We look at the division of 921123 by 71 
We want to figure out the number of times 921123 can be divided by 71.

Moving on to step 1:
The number 71 fits into 9 0 times, leaving a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Include the next digit (2) from the dividend after 9, then repeat: 92 / 71

Going ahead to step 2:
If we divide 92 by 71, we get 1 and a remainder of 21.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 71 from 92 leaves us with 21.
Fetch the next digit (1) from the dividend, attach it to 21 and continue: 211 / 71

Step 3:
211 divided by 71 is 2 with a remainder of 69.
Write down 2 as next digit of the result. 
Result so far: 12.0
The remainder is 69 after subtracting 142 from 211.
Grab the next digit (1) from the dividend, add it to 69, then carry on: 691 / 71

Step 4:
If we divide 691 by 71, we get 9 and a remainder of 52.
Write down 9 as next digit of the result. 
Result so far: 129.0
If we take 639 away from 691, we end up with 52.
Take the next digit (2) from the dividend and append it to 52, then repeat: 522 / 71

On to step 5:
If we divide 522 by 71, we get 7 and a remainder of 25.
Record the quotient 7 as the next digit in the result. 
Result so far: 1297.0
If we subtract 497 from 522, we get 25.
Fetch the next digit (3) from the dividend, attach it to 25 and continue: 253 / 71

Advancing to step 6:
The number 71 fits into 253 3 times, leaving a remainder of 40.
The next digit of our result is 3. 
Result so far: 12973.0
Subtracting 213 from 253 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 7:
When dividing 400 by 71, we get 5 with a remainder of 45.
Record the quotient 5 as the next digit in the result. 
Result so far: 12973.5
Subtracting 355 from 400 leaves us with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Advancing to step 8:
If we divide 450 by 71, we get 6 and a remainder of 24.
Record the quotient 6 as the next digit in the result. 
Result so far: 12973.56
Deduct 426 from 450 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.

Let's proceed to step 9:
The number 71 fits into 240 3 times, leaving a remainder of 27.
The next digit of our result is 3. 
Result so far: 12973.563
Deduct 213 from 240 and we're left with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Going ahead to step 10:
When dividing 270 by 71, we get 3 with a remainder of 57.
The number 3 becomes the next digit in our result. 
Result so far: 12973.5633
Subtract 213 from 270 to get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

After the division, we end up with 12973.5633 and a remainder of 0.00057.
