We look at the division of 21098404 by 507 
We want to divide 21098404 by 507.

Advancing to step 1:
When dividing 2 by 507, we get 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 507

Let's proceed to step 2:
When dividing 21 by 507, we get 0 with a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 21 leaves us with 21.
Append the next digit (0) from the dividend to 21 and continue with: 210 / 507

Moving on to step 3:
The number 507 fits into 210 0 times, leaving a remainder of 210.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 210 and we're left with 210.
Grab the next digit (9) from the dividend, add it to 210, then carry on: 2109 / 507

Let's proceed to step 4:
If we divide 2109 by 507, we get 4 and a remainder of 81.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtracting 2028 from 2109 leaves us with 81.
Include the next digit (8) from the dividend after 81, then repeat: 818 / 507

Moving on to step 5:
The number 507 fits into 818 1 times, leaving a remainder of 311.
Record the quotient 1 as the next digit in the result. 
Result so far: 41.0
Subtracting 507 from 818 leaves us with 311.
Grab the next digit (4) from the dividend, add it to 311, then carry on: 3114 / 507

On to step 6:
507 can be fit into 3114 6 times, resulting in a remainder of 72.
The next digit of our result is 6. 
Result so far: 416.0
If we subtract 3042 from 3114, we get 72.
Fetch the next digit (0) from the dividend, attach it to 72 and continue: 720 / 507

On to step 7:
If we divide 720 by 507, we get 1 and a remainder of 213.
Record the quotient 1 as the next digit in the result. 
Result so far: 4161.0
Subtracting 507 from 720 leaves us with 213.
Append the next digit (4) from the dividend to 213 and continue with: 2134 / 507

Let's proceed to step 8:
2134 divided by 507 is 4 with a remainder of 106.
The number 4 becomes the next digit in our result. 
Result so far: 41614.0
The remainder is 106 after subtracting 2028 from 2134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

On to step 9:
If we divide 1060 by 507, we get 2 and a remainder of 46.
The next digit of our result is 2. 
Result so far: 41614.2
Deduct 1014 from 1060 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Going ahead to step 10:
460 divided by 507 is 0 with a remainder of 460.
Use 0 as the next digit of our solution. 
Result so far: 41614.2
Subtracting 0 from 460 leaves us with 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Moving on to step 11:
4600 divided by 507 is 9 with a remainder of 37.
The number 9 becomes the next digit in our result. 
Result so far: 41614.209
Subtracting 4563 from 4600 leaves us with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Advancing to step 12:
If we divide 370 by 507, we get 0 and a remainder of 370.
Write down 0 as next digit of the result. 
Result so far: 41614.209
Subtracting 0 from 370 leaves us with 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

Advancing to step 13:
The number 507 fits into 3700 7 times, leaving a remainder of 151.
The number 7 becomes the next digit in our result. 
Result so far: 41614.20907
The remainder is 151 after subtracting 3549 from 3700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1510, and continue the process.

On to step 14:
The number 507 fits into 1510 2 times, leaving a remainder of 496.
Write down 2 as next digit of the result. 
Result so far: 41614.209072
If we take 1014 away from 1510, we end up with 496.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4960, and continue the process.

Going ahead to step 15:
The number 507 fits into 4960 9 times, leaving a remainder of 397.
The number 9 becomes the next digit in our result. 
Result so far: 41614.2090729
Subtracting 4563 from 4960 leaves us with 397.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3970, and continue the process.

Let's proceed to step 16:
The number 507 fits into 3970 7 times, leaving a remainder of 421.
The number 7 becomes the next digit in our result. 
Result so far: 41614.20907297
If we subtract 3549 from 3970, we get 421.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4210, and continue the process.

The quotient of the division is 41614.20907297, and the remainder is 4.21e-07.
