We divide 28175070 by 421
Our goal is to divide 28175070 by 421.

Moving on to step 1:
421 goes into 2 0 times with 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.
Grab the next digit (8) from the dividend, add it to 2, then carry on: 28 / 421

On to step 2:
If we divide 28 by 421, we get 0 and a remainder of 28.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 28 leaves us with 28.
Include the next digit (1) from the dividend after 28, then repeat: 281 / 421

Going ahead to step 3:
421 goes into 281 0 times with a remainder of 281.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 281 and we're left with 281.
Append the next digit (7) from the dividend to 281 and continue with: 2817 / 421

Advancing to step 4:
When dividing 2817 by 421, we get 6 with a remainder of 291.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Deduct 2526 from 2817 and we're left with 291.
Append the next digit (5) from the dividend to 291 and continue with: 2915 / 421

Advancing to step 5:
If we divide 2915 by 421, we get 6 and a remainder of 389.
Use 6 as the next digit of our solution. 
Result so far: 66.0
Subtract 2526 from 2915 to get 389.
Grab the next digit (0) from the dividend, add it to 389, then carry on: 3890 / 421

Going ahead to step 6:
3890 divided by 421 is 9 with a remainder of 101.
The next digit of our result is 9. 
Result so far: 669.0
The remainder is 101 after subtracting 3789 from 3890.
Append the next digit (7) from the dividend to 101 and continue with: 1017 / 421

Going ahead to step 7:
421 goes into 1017 2 times with a remainder of 175.
The next digit of our result is 2. 
Result so far: 6692.0
Deduct 842 from 1017 and we're left with 175.
Include the next digit (0) from the dividend after 175, then repeat: 1750 / 421

Advancing to step 8:
1750 divided by 421 is 4 with a remainder of 66.
Put 4 as the next digit of the answer. 
Result so far: 66924.0
The remainder is 66 after subtracting 1684 from 1750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Step 9:
If we divide 660 by 421, we get 1 and a remainder of 239.
Use 1 as the next digit of our solution. 
Result so far: 66924.1
If we subtract 421 from 660, we get 239.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2390, and continue the process.

Going ahead to step 10:
If we divide 2390 by 421, we get 5 and a remainder of 285.
Put 5 as the next digit of the answer. 
Result so far: 66924.15
Subtracting 2105 from 2390 leaves us with 285.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2850, and continue the process.

On to step 11:
2850 divided by 421 is 6 with a remainder of 324.
Write down 6 as next digit of the result. 
Result so far: 66924.156
Subtracting 2526 from 2850 leaves us with 324.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3240, and continue the process.

Let's proceed to step 12:
421 goes into 3240 7 times with a remainder of 293.
Write down 7 as next digit of the result. 
Result so far: 66924.1567
If we subtract 2947 from 3240, we get 293.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2930, and continue the process.

Moving on to step 13:
421 can be fit into 2930 6 times, resulting in a remainder of 404.
The next digit of our result is 6. 
Result so far: 66924.15676
Subtracting 2526 from 2930 leaves us with 404.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4040, and continue the process.

Going ahead to step 14:
The number 421 fits into 4040 9 times, leaving a remainder of 251.
Record the quotient 9 as the next digit in the result. 
Result so far: 66924.156769
Subtracting 3789 from 4040 leaves us with 251.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2510, and continue the process.

On to step 15:
421 goes into 2510 5 times with a remainder of 405.
Record the quotient 5 as the next digit in the result. 
Result so far: 66924.1567695
Subtract 2105 from 2510 to get 405.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4050, and continue the process.

Moving on to step 16:
421 goes into 4050 9 times with a remainder of 261.
Write down 9 as next digit of the result. 
Result so far: 66924.15676959
Subtract 3789 from 4050 to get 261.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2610, and continue the process.

The final result is 66924.15676959 with a remainder of 2.61e-07.
