We look at the division of 21420009 by 930 
We want to divide 21420009 by 930.

Moving on to step 1:
930 can be fit into 2 0 times, resulting in a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 930

Going ahead to step 2:
930 can be fit into 21 0 times, resulting in a remainder of 21.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 21, we end up with 21.
Fetch the next digit (4) from the dividend, attach it to 21 and continue: 214 / 930

Let's proceed to step 3:
If we divide 214 by 930, we get 0 and a remainder of 214.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 214 leaves us with 214.
Append the next digit (2) from the dividend to 214 and continue with: 2142 / 930

Advancing to step 4:
930 can be fit into 2142 2 times, resulting in a remainder of 282.
The next digit of our result is 2. 
Result so far: 2.0
Deduct 1860 from 2142 and we're left with 282.
Grab the next digit (0) from the dividend, add it to 282, then carry on: 2820 / 930

Advancing to step 5:
930 can be fit into 2820 3 times, resulting in a remainder of 30.
The number 3 becomes the next digit in our result. 
Result so far: 23.0
Subtract 2790 from 2820 to get 30.
Include the next digit (0) from the dividend after 30, then repeat: 300 / 930

Moving on to step 6:
The number 930 fits into 300 0 times, leaving a remainder of 300.
Use 0 as the next digit of our solution. 
Result so far: 230.0
If we take 0 away from 300, we end up with 300.
Grab the next digit (0) from the dividend, add it to 300, then carry on: 3000 / 930

On to step 7:
If we divide 3000 by 930, we get 3 and a remainder of 210.
Record the quotient 3 as the next digit in the result. 
Result so far: 2303.0
The remainder is 210 after subtracting 2790 from 3000.
Bring next digit (9) of the dividend behind the 210 and repeat the process: 2109 / 930

Moving on to step 8:
The number 930 fits into 2109 2 times, leaving a remainder of 249.
The next digit of our result is 2. 
Result so far: 23032.0
Subtracting 1860 from 2109 leaves us with 249.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2490, and continue the process.

On to step 9:
When dividing 2490 by 930, we get 2 with a remainder of 630.
The number 2 becomes the next digit in our result. 
Result so far: 23032.2
The remainder is 630 after subtracting 1860 from 2490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6300, and continue the process.

Advancing to step 10:
6300 divided by 930 is 6 with a remainder of 720.
Put 6 as the next digit of the answer. 
Result so far: 23032.26
The remainder is 720 after subtracting 5580 from 6300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7200, and continue the process.

Step 11:
When dividing 7200 by 930, we get 7 with a remainder of 690.
The number 7 becomes the next digit in our result. 
Result so far: 23032.267
If we take 6510 away from 7200, we end up with 690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6900, and continue the process.

Moving on to step 12:
6900 divided by 930 is 7 with a remainder of 390.
Write down 7 as next digit of the result. 
Result so far: 23032.2677
If we take 6510 away from 6900, we end up with 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

The quotient of the division is 23032.2677, and the remainder is 0.0039.
