We look at the division of 21891011 by 930 
Let's see how many times 930 fits into 21891011.

Going ahead to step 1:
If we divide 2 by 930, we get 0 and a remainder of 2.
The next digit of our result is 0. 
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 / 930

On to step 2:
When dividing 21 by 930, we get 0 with a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 21, we end up with 21.
Bring next digit (8) of the dividend behind the 21 and repeat the process: 218 / 930

Let's proceed to step 3:
When dividing 218 by 930, we get 0 with a remainder of 218.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 218, we end up with 218.
Take the next digit (9) from the dividend and append it to 218, then repeat: 2189 / 930

Advancing to step 4:
If we divide 2189 by 930, we get 2 and a remainder of 329.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Deduct 1860 from 2189 and we're left with 329.
Bring next digit (1) of the dividend behind the 329 and repeat the process: 3291 / 930

Advancing to step 5:
930 can be fit into 3291 3 times, resulting in a remainder of 501.
Put 3 as the next digit of the answer. 
Result so far: 23.0
If we take 2790 away from 3291, we end up with 501.
Append the next digit (0) from the dividend to 501 and continue with: 5010 / 930

Step 6:
The number 930 fits into 5010 5 times, leaving a remainder of 360.
Record the quotient 5 as the next digit in the result. 
Result so far: 235.0
If we take 4650 away from 5010, we end up with 360.
Include the next digit (1) from the dividend after 360, then repeat: 3601 / 930

Step 7:
3601 divided by 930 is 3 with a remainder of 811.
The next digit of our result is 3. 
Result so far: 2353.0
If we subtract 2790 from 3601, we get 811.
Grab the next digit (1) from the dividend, add it to 811, then carry on: 8111 / 930

On to step 8:
930 goes into 8111 8 times with a remainder of 671.
The number 8 becomes the next digit in our result. 
Result so far: 23538.0
Subtracting 7440 from 8111 leaves us with 671.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6710, and continue the process.

Moving on to step 9:
930 can be fit into 6710 7 times, resulting in a remainder of 200.
The number 7 becomes the next digit in our result. 
Result so far: 23538.7
Subtracting 6510 from 6710 leaves us with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Step 10:
If we divide 2000 by 930, we get 2 and a remainder of 140.
Use 2 as the next digit of our solution. 
Result so far: 23538.72
Deduct 1860 from 2000 and we're left with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Let's proceed to step 11:
When dividing 1400 by 930, we get 1 with a remainder of 470.
Put 1 as the next digit of the answer. 
Result so far: 23538.721
If we take 930 away from 1400, we end up with 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4700, and continue the process.

On to step 12:
4700 divided by 930 is 5 with a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 23538.7215
Subtracting 4650 from 4700 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 13:
500 divided by 930 is 0 with a remainder of 500.
Record the quotient 0 as the next digit in the result. 
Result so far: 23538.7215
If we subtract 0 from 500, we get 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Let's proceed to step 14:
930 can be fit into 5000 5 times, resulting in a remainder of 350.
Put 5 as the next digit of the answer. 
Result so far: 23538.721505
The remainder is 350 after subtracting 4650 from 5000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Let's proceed to step 15:
930 goes into 3500 3 times with a remainder of 710.
Use 3 as the next digit of our solution. 
Result so far: 23538.7215053
Subtract 2790 from 3500 to get 710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7100, and continue the process.

Advancing to step 16:
When dividing 7100 by 930, we get 7 with a remainder of 590.
The number 7 becomes the next digit in our result. 
Result so far: 23538.72150537
If we take 6510 away from 7100, we end up with 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5900, and continue the process.

The final outcome is 23538.72150537, with a leftover of 5.9e-07.
