Let's divide 21507608 by 473
Our goal is to divide 21507608 by 473.

Advancing to step 1:
If we divide 2 by 473, we get 0 and a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 473

Going ahead to step 2:
If we divide 21 by 473, we get 0 and a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 21 and we're left with 21.
Grab the next digit (5) from the dividend, add it to 21, then carry on: 215 / 473

Let's proceed to step 3:
473 can be fit into 215 0 times, resulting in a remainder of 215.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 215, we get 215.
Grab the next digit (0) from the dividend, add it to 215, then carry on: 2150 / 473

On to step 4:
If we divide 2150 by 473, we get 4 and a remainder of 258.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we subtract 1892 from 2150, we get 258.
Append the next digit (7) from the dividend to 258 and continue with: 2587 / 473

Let's proceed to step 5:
473 can be fit into 2587 5 times, resulting in a remainder of 222.
Use 5 as the next digit of our solution. 
Result so far: 45.0
The remainder is 222 after subtracting 2365 from 2587.
Append the next digit (6) from the dividend to 222 and continue with: 2226 / 473

On to step 6:
If we divide 2226 by 473, we get 4 and a remainder of 334.
The number 4 becomes the next digit in our result. 
Result so far: 454.0
If we subtract 1892 from 2226, we get 334.
Bring next digit (0) of the dividend behind the 334 and repeat the process: 3340 / 473

Advancing to step 7:
3340 divided by 473 is 7 with a remainder of 29.
Use 7 as the next digit of our solution. 
Result so far: 4547.0
Subtract 3311 from 3340 to get 29.
Append the next digit (8) from the dividend to 29 and continue with: 298 / 473

Advancing to step 8:
When dividing 298 by 473, we get 0 with a remainder of 298.
Record the quotient 0 as the next digit in the result. 
Result so far: 45470.0
If we take 0 away from 298, we end up with 298.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2980, and continue the process.

Advancing to step 9:
2980 divided by 473 is 6 with a remainder of 142.
The next digit of our result is 6. 
Result so far: 45470.6
Deduct 2838 from 2980 and we're left with 142.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

Let's proceed to step 10:
If we divide 1420 by 473, we get 3 and a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 45470.63
Subtract 1419 from 1420 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 11:
The number 473 fits into 10 0 times, leaving a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 45470.63
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 12:
100 divided by 473 is 0 with a remainder of 100.
Write down 0 as next digit of the result. 
Result so far: 45470.63
If we take 0 away from 100, we end up with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

The final result is 45470.63 with a remainder of 0.001.
