We're dividing 71391 by 74 
We want to figure out the number of times 71391 can be divided by 74.

On to step 1:
When dividing 7 by 74, we get 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Append the next digit (1) from the dividend to 7 and continue with: 71 / 74

On to step 2:
74 can be fit into 71 0 times, resulting in a remainder of 71.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 71 leaves us with 71.
Append the next digit (3) from the dividend to 71 and continue with: 713 / 74

Moving on to step 3:
If we divide 713 by 74, we get 9 and a remainder of 47.
The next digit of our result is 9. 
Result so far: 9.0
Deduct 666 from 713 and we're left with 47.
Append the next digit (9) from the dividend to 47 and continue with: 479 / 74

Let's proceed to step 4:
74 goes into 479 6 times with a remainder of 35.
The number 6 becomes the next digit in our result. 
Result so far: 96.0
If we subtract 444 from 479, we get 35.
Take the next digit (1) from the dividend and append it to 35, then repeat: 351 / 74

Let's proceed to step 5:
When dividing 351 by 74, we get 4 with a remainder of 55.
Use 4 as the next digit of our solution. 
Result so far: 964.0
The remainder is 55 after subtracting 296 from 351.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Moving on to step 6:
If we divide 550 by 74, we get 7 and a remainder of 32.
Write down 7 as next digit of the result. 
Result so far: 964.7
Subtracting 518 from 550 leaves us 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 7:
320 divided by 74 is 4 with a remainder of 24.
Record the quotient 4 as the next digit in the result. 
Result so far: 964.74
If we subtract 296 from 320, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 8:
240 divided by 74 is 3 with a remainder of 18.
Use 3 as the next digit of our solution. 
Result so far: 964.743
If we take 222 away from 240, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 9:
If we divide 180 by 74, we get 2 and a remainder of 32.
Write down 2 as next digit of the result. 
Result so far: 964.7432
Subtracting 148 from 180 leaves us 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.

Let's proceed to step 10:
320 divided by 74 is 4 with a remainder of 24.
The next digit of our result is 4. 
Result so far: 964.74324
Subtracting 296 from 320 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 11:
74 can be fit into 240 3 times, resulting in a remainder of 18.
Put 3 as the next digit of the answer. 
Result so far: 964.743243
Subtract 222 from 240 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 12:
The number 74 fits into 180 2 times, leaving a remainder of 32.
Put 2 as the next digit of the answer. 
Result so far: 964.7432432
If we take 148 away from 180, 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 13:
320 divided by 74 is 4 with a remainder of 24.
The number 4 becomes the next digit in our result. 
Result so far: 964.74324324
Deduct 296 from 320 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

The quotient of the division is 964.74324324, and the remainder is 2.4e-08.
