Let's divide 21673086 by 453
Let's see how many times 453 fits into 21673086.

Step 1:
453 goes into 2 0 times with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 453

Going ahead to step 2:
If we divide 21 by 453, we get 0 and a remainder of 21.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 21, we end up with 21.
Bring next digit (6) of the dividend behind the 21 and repeat the process: 216 / 453

Advancing to step 3:
If we divide 216 by 453, we get 0 and a remainder of 216.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 216 leaves us with 216.
Include the next digit (7) from the dividend after 216, then repeat: 2167 / 453

Moving on to step 4:
The number 453 fits into 2167 4 times, leaving a remainder of 355.
Write down 4 as next digit of the result. 
Result so far: 4.0
The remainder is 355 after subtracting 1812 from 2167.
Grab the next digit (3) from the dividend, add it to 355, then carry on: 3553 / 453

Moving on to step 5:
453 can be fit into 3553 7 times, resulting in a remainder of 382.
Use 7 as the next digit of our solution. 
Result so far: 47.0
If we take 3171 away from 3553, we end up with 382.
Append the next digit (0) from the dividend to 382 and continue with: 3820 / 453

Advancing to step 6:
453 can be fit into 3820 8 times, resulting in a remainder of 196.
The number 8 becomes the next digit in our result. 
Result so far: 478.0
The remainder is 196 after subtracting 3624 from 3820.
Append the next digit (8) from the dividend to 196 and continue with: 1968 / 453

Advancing to step 7:
1968 divided by 453 is 4 with a remainder of 156.
The next digit of our result is 4. 
Result so far: 4784.0
If we take 1812 away from 1968, we end up with 156.
Bring next digit (6) of the dividend behind the 156 and repeat the process: 1566 / 453

On to step 8:
453 can be fit into 1566 3 times, resulting in a remainder of 207.
The next digit of our result is 3. 
Result so far: 47843.0
The remainder is 207 after subtracting 1359 from 1566.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2070, and continue the process.

Going ahead to step 9:
The number 453 fits into 2070 4 times, leaving a remainder of 258.
The number 4 becomes the next digit in our result. 
Result so far: 47843.4
Deduct 1812 from 2070 and we're left with 258.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2580, and continue the process.

Let's proceed to step 10:
If we divide 2580 by 453, we get 5 and a remainder of 315.
Record the quotient 5 as the next digit in the result. 
Result so far: 47843.45
The remainder is 315 after subtracting 2265 from 2580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3150, and continue the process.

Advancing to step 11:
3150 divided by 453 is 6 with a remainder of 432.
Record the quotient 6 as the next digit in the result. 
Result so far: 47843.456
If we subtract 2718 from 3150, we get 432.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4320, and continue the process.

Step 12:
453 can be fit into 4320 9 times, resulting in a remainder of 243.
Use 9 as the next digit of our solution. 
Result so far: 47843.4569
Deduct 4077 from 4320 and we're left with 243.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2430, and continue the process.

Advancing to step 13:
If we divide 2430 by 453, we get 5 and a remainder of 165.
Record the quotient 5 as the next digit in the result. 
Result so far: 47843.45695
If we take 2265 away from 2430, we end up with 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

Advancing to step 14:
When dividing 1650 by 453, we get 3 with a remainder of 291.
Write down 3 as next digit of the result. 
Result so far: 47843.456953
The remainder is 291 after subtracting 1359 from 1650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2910, and continue the process.

Advancing to step 15:
453 goes into 2910 6 times with a remainder of 192.
Use 6 as the next digit of our solution. 
Result so far: 47843.4569536
Deduct 2718 from 2910 and we're left with 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

On to step 16:
1920 divided by 453 is 4 with a remainder of 108.
Use 4 as the next digit of our solution. 
Result so far: 47843.45695364
Subtract 1812 from 1920 to get 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

The quotient of the division is 47843.45695364, and the remainder is 1.08e-07.
