87411490 ÷ 421 
We want to divide 87411490 by 421.

Going ahead to step 1:
421 goes into 8 0 times with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Bring next digit (7) of the dividend behind the 8 and repeat the process: 87 / 421

Step 2:
421 goes into 87 0 times with a remainder of 87.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 87 to get 87.
Append the next digit (4) from the dividend to 87 and continue with: 874 / 421

On to step 3:
874 divided by 421 is 2 with a remainder of 32.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtracting 842 from 874 leaves us with 32.
Grab the next digit (1) from the dividend, add it to 32, then carry on: 321 / 421

Step 4:
321 divided by 421 is 0 with a remainder of 321.
The number 0 becomes the next digit in our result. 
Result so far: 20.0
Subtract 0 from 321 to get 321.
Fetch the next digit (1) from the dividend, attach it to 321 and continue: 3211 / 421

Moving on to step 5:
421 goes into 3211 7 times with a remainder of 264.
Put 7 as the next digit of the answer. 
Result so far: 207.0
Deduct 2947 from 3211 and we're left with 264.
Include the next digit (4) from the dividend after 264, then repeat: 2644 / 421

Let's proceed to step 6:
When dividing 2644 by 421, we get 6 with a remainder of 118.
The number 6 becomes the next digit in our result. 
Result so far: 2076.0
Subtract 2526 from 2644 to get 118.
Include the next digit (9) from the dividend after 118, then repeat: 1189 / 421

Advancing to step 7:
If we divide 1189 by 421, we get 2 and a remainder of 347.
Record the quotient 2 as the next digit in the result. 
Result so far: 20762.0
The remainder is 347 after subtracting 842 from 1189.
Append the next digit (0) from the dividend to 347 and continue with: 3470 / 421

Going ahead to step 8:
421 goes into 3470 8 times with a remainder of 102.
Put 8 as the next digit of the answer. 
Result so far: 207628.0
The remainder is 102 after subtracting 3368 from 3470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

Going ahead to step 9:
421 can be fit into 1020 2 times, resulting in a remainder of 178.
Write down 2 as next digit of the result. 
Result so far: 207628.2
Subtracting 842 from 1020 leaves us with 178.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1780, and continue the process.

Advancing to step 10:
The number 421 fits into 1780 4 times, leaving a remainder of 96.
Write down 4 as next digit of the result. 
Result so far: 207628.24
Deduct 1684 from 1780 and we're left with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Going ahead to step 11:
960 divided by 421 is 2 with a remainder of 118.
Put 2 as the next digit of the answer. 
Result so far: 207628.242
If we subtract 842 from 960, we get 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

Moving on to step 12:
If we divide 1180 by 421, we get 2 and a remainder of 338.
Put 2 as the next digit of the answer. 
Result so far: 207628.2422
The remainder is 338 after subtracting 842 from 1180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3380, and continue the process.

The final result is 207628.2422 with a remainder of 0.00338.
