We're dividing 21370861 by 727 
We want to figure out the number of times 21370861 can be divided by 727.

Let's proceed to step 1:
727 goes into 2 0 times with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 727

Step 2:
When dividing 21 by 727, we get 0 with a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 21 to get 21.
Take the next digit (3) from the dividend and append it to 21, then repeat: 213 / 727

Moving on to step 3:
727 can be fit into 213 0 times, resulting in a remainder of 213.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 213 and we're left with 213.
Include the next digit (7) from the dividend after 213, then repeat: 2137 / 727

Advancing to step 4:
When dividing 2137 by 727, we get 2 with a remainder of 683.
The next digit of our result is 2. 
Result so far: 2.0
Deduct 1454 from 2137 and we're left with 683.
Fetch the next digit (0) from the dividend, attach it to 683 and continue: 6830 / 727

Advancing to step 5:
The number 727 fits into 6830 9 times, leaving a remainder of 287.
Record the quotient 9 as the next digit in the result. 
Result so far: 29.0
If we take 6543 away from 6830, we end up with 287.
Grab the next digit (8) from the dividend, add it to 287, then carry on: 2878 / 727

Advancing to step 6:
727 goes into 2878 3 times with a remainder of 697.
The next digit of our result is 3. 
Result so far: 293.0
If we subtract 2181 from 2878, we get 697.
Fetch the next digit (6) from the dividend, attach it to 697 and continue: 6976 / 727

Moving on to step 7:
If we divide 6976 by 727, we get 9 and a remainder of 433.
The number 9 becomes the next digit in our result. 
Result so far: 2939.0
If we take 6543 away from 6976, we end up with 433.
Bring next digit (1) of the dividend behind the 433 and repeat the process: 4331 / 727

On to step 8:
4331 divided by 727 is 5 with a remainder of 696.
Record the quotient 5 as the next digit in the result. 
Result so far: 29395.0
The remainder is 696 after subtracting 3635 from 4331.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6960, and continue the process.

Advancing to step 9:
When dividing 6960 by 727, we get 9 with a remainder of 417.
Write down 9 as next digit of the result. 
Result so far: 29395.9
If we subtract 6543 from 6960, we get 417.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4170, and continue the process.

On to step 10:
727 can be fit into 4170 5 times, resulting in a remainder of 535.
Record the quotient 5 as the next digit in the result. 
Result so far: 29395.95
The remainder is 535 after subtracting 3635 from 4170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5350, and continue the process.

Advancing to step 11:
727 goes into 5350 7 times with a remainder of 261.
Record the quotient 7 as the next digit in the result. 
Result so far: 29395.957
If we subtract 5089 from 5350, we get 261.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2610, and continue the process.

On to step 12:
If we divide 2610 by 727, we get 3 and a remainder of 429.
Use 3 as the next digit of our solution. 
Result so far: 29395.9573
Subtract 2181 from 2610 to get 429.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4290, and continue the process.

Moving on to step 13:
727 goes into 4290 5 times with a remainder of 655.
The next digit of our result is 5. 
Result so far: 29395.95735
Subtract 3635 from 4290 to get 655.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6550, and continue the process.

Advancing to step 14:
If we divide 6550 by 727, we get 9 and a remainder of 7.
Put 9 as the next digit of the answer. 
Result so far: 29395.957359
Subtracting 6543 from 6550 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 15:
When dividing 70 by 727, we get 0 with a remainder of 70.
Write down 0 as next digit of the result. 
Result so far: 29395.957359
If we subtract 0 from 70, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 16:
727 goes into 700 0 times with a remainder of 700.
Use 0 as the next digit of our solution. 
Result so far: 29395.957359
Subtract 0 from 700 to get 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

The final outcome is 29395.957359, with a leftover of 7e-07.
