The number 66 fits into 432 6 times, leaving a remainder of 36.
Record the quotient 6 as the next digit in the result. 
Result so far: 96.0
Deduct 396 from 432 and we're left with 36.
Append the next digit (9) from the dividend to 36 and continue with: 369 / 66

Moving on to step 5:
66 goes into 369 5 times with a remainder of 39.
Put 5 as the next digit of the answer. 
Result so far: 965.0
The remainder is 39 after subtracting 330 from 369.
Bring next digit (0) of the dividend behind the 39 and repeat the process: 390 / 66

Step 6:
66 goes into 390 5 times with a remainder of 60.
Use 5 as the next digit of our solution. 
Result so far: 9655.0
Subtracting 330 from 390 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 7:
If we divide 600 by 66, we get 9 and a remainder of 6.
Record the quotient 9 as the next digit in the result. 
Result so far: 9655.9
Deduct 594 from 600 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 8:
66 can be fit into 60 0 times, resulting in a remainder of 60.
Put 0 as the next digit of the answer. 
Result so far: 9655.9
If we subtract 0 from 60, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 9:
66 can be fit into 600 9 times, resulting in a remainder of 6.
Write down 9 as next digit of the result. 
Result so far: 9655.909
If we take 594 away from 600, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 10:
66 can be fit into 60 0 times, resulting in a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 9655.909
Subtract 0 from 60 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 11:
If we divide 600 by 66, we get 9 and a remainder of 6.
Put 9 as the next digit of the answer. 
Result so far: 9655.90909
If we subtract 594 from 600, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 12:
When dividing 60 by 66, we get 0 with a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 9655.90909
If we subtract 0 from 60, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 13:
The number 66 fits into 600 9 times, leaving a remainder of 6.
The next digit of our result is 9. 
Result so far: 9655.9090909
Subtract 594 from 600 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 14:
If we divide 60 by 66, we get 0 and a remainder of 60.
The next digit of our result is 0. 
Result so far: 9655.9090909
The remainder is 60 after subtracting 0 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

In conclusion, the division gives 9655.9090909 with a balance of 6e-08.
