Let's divide 436887 by 86
We're looking to find how many times 86 goes into 436887.

On to step 1:
86 can be fit into 4 0 times, resulting in a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Fetch the next digit (3) from the dividend, attach it to 4 and continue: 43 / 86

Going ahead to step 2:
The number 86 fits into 43 0 times, leaving a remainder of 43.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 43 to get 43.
Bring next digit (6) of the dividend behind the 43 and repeat the process: 436 / 86

Going ahead to step 3:
86 can be fit into 436 5 times, resulting in a remainder of 6.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
If we take 430 away from 436, we end up with 6.
Fetch the next digit (8) from the dividend, attach it to 6 and continue: 68 / 86

Let's proceed to step 4:
If we divide 68 by 86, we get 0 and a remainder of 68.
The number 0 becomes the next digit in our result. 
Result so far: 50.0
The remainder is 68 after subtracting 0 from 68.
Take the next digit (8) from the dividend and append it to 68, then repeat: 688 / 86

Moving on to step 5:
688 divided by 86 is 8 with a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 508.0
Subtracting 688 from 688 leaves us with 0.
Include the next digit (7) from the dividend after 0, then repeat: 7 / 86

Advancing to step 6:
7 divided by 86 is 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 5080.0
The remainder is 7 after subtracting 0 from 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 7:
86 goes into 70 0 times with a remainder of 70.
The number 0 becomes the next digit in our result. 
Result so far: 5080.0
The remainder is 70 after subtracting 0 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Step 8:
The number 86 fits into 700 8 times, leaving a remainder of 12.
Put 8 as the next digit of the answer. 
Result so far: 5080.08
Subtract 688 from 700 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 9:
120 divided by 86 is 1 with a remainder of 34.
Write down 1 as next digit of the result. 
Result so far: 5080.081
The remainder is 34 after subtracting 86 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 10:
When dividing 340 by 86, we get 3 with a remainder of 82.
Put 3 as the next digit of the answer. 
Result so far: 5080.0813
If we take 258 away from 340, we end up with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Step 11:
The number 86 fits into 820 9 times, leaving a remainder of 46.
The next digit of our result is 9. 
Result so far: 5080.08139
Subtracting 774 from 820 leaves us with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Advancing to step 12:
When dividing 460 by 86, we get 5 with a remainder of 30.
The number 5 becomes the next digit in our result. 
Result so far: 5080.081395
Subtract 430 from 460 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 13:
If we divide 300 by 86, we get 3 and a remainder of 42.
The next digit of our result is 3. 
Result so far: 5080.0813953
If we subtract 258 from 300, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 14:
420 divided by 86 is 4 with a remainder of 76.
Record the quotient 4 as the next digit in the result. 
Result so far: 5080.08139534
Subtract 344 from 420 to get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

The final result is 5080.08139534 with a remainder of 7.6e-08.
