21652401 ÷ 434 
We want to divide 21652401 by 434.

Moving on to step 1:
The number 434 fits into 2 0 times, leaving a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 434

On to step 2:
When dividing 21 by 434, we get 0 with a remainder of 21.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 21 leaves us with 21.
Grab the next digit (6) from the dividend, add it to 21, then carry on: 216 / 434

Advancing to step 3:
When dividing 216 by 434, we get 0 with a remainder of 216.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 216, we end up with 216.
Append the next digit (5) from the dividend to 216 and continue with: 2165 / 434

Let's proceed to step 4:
The number 434 fits into 2165 4 times, leaving a remainder of 429.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we take 1736 away from 2165, we end up with 429.
Include the next digit (2) from the dividend after 429, then repeat: 4292 / 434

On to step 5:
434 can be fit into 4292 9 times, resulting in a remainder of 386.
The next digit of our result is 9. 
Result so far: 49.0
Deduct 3906 from 4292 and we're left with 386.
Grab the next digit (4) from the dividend, add it to 386, then carry on: 3864 / 434

Going ahead to step 6:
434 can be fit into 3864 8 times, resulting in a remainder of 392.
Write down 8 as next digit of the result. 
Result so far: 498.0
If we take 3472 away from 3864, we end up with 392.
Append the next digit (0) from the dividend to 392 and continue with: 3920 / 434

On to step 7:
434 goes into 3920 9 times with a remainder of 14.
The next digit of our result is 9. 
Result so far: 4989.0
The remainder is 14 after subtracting 3906 from 3920.
Fetch the next digit (1) from the dividend, attach it to 14 and continue: 141 / 434

Moving on to step 8:
434 can be fit into 141 0 times, resulting in a remainder of 141.
Record the quotient 0 as the next digit in the result. 
Result so far: 49890.0
Subtracting 0 from 141 leaves us with 141.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1410, and continue the process.

Step 9:
When dividing 1410 by 434, we get 3 with a remainder of 108.
Write down 3 as next digit of the result. 
Result so far: 49890.3
Subtract 1302 from 1410 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.

Moving on to step 10:
If we divide 1080 by 434, we get 2 and a remainder of 212.
Write down 2 as next digit of the result. 
Result so far: 49890.32
Subtracting 868 from 1080 leaves us with 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

Moving on to step 11:
The number 434 fits into 2120 4 times, leaving a remainder of 384.
Put 4 as the next digit of the answer. 
Result so far: 49890.324
Subtracting 1736 from 2120 leaves us with 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

On to step 12:
434 can be fit into 3840 8 times, resulting in a remainder of 368.
The number 8 becomes the next digit in our result. 
Result so far: 49890.3248
If we take 3472 away from 3840, we end up with 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

Going ahead to step 13:
434 goes into 3680 8 times with a remainder of 208.
The number 8 becomes the next digit in our result. 
Result so far: 49890.32488
If we subtract 3472 from 3680, we get 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

The final outcome is 49890.32488, with a leftover of 0.000208.
