Let's divide 21555157 by 447
We want to divide 21555157 by 447.

Advancing to step 1:
The number 447 fits into 2 0 times, leaving a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 447

Going ahead to step 2:
The number 447 fits into 21 0 times, leaving a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 21, we get 21.
Include the next digit (5) from the dividend after 21, then repeat: 215 / 447

Let's proceed to step 3:
215 divided by 447 is 0 with a remainder of 215.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 215, we end up with 215.
Append the next digit (5) from the dividend to 215 and continue with: 2155 / 447

Advancing to step 4:
When dividing 2155 by 447, we get 4 with a remainder of 367.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
The remainder is 367 after subtracting 1788 from 2155.
Grab the next digit (5) from the dividend, add it to 367, then carry on: 3675 / 447

Let's proceed to step 5:
If we divide 3675 by 447, we get 8 and a remainder of 99.
The next digit of our result is 8. 
Result so far: 48.0
Subtracting 3576 from 3675 leaves us with 99.
Fetch the next digit (1) from the dividend, attach it to 99 and continue: 991 / 447

Advancing to step 6:
447 can be fit into 991 2 times, resulting in a remainder of 97.
The next digit of our result is 2. 
Result so far: 482.0
Deduct 894 from 991 and we're left with 97.
Bring next digit (5) of the dividend behind the 97 and repeat the process: 975 / 447

Let's proceed to step 7:
447 goes into 975 2 times with a remainder of 81.
Use 2 as the next digit of our solution. 
Result so far: 4822.0
The remainder is 81 after subtracting 894 from 975.
Append the next digit (7) from the dividend to 81 and continue with: 817 / 447

Moving on to step 8:
447 goes into 817 1 times with a remainder of 370.
Write down 1 as next digit of the result. 
Result so far: 48221.0
Subtracting 447 from 817 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.

Moving on to step 9:
The number 447 fits into 3700 8 times, leaving a remainder of 124.
Put 8 as the next digit of the answer. 
Result so far: 48221.8
If we take 3576 away from 3700, we end up with 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

Step 10:
447 goes into 1240 2 times with a remainder of 346.
Record the quotient 2 as the next digit in the result. 
Result so far: 48221.82
If we take 894 away from 1240, we end up with 346.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3460, and continue the process.

Moving on to step 11:
447 can be fit into 3460 7 times, resulting in a remainder of 331.
Write down 7 as next digit of the result. 
Result so far: 48221.827
If we take 3129 away from 3460, we end up with 331.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3310, and continue the process.

Advancing to step 12:
447 goes into 3310 7 times with a remainder of 181.
Put 7 as the next digit of the answer. 
Result so far: 48221.8277
If we subtract 3129 from 3310, we get 181.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1810, and continue the process.

The quotient of the division is 48221.8277, and the remainder is 0.00181.
