87541424 divided by 421 
We're looking to find how many times 421 goes into 87541424.

On to step 1:
8 divided by 421 is 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Take the next digit (7) from the dividend and append it to 8, then repeat: 87 / 421

Let's proceed to step 2:
When dividing 87 by 421, we get 0 with a remainder of 87.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 87, we end up with 87.
Take the next digit (5) from the dividend and append it to 87, then repeat: 875 / 421

Let's proceed to step 3:
The number 421 fits into 875 2 times, leaving a remainder of 33.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
The remainder is 33 after subtracting 842 from 875.
Grab the next digit (4) from the dividend, add it to 33, then carry on: 334 / 421

On to step 4:
When dividing 334 by 421, we get 0 with a remainder of 334.
Put 0 as the next digit of the answer. 
Result so far: 20.0
If we subtract 0 from 334, we get 334.
Take the next digit (1) from the dividend and append it to 334, then repeat: 3341 / 421

Moving on to step 5:
If we divide 3341 by 421, we get 7 and a remainder of 394.
Use 7 as the next digit of our solution. 
Result so far: 207.0
Subtract 2947 from 3341 to get 394.
Take the next digit (4) from the dividend and append it to 394, then repeat: 3944 / 421

On to step 6:
When dividing 3944 by 421, we get 9 with a remainder of 155.
Record the quotient 9 as the next digit in the result. 
Result so far: 2079.0
If we subtract 3789 from 3944, we get 155.
Append the next digit (2) from the dividend to 155 and continue with: 1552 / 421

On to step 7:
When dividing 1552 by 421, we get 3 with a remainder of 289.
The number 3 becomes the next digit in our result. 
Result so far: 20793.0
Subtracting 1263 from 1552 leaves us with 289.
Fetch the next digit (4) from the dividend, attach it to 289 and continue: 2894 / 421

Let's proceed to step 8:
If we divide 2894 by 421, we get 6 and a remainder of 368.
The number 6 becomes the next digit in our result. 
Result so far: 207936.0
If we subtract 2526 from 2894, we get 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

Moving on to step 9:
If we divide 3680 by 421, we get 8 and a remainder of 312.
Record the quotient 8 as the next digit in the result. 
Result so far: 207936.8
The remainder is 312 after subtracting 3368 from 3680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

Step 10:
3120 divided by 421 is 7 with a remainder of 173.
Use 7 as the next digit of our solution. 
Result so far: 207936.87
Subtracting 2947 from 3120 leaves us with 173.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1730, and continue the process.

Let's proceed to step 11:
421 goes into 1730 4 times with a remainder of 46.
Put 4 as the next digit of the answer. 
Result so far: 207936.874
The remainder is 46 after subtracting 1684 from 1730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Moving on to step 12:
421 can be fit into 460 1 times, resulting in a remainder of 39.
The next digit of our result is 1. 
Result so far: 207936.8741
Deduct 421 from 460 and we're left with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

On to step 13:
421 goes into 390 0 times with a remainder of 390.
The next digit of our result is 0. 
Result so far: 207936.8741
Deduct 0 from 390 and we're left with 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

Going ahead to step 14:
421 can be fit into 3900 9 times, resulting in a remainder of 111.
Use 9 as the next digit of our solution. 
Result so far: 207936.874109
Deduct 3789 from 3900 and we're left with 111.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1110, and continue the process.

On to step 15:
If we divide 1110 by 421, we get 2 and a remainder of 268.
The next digit of our result is 2. 
Result so far: 207936.8741092
If we take 842 away from 1110, we end up with 268.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

Advancing to step 16:
2680 divided by 421 is 6 with a remainder of 154.
Write down 6 as next digit of the result. 
Result so far: 207936.87410926
Subtracting 2526 from 2680 leaves us with 154.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

The final outcome is 207936.87410926, with a leftover of 1.54e-07.
