We divide 423581 by 87
We're looking to find how many times 87 goes into 423581.

Moving on to step 1:
If we divide 4 by 87, we get 0 and a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 87

Step 2:
42 divided by 87 is 0 with a remainder of 42.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 42 and we're left with 42.
Bring next digit (3) of the dividend behind the 42 and repeat the process: 423 / 87

Advancing to step 3:
87 can be fit into 423 4 times, resulting in a remainder of 75.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
The remainder is 75 after subtracting 348 from 423.
Take the next digit (5) from the dividend and append it to 75, then repeat: 755 / 87

Going ahead to step 4:
When dividing 755 by 87, we get 8 with a remainder of 59.
The next digit of our result is 8. 
Result so far: 48.0
If we take 696 away from 755, we end up with 59.
Take the next digit (8) from the dividend and append it to 59, then repeat: 598 / 87

Step 5:
The number 87 fits into 598 6 times, leaving a remainder of 76.
Write down 6 as next digit of the result. 
Result so far: 486.0
Deduct 522 from 598 and we're left with 76.
Include the next digit (1) from the dividend after 76, then repeat: 761 / 87

Step 6:
761 divided by 87 is 8 with a remainder of 65.
Record the quotient 8 as the next digit in the result. 
Result so far: 4868.0
If we take 696 away from 761, we end up with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Step 7:
If we divide 650 by 87, we get 7 and a remainder of 41.
Use 7 as the next digit of our solution. 
Result so far: 4868.7
Subtract 609 from 650 to get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Going ahead to step 8:
410 divided by 87 is 4 with a remainder of 62.
Put 4 as the next digit of the answer. 
Result so far: 4868.74
Deduct 348 from 410 and we're left with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Step 9:
If we divide 620 by 87, we get 7 and a remainder of 11.
Record the quotient 7 as the next digit in the result. 
Result so far: 4868.747
The remainder is 11 after subtracting 609 from 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 10:
If we divide 110 by 87, we get 1 and a remainder of 23.
Record the quotient 1 as the next digit in the result. 
Result so far: 4868.7471
If we take 87 away from 110, we end up with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Going ahead to step 11:
87 goes into 230 2 times with a remainder of 56.
Record the quotient 2 as the next digit in the result. 
Result so far: 4868.74712
Deduct 174 from 230 and we're left with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Let's proceed to step 12:
87 goes into 560 6 times with a remainder of 38.
Put 6 as the next digit of the answer. 
Result so far: 4868.747126
Subtracting 522 from 560 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 13:
The number 87 fits into 380 4 times, leaving a remainder of 32.
Write down 4 as next digit of the result. 
Result so far: 4868.7471264
The remainder is 32 after subtracting 348 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 14:
The number 87 fits into 320 3 times, leaving a remainder of 59.
Use 3 as the next digit of our solution. 
Result so far: 4868.74712643
Subtract 261 from 320 to get 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

The final result is 4868.74712643 with a remainder of 5.9e-08.
