We're dividing 74066151 by 939 
Let's see how many times 939 fits into 74066151.

Step 1:
If we divide 7 by 939, we get 0 and a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Grab the next digit (4) from the dividend, add it to 7, then carry on: 74 / 939

Going ahead to step 2:
74 divided by 939 is 0 with a remainder of 74.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 74, we get 74.
Bring next digit (0) of the dividend behind the 74 and repeat the process: 740 / 939

Let's proceed to step 3:
740 divided by 939 is 0 with a remainder of 740.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 740 after subtracting 0 from 740.
Grab the next digit (6) from the dividend, add it to 740, then carry on: 7406 / 939

Going ahead to step 4:
7406 divided by 939 is 7 with a remainder of 833.
Write down 7 as next digit of the result. 
Result so far: 7.0
The remainder is 833 after subtracting 6573 from 7406.
Grab the next digit (6) from the dividend, add it to 833, then carry on: 8336 / 939

Advancing to step 5:
When dividing 8336 by 939, we get 8 with a remainder of 824.
The number 8 becomes the next digit in our result. 
Result so far: 78.0
If we take 7512 away from 8336, we end up with 824.
Include the next digit (1) from the dividend after 824, then repeat: 8241 / 939

On to step 6:
The number 939 fits into 8241 8 times, leaving a remainder of 729.
The next digit of our result is 8. 
Result so far: 788.0
If we subtract 7512 from 8241, we get 729.
Bring next digit (5) of the dividend behind the 729 and repeat the process: 7295 / 939

Going ahead to step 7:
If we divide 7295 by 939, we get 7 and a remainder of 722.
Write down 7 as next digit of the result. 
Result so far: 7887.0
The remainder is 722 after subtracting 6573 from 7295.
Bring next digit (1) of the dividend behind the 722 and repeat the process: 7221 / 939

Going ahead to step 8:
When dividing 7221 by 939, we get 7 with a remainder of 648.
The next digit of our result is 7. 
Result so far: 78877.0
Subtracting 6573 from 7221 leaves us with 648.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6480, and continue the process.

Let's proceed to step 9:
If we divide 6480 by 939, we get 6 and a remainder of 846.
Write down 6 as next digit of the result. 
Result so far: 78877.6
Deduct 5634 from 6480 and we're left with 846.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8460, and continue the process.

Step 10:
If we divide 8460 by 939, we get 9 and a remainder of 9.
Record the quotient 9 as the next digit in the result. 
Result so far: 78877.69
If we subtract 8451 from 8460, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 11:
If we divide 90 by 939, we get 0 and a remainder of 90.
Record the quotient 0 as the next digit in the result. 
Result so far: 78877.69
Subtract 0 from 90 to get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Advancing to step 12:
939 goes into 900 0 times with a remainder of 900.
Use 0 as the next digit of our solution. 
Result so far: 78877.69
Subtract 0 from 900 to get 900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9000, and continue the process.

In conclusion, the division gives 78877.69 with a balance of 0.009.
