Let's divide 365431 by 87
Let's see how many times 87 fits into 365431.

Moving on to step 1:
3 divided by 87 is 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Include the next digit (6) from the dividend after 3, then repeat: 36 / 87

Moving on to step 2:
36 divided by 87 is 0 with a remainder of 36.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 36, we get 36.
Include the next digit (5) from the dividend after 36, then repeat: 365 / 87

Going ahead to step 3:
87 can be fit into 365 4 times, resulting in a remainder of 17.
Use 4 as the next digit of our solution. 
Result so far: 4.0
The remainder is 17 after subtracting 348 from 365.
Take the next digit (4) from the dividend and append it to 17, then repeat: 174 / 87

Advancing to step 4:
87 can be fit into 174 2 times, resulting in a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 42.0
Deduct 174 from 174 and we're left with 0.
Take the next digit (3) from the dividend and append it to 0, then repeat: 3 / 87

Moving on to step 5:
87 goes into 3 0 times with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 420.0
Subtracting 0 from 3 leaves us with 3.
Fetch the next digit (1) from the dividend, attach it to 3 and continue: 31 / 87

Moving on to step 6:
31 divided by 87 is 0 with a remainder of 31.
The next digit of our result is 0. 
Result so far: 4200.0
Deduct 0 from 31 and we're left with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

On to step 7:
87 goes into 310 3 times with a remainder of 49.
Write down 3 as next digit of the result. 
Result so far: 4200.3
The remainder is 49 after subtracting 261 from 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Let's proceed to step 8:
The number 87 fits into 490 5 times, leaving a remainder of 55.
The next digit of our result is 5. 
Result so far: 4200.35
The remainder is 55 after subtracting 435 from 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Going ahead to step 9:
When dividing 550 by 87, we get 6 with a remainder of 28.
Record the quotient 6 as the next digit in the result. 
Result so far: 4200.356
Subtract 522 from 550 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 10:
The number 87 fits into 280 3 times, leaving a remainder of 19.
Write down 3 as next digit of the result. 
Result so far: 4200.3563
If we take 261 away from 280, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 11:
When dividing 190 by 87, we get 2 with a remainder of 16.
The next digit of our result is 2. 
Result so far: 4200.35632
Subtracting 174 from 190 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 12:
87 can be fit into 160 1 times, resulting in a remainder of 73.
Write down 1 as next digit of the result. 
Result so far: 4200.356321
Subtracting 87 from 160 leaves us with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Let's proceed to step 13:
The number 87 fits into 730 8 times, leaving a remainder of 34.
The next digit of our result is 8. 
Result so far: 4200.3563218
If we subtract 696 from 730, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 14:
The number 87 fits into 340 3 times, leaving a remainder of 79.
Write down 3 as next digit of the result. 
Result so far: 4200.35632183
If we take 261 away from 340, we end up with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Our division results in 4200.35632183 with a remaining 7.9e-08.
