We divide 38519420 by 21
Our goal is to divide 38519420 by 21.

Advancing to step 1:
If we divide 3 by 21, we get 0 and a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Take the next digit (8) from the dividend and append it to 3, then repeat: 38 / 21

Going ahead to step 2:
38 divided by 21 is 1 with a remainder of 17.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 17 after subtracting 21 from 38.
Grab the next digit (5) from the dividend, add it to 17, then carry on: 175 / 21

Moving on to step 3:
If we divide 175 by 21, we get 8 and a remainder of 7.
Put 8 as the next digit of the answer. 
Result so far: 18.0
The remainder is 7 after subtracting 168 from 175.
Grab the next digit (1) from the dividend, add it to 7, then carry on: 71 / 21

Let's proceed to step 4:
The number 21 fits into 71 3 times, leaving a remainder of 8.
Write down 3 as next digit of the result. 
Result so far: 183.0
Deduct 63 from 71 and we're left with 8.
Grab the next digit (9) from the dividend, add it to 8, then carry on: 89 / 21

Going ahead to step 5:
When dividing 89 by 21, we get 4 with a remainder of 5.
Put 4 as the next digit of the answer. 
Result so far: 1834.0
Subtracting 84 from 89 leaves us with 5.
Take the next digit (4) from the dividend and append it to 5, then repeat: 54 / 21

Advancing to step 6:
54 divided by 21 is 2 with a remainder of 12.
Write down 2 as next digit of the result. 
Result so far: 18342.0
Deduct 42 from 54 and we're left with 12.
Include the next digit (2) from the dividend after 12, then repeat: 122 / 21

Moving on to step 7:
The number 21 fits into 122 5 times, leaving a remainder of 17.
Record the quotient 5 as the next digit in the result. 
Result so far: 183425.0
The remainder is 17 after subtracting 105 from 122.
Bring next digit (0) of the dividend behind the 17 and repeat the process: 170 / 21

Going ahead to step 8:
When dividing 170 by 21, we get 8 with a remainder of 2.
Use 8 as the next digit of our solution. 
Result so far: 1834258.0
Deduct 168 from 170 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 9:
The number 21 fits into 20 0 times, leaving a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 1834258.0
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 10:
21 goes into 200 9 times with a remainder of 11.
Write down 9 as next digit of the result. 
Result so far: 1834258.09
Subtracting 189 from 200 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 11:
110 divided by 21 is 5 with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 1834258.095
If we take 105 away from 110, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 12:
21 goes into 50 2 times with a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 1834258.0952
Subtracting 42 from 50 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 13:
21 goes into 80 3 times with a remainder of 17.
The number 3 becomes the next digit in our result. 
Result so far: 1834258.09523
The remainder is 17 after subtracting 63 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 14:
The number 21 fits into 170 8 times, leaving a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 1834258.095238
If we subtract 168 from 170, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 15:
When dividing 20 by 21, we get 0 with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 1834258.095238
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 16:
200 divided by 21 is 9 with a remainder of 11.
The next digit of our result is 9. 
Result so far: 1834258.09523809
Subtract 189 from 200 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

The quotient of the division is 1834258.09523809, and the remainder is 1.1e-08.
