We look at the division of 20921211 by 731 
We're looking to find how many times 731 goes into 20921211.

Let's proceed to step 1:
731 can be fit into 2 0 times, resulting in a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 731

Advancing to step 2:
731 can be fit into 20 0 times, resulting in a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 20 leaves us with 20.
Take the next digit (9) from the dividend and append it to 20, then repeat: 209 / 731

On to step 3:
731 goes into 209 0 times with a remainder of 209.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 209 leaves us with 209.
Fetch the next digit (2) from the dividend, attach it to 209 and continue: 2092 / 731

Let's proceed to step 4:
731 goes into 2092 2 times with a remainder of 630.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we take 1462 away from 2092, we end up with 630.
Fetch the next digit (1) from the dividend, attach it to 630 and continue: 6301 / 731

Going ahead to step 5:
6301 divided by 731 is 8 with a remainder of 453.
Write down 8 as next digit of the result. 
Result so far: 28.0
Subtracting 5848 from 6301 leaves us with 453.
Grab the next digit (2) from the dividend, add it to 453, then carry on: 4532 / 731

Going ahead to step 6:
The number 731 fits into 4532 6 times, leaving a remainder of 146.
Use 6 as the next digit of our solution. 
Result so far: 286.0
If we take 4386 away from 4532, we end up with 146.
Include the next digit (1) from the dividend after 146, then repeat: 1461 / 731

Step 7:
If we divide 1461 by 731, we get 1 and a remainder of 730.
Record the quotient 1 as the next digit in the result. 
Result so far: 2861.0
Subtracting 731 from 1461 leaves us with 730.
Fetch the next digit (1) from the dividend, attach it to 730 and continue: 7301 / 731

Moving on to step 8:
731 goes into 7301 9 times with a remainder of 722.
Use 9 as the next digit of our solution. 
Result so far: 28619.0
Deduct 6579 from 7301 and we're left with 722.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7220, and continue the process.

Step 9:
The number 731 fits into 7220 9 times, leaving a remainder of 641.
The number 9 becomes the next digit in our result. 
Result so far: 28619.9
Subtracting 6579 from 7220 leaves us with 641.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6410, and continue the process.

Going ahead to step 10:
If we divide 6410 by 731, we get 8 and a remainder of 562.
Put 8 as the next digit of the answer. 
Result so far: 28619.98
Subtract 5848 from 6410 to get 562.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5620, and continue the process.

Going ahead to step 11:
When dividing 5620 by 731, we get 7 with a remainder of 503.
The next digit of our result is 7. 
Result so far: 28619.987
If we take 5117 away from 5620, we end up with 503.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5030, and continue the process.

Moving on to step 12:
731 goes into 5030 6 times with a remainder of 644.
Record the quotient 6 as the next digit in the result. 
Result so far: 28619.9876
If we subtract 4386 from 5030, we get 644.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6440, and continue the process.

Let's proceed to step 13:
If we divide 6440 by 731, we get 8 and a remainder of 592.
Record the quotient 8 as the next digit in the result. 
Result so far: 28619.98768
Subtracting 5848 from 6440 leaves us with 592.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5920, and continue the process.

Going ahead to step 14:
731 goes into 5920 8 times with a remainder of 72.
Put 8 as the next digit of the answer. 
Result so far: 28619.987688
Subtract 5848 from 5920 to get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

The final outcome is 28619.987688, with a leftover of 7.2e-06.
