Let's divide 66716979 by 938
We want to figure out the number of times 66716979 can be divided by 938.

On to step 1:
938 can be fit into 6 0 times, resulting in a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 938

Step 2:
If we divide 66 by 938, we get 0 and a remainder of 66.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 66 leaves us with 66.
Include the next digit (7) from the dividend after 66, then repeat: 667 / 938

Let's proceed to step 3:
The number 938 fits into 667 0 times, leaving a remainder of 667.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 667 leaves us with 667.
Grab the next digit (1) from the dividend, add it to 667, then carry on: 6671 / 938

On to step 4:
If we divide 6671 by 938, we get 7 and a remainder of 105.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Subtract 6566 from 6671 to get 105.
Fetch the next digit (6) from the dividend, attach it to 105 and continue: 1056 / 938

On to step 5:
The number 938 fits into 1056 1 times, leaving a remainder of 118.
Write down 1 as next digit of the result. 
Result so far: 71.0
If we subtract 938 from 1056, we get 118.
Include the next digit (9) from the dividend after 118, then repeat: 1189 / 938

On to step 6:
938 can be fit into 1189 1 times, resulting in a remainder of 251.
Write down 1 as next digit of the result. 
Result so far: 711.0
The remainder is 251 after subtracting 938 from 1189.
Fetch the next digit (7) from the dividend, attach it to 251 and continue: 2517 / 938

Step 7:
938 can be fit into 2517 2 times, resulting in a remainder of 641.
Use 2 as the next digit of our solution. 
Result so far: 7112.0
Subtract 1876 from 2517 to get 641.
Grab the next digit (9) from the dividend, add it to 641, then carry on: 6419 / 938

Let's proceed to step 8:
938 can be fit into 6419 6 times, resulting in a remainder of 791.
The number 6 becomes the next digit in our result. 
Result so far: 71126.0
Subtract 5628 from 6419 to get 791.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7910, and continue the process.

Advancing to step 9:
938 goes into 7910 8 times with a remainder of 406.
Put 8 as the next digit of the answer. 
Result so far: 71126.8
If we take 7504 away from 7910, we end up with 406.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4060, and continue the process.

Going ahead to step 10:
4060 divided by 938 is 4 with a remainder of 308.
The next digit of our result is 4. 
Result so far: 71126.84
If we subtract 3752 from 4060, we get 308.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

Moving on to step 11:
3080 divided by 938 is 3 with a remainder of 266.
Record the quotient 3 as the next digit in the result. 
Result so far: 71126.843
If we subtract 2814 from 3080, we get 266.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2660, and continue the process.

On to step 12:
938 goes into 2660 2 times with a remainder of 784.
Write down 2 as next digit of the result. 
Result so far: 71126.8432
Deduct 1876 from 2660 and we're left with 784.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7840, and continue the process.

Advancing to step 13:
7840 divided by 938 is 8 with a remainder of 336.
Put 8 as the next digit of the answer. 
Result so far: 71126.84328
If we subtract 7504 from 7840, we get 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

Advancing to step 14:
938 can be fit into 3360 3 times, resulting in a remainder of 546.
Write down 3 as next digit of the result. 
Result so far: 71126.843283
If we subtract 2814 from 3360, we get 546.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5460, and continue the process.

On to step 15:
The number 938 fits into 5460 5 times, leaving a remainder of 770.
Write down 5 as next digit of the result. 
Result so far: 71126.8432835
If we take 4690 away from 5460, we end up with 770.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7700, and continue the process.

Moving on to step 16:
The number 938 fits into 7700 8 times, leaving a remainder of 196.
The next digit of our result is 8. 
Result so far: 71126.84328358
Deduct 7504 from 7700 and we're left with 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

After the division, we end up with 71126.84328358 and a remainder of 1.96e-07.
