We look at the division of 21011842 by 712 
We want to figure out the number of times 21011842 can be divided by 712.

Step 1:
712 goes into 2 0 times with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 712

Moving on to step 2:
712 goes into 21 0 times with a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 21, we end up with 21.
Include the next digit (0) from the dividend after 21, then repeat: 210 / 712

Going ahead to step 3:
If we divide 210 by 712, we get 0 and a remainder of 210.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 210 to get 210.
Append the next digit (1) from the dividend to 210 and continue with: 2101 / 712

On to step 4:
When dividing 2101 by 712, we get 2 with a remainder of 677.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we take 1424 away from 2101, we end up with 677.
Bring next digit (1) of the dividend behind the 677 and repeat the process: 6771 / 712

Moving on to step 5:
The number 712 fits into 6771 9 times, leaving a remainder of 363.
The number 9 becomes the next digit in our result. 
Result so far: 29.0
The remainder is 363 after subtracting 6408 from 6771.
Fetch the next digit (8) from the dividend, attach it to 363 and continue: 3638 / 712

Going ahead to step 6:
When dividing 3638 by 712, we get 5 with a remainder of 78.
The next digit of our result is 5. 
Result so far: 295.0
Subtract 3560 from 3638 to get 78.
Grab the next digit (4) from the dividend, add it to 78, then carry on: 784 / 712

Moving on to step 7:
If we divide 784 by 712, we get 1 and a remainder of 72.
Record the quotient 1 as the next digit in the result. 
Result so far: 2951.0
Subtracting 712 from 784 leaves us with 72.
Fetch the next digit (2) from the dividend, attach it to 72 and continue: 722 / 712

Advancing to step 8:
712 goes into 722 1 times with a remainder of 10.
Write down 1 as next digit of the result. 
Result so far: 29511.0
Subtract 712 from 722 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 9:
712 can be fit into 100 0 times, resulting in a remainder of 100.
Put 0 as the next digit of the answer. 
Result so far: 29511.0
If we subtract 0 from 100, we get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Let's proceed to step 10:
The number 712 fits into 1000 1 times, leaving a remainder of 288.
Use 1 as the next digit of our solution. 
Result so far: 29511.01
If we subtract 712 from 1000, we get 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Step 11:
If we divide 2880 by 712, we get 4 and a remainder of 32.
The number 4 becomes the next digit in our result. 
Result so far: 29511.014
Subtracting 2848 from 2880 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.

Step 12:
If we divide 320 by 712, we get 0 and a remainder of 320.
Record the quotient 0 as the next digit in the result. 
Result so far: 29511.014
If we subtract 0 from 320, we get 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Advancing to step 13:
712 can be fit into 3200 4 times, resulting in a remainder of 352.
Record the quotient 4 as the next digit in the result. 
Result so far: 29511.01404
Subtracting 2848 from 3200 leaves us with 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

Advancing to step 14:
3520 divided by 712 is 4 with a remainder of 672.
The number 4 becomes the next digit in our result. 
Result so far: 29511.014044
Subtracting 2848 from 3520 leaves us with 672.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6720, and continue the process.

The final outcome is 29511.014044, with a leftover of 6.72e-05.
