We're dividing 66639296 by 939 
We want to divide 66639296 by 939.

Advancing to step 1:
When dividing 6 by 939, we get 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 939

Let's proceed to step 2:
When dividing 66 by 939, we get 0 with a remainder of 66.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 66 after subtracting 0 from 66.
Append the next digit (6) from the dividend to 66 and continue with: 666 / 939

Let's proceed to step 3:
939 goes into 666 0 times with a remainder of 666.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 666 and we're left with 666.
Append the next digit (3) from the dividend to 666 and continue with: 6663 / 939

Going ahead to step 4:
6663 divided by 939 is 7 with a remainder of 90.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Deduct 6573 from 6663 and we're left with 90.
Append the next digit (9) from the dividend to 90 and continue with: 909 / 939

Step 5:
909 divided by 939 is 0 with a remainder of 909.
The number 0 becomes the next digit in our result. 
Result so far: 70.0
If we subtract 0 from 909, we get 909.
Append the next digit (2) from the dividend to 909 and continue with: 9092 / 939

Going ahead to step 6:
939 goes into 9092 9 times with a remainder of 641.
Write down 9 as next digit of the result. 
Result so far: 709.0
Subtracting 8451 from 9092 leaves us with 641.
Bring next digit (9) of the dividend behind the 641 and repeat the process: 6419 / 939

On to step 7:
939 goes into 6419 6 times with a remainder of 785.
Put 6 as the next digit of the answer. 
Result so far: 7096.0
Deduct 5634 from 6419 and we're left with 785.
Fetch the next digit (6) from the dividend, attach it to 785 and continue: 7856 / 939

Step 8:
The number 939 fits into 7856 8 times, leaving a remainder of 344.
Record the quotient 8 as the next digit in the result. 
Result so far: 70968.0
Subtracting 7512 from 7856 leaves us with 344.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

Going ahead to step 9:
939 can be fit into 3440 3 times, resulting in a remainder of 623.
Write down 3 as next digit of the result. 
Result so far: 70968.3
If we subtract 2817 from 3440, we get 623.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6230, and continue the process.

Advancing to step 10:
When dividing 6230 by 939, we get 6 with a remainder of 596.
Put 6 as the next digit of the answer. 
Result so far: 70968.36
If we subtract 5634 from 6230, we get 596.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5960, and continue the process.

Let's proceed to step 11:
The number 939 fits into 5960 6 times, leaving a remainder of 326.
Use 6 as the next digit of our solution. 
Result so far: 70968.366
Subtracting 5634 from 5960 leaves us with 326.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3260, and continue the process.

The quotient of the division is 70968.366, and the remainder is 0.0326.
