We divide 21006140 by 434
Let's see how many times 434 fits into 21006140.

Going ahead to step 1:
434 can be fit into 2 0 times, resulting in a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 434

Let's proceed to step 2:
If we divide 21 by 434, we get 0 and a remainder of 21.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 21 and we're left with 21.
Fetch the next digit (0) from the dividend, attach it to 21 and continue: 210 / 434

Step 3:
434 goes into 210 0 times with a remainder of 210.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 210, we end up with 210.
Grab the next digit (0) from the dividend, add it to 210, then carry on: 2100 / 434

Going ahead to step 4:
434 can be fit into 2100 4 times, resulting in a remainder of 364.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we take 1736 away from 2100, we end up with 364.
Append the next digit (6) from the dividend to 364 and continue with: 3646 / 434

Let's proceed to step 5:
3646 divided by 434 is 8 with a remainder of 174.
Write down 8 as next digit of the result. 
Result so far: 48.0
If we take 3472 away from 3646, we end up with 174.
Fetch the next digit (1) from the dividend, attach it to 174 and continue: 1741 / 434

Step 6:
When dividing 1741 by 434, we get 4 with a remainder of 5.
The number 4 becomes the next digit in our result. 
Result so far: 484.0
If we subtract 1736 from 1741, we get 5.
Append the next digit (4) from the dividend to 5 and continue with: 54 / 434

Moving on to step 7:
434 goes into 54 0 times with a remainder of 54.
Use 0 as the next digit of our solution. 
Result so far: 4840.0
If we take 0 away from 54, we end up with 54.
Take the next digit (0) from the dividend and append it to 54, then repeat: 540 / 434

Step 8:
540 divided by 434 is 1 with a remainder of 106.
Use 1 as the next digit of our solution. 
Result so far: 48401.0
Deduct 434 from 540 and we're left with 106.
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:
The number 434 fits into 1060 2 times, leaving a remainder of 192.
The number 2 becomes the next digit in our result. 
Result so far: 48401.2
If we subtract 868 from 1060, we get 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 10:
If we divide 1920 by 434, we get 4 and a remainder of 184.
Write down 4 as next digit of the result. 
Result so far: 48401.24
Deduct 1736 from 1920 and we're left with 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Step 11:
1840 divided by 434 is 4 with a remainder of 104.
The number 4 becomes the next digit in our result. 
Result so far: 48401.244
Deduct 1736 from 1840 and we're left with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

The final outcome is 48401.244, with a leftover of 0.0104.
