Let's divide 21626535 by 421
We want to divide 21626535 by 421.

Let's proceed to step 1:
The number 421 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 / 421

Moving on to step 2:
When dividing 21 by 421, we get 0 with a remainder of 21.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 21 leaves us with 21.
Fetch the next digit (6) from the dividend, attach it to 21 and continue: 216 / 421

Advancing to step 3:
If we divide 216 by 421, we get 0 and a remainder of 216.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 216, we get 216.
Fetch the next digit (2) from the dividend, attach it to 216 and continue: 2162 / 421

Let's proceed to step 4:
2162 divided by 421 is 5 with a remainder of 57.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Deduct 2105 from 2162 and we're left with 57.
Append the next digit (6) from the dividend to 57 and continue with: 576 / 421

On to step 5:
The number 421 fits into 576 1 times, leaving a remainder of 155.
Put 1 as the next digit of the answer. 
Result so far: 51.0
If we take 421 away from 576, we end up with 155.
Fetch the next digit (5) from the dividend, attach it to 155 and continue: 1555 / 421

Going ahead to step 6:
1555 divided by 421 is 3 with a remainder of 292.
Record the quotient 3 as the next digit in the result. 
Result so far: 513.0
If we take 1263 away from 1555, we end up with 292.
Fetch the next digit (3) from the dividend, attach it to 292 and continue: 2923 / 421

Step 7:
421 goes into 2923 6 times with a remainder of 397.
Use 6 as the next digit of our solution. 
Result so far: 5136.0
Subtracting 2526 from 2923 leaves us with 397.
Append the next digit (5) from the dividend to 397 and continue with: 3975 / 421

Step 8:
421 goes into 3975 9 times with a remainder of 186.
Record the quotient 9 as the next digit in the result. 
Result so far: 51369.0
Deduct 3789 from 3975 and we're left with 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

On to step 9:
1860 divided by 421 is 4 with a remainder of 176.
Put 4 as the next digit of the answer. 
Result so far: 51369.4
Deduct 1684 from 1860 and we're left with 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Let's proceed to step 10:
421 can be fit into 1760 4 times, resulting in a remainder of 76.
The number 4 becomes the next digit in our result. 
Result so far: 51369.44
Subtract 1684 from 1760 to get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Our division results in 51369.44 with a remaining 0.076.
