Let's divide 17520969 by 421
Let's see how many times 421 fits into 17520969.

Going ahead to step 1:
The number 421 fits into 1 0 times, leaving a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Fetch the next digit (7) from the dividend, attach it to 1 and continue: 17 / 421

On to step 2:
If we divide 17 by 421, we get 0 and a remainder of 17.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 17 leaves us with 17.
Bring next digit (5) of the dividend behind the 17 and repeat the process: 175 / 421

Going ahead to step 3:
If we divide 175 by 421, we get 0 and a remainder of 175.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 175, we end up with 175.
Include the next digit (2) from the dividend after 175, then repeat: 1752 / 421

Step 4:
421 goes into 1752 4 times with a remainder of 68.
Write down 4 as next digit of the result. 
Result so far: 4.0
The remainder is 68 after subtracting 1684 from 1752.
Fetch the next digit (0) from the dividend, attach it to 68 and continue: 680 / 421

On to step 5:
When dividing 680 by 421, we get 1 with a remainder of 259.
Write down 1 as next digit of the result. 
Result so far: 41.0
Subtracting 421 from 680 leaves us with 259.
Grab the next digit (9) from the dividend, add it to 259, then carry on: 2599 / 421

Moving on to step 6:
When dividing 2599 by 421, we get 6 with a remainder of 73.
The next digit of our result is 6. 
Result so far: 416.0
Subtract 2526 from 2599 to get 73.
Bring next digit (6) of the dividend behind the 73 and repeat the process: 736 / 421

Step 7:
421 can be fit into 736 1 times, resulting in a remainder of 315.
Record the quotient 1 as the next digit in the result. 
Result so far: 4161.0
Subtracting 421 from 736 leaves us with 315.
Fetch the next digit (9) from the dividend, attach it to 315 and continue: 3159 / 421

Moving on to step 8:
When dividing 3159 by 421, we get 7 with a remainder of 212.
The number 7 becomes the next digit in our result. 
Result so far: 41617.0
If we take 2947 away from 3159, we end up 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.

Advancing to step 9:
The number 421 fits into 2120 5 times, leaving a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 41617.5
Subtract 2105 from 2120 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 10:
150 divided by 421 is 0 with a remainder of 150.
The next digit of our result is 0. 
Result so far: 41617.5
Deduct 0 from 150 and we're left with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Moving on to step 11:
1500 divided by 421 is 3 with a remainder of 237.
Record the quotient 3 as the next digit in the result. 
Result so far: 41617.503
Deduct 1263 from 1500 and we're left with 237.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2370, and continue the process.

Moving on to step 12:
421 can be fit into 2370 5 times, resulting in a remainder of 265.
The next digit of our result is 5. 
Result so far: 41617.5035
If we subtract 2105 from 2370, we get 265.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2650, and continue the process.

Moving on to step 13:
2650 divided by 421 is 6 with a remainder of 124.
The next digit of our result is 6. 
Result so far: 41617.50356
The remainder is 124 after subtracting 2526 from 2650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

Step 14:
421 can be fit into 1240 2 times, resulting in a remainder of 398.
Record the quotient 2 as the next digit in the result. 
Result so far: 41617.503562
If we subtract 842 from 1240, we get 398.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3980, and continue the process.

Going ahead to step 15:
The number 421 fits into 3980 9 times, leaving a remainder of 191.
Write down 9 as next digit of the result. 
Result so far: 41617.5035629
Deduct 3789 from 3980 and we're left with 191.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1910, and continue the process.

On to step 16:
When dividing 1910 by 421, we get 4 with a remainder of 226.
The next digit of our result is 4. 
Result so far: 41617.50356294
If we take 1684 away from 1910, we end up with 226.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

Our division results in 41617.50356294 with a remaining 2.26e-07.
