Let's divide 437398 by 86
Let's see how many times 86 fits into 437398.

Going ahead to step 1:
86 goes into 4 0 times with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Append the next digit (3) from the dividend to 4 and continue with: 43 / 86

Let's proceed to step 2:
43 divided by 86 is 0 with a remainder of 43.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 43, we end up with 43.
Bring next digit (7) of the dividend behind the 43 and repeat the process: 437 / 86

Going ahead to step 3:
86 goes into 437 5 times with a remainder of 7.
Write down 5 as next digit of the result. 
Result so far: 5.0
If we take 430 away from 437, we end up with 7.
Bring next digit (3) of the dividend behind the 7 and repeat the process: 73 / 86

Let's proceed to step 4:
86 goes into 73 0 times with a remainder of 73.
Write down 0 as next digit of the result. 
Result so far: 50.0
Deduct 0 from 73 and we're left with 73.
Fetch the next digit (9) from the dividend, attach it to 73 and continue: 739 / 86

Step 5:
86 can be fit into 739 8 times, resulting in a remainder of 51.
The number 8 becomes the next digit in our result. 
Result so far: 508.0
The remainder is 51 after subtracting 688 from 739.
Include the next digit (8) from the dividend after 51, then repeat: 518 / 86

Advancing to step 6:
518 divided by 86 is 6 with a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 5086.0
Subtract 516 from 518 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 7:
86 can be fit into 20 0 times, resulting in a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 5086.0
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 8:
86 goes into 200 2 times with a remainder of 28.
The number 2 becomes the next digit in our result. 
Result so far: 5086.02
Deduct 172 from 200 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 9:
280 divided by 86 is 3 with a remainder of 22.
Put 3 as the next digit of the answer. 
Result so far: 5086.023
Subtracting 258 from 280 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 10:
If we divide 220 by 86, we get 2 and a remainder of 48.
Put 2 as the next digit of the answer. 
Result so far: 5086.0232
If we take 172 away from 220, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 11:
If we divide 480 by 86, we get 5 and a remainder of 50.
The next digit of our result is 5. 
Result so far: 5086.02325
The remainder is 50 after subtracting 430 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 12:
If we divide 500 by 86, we get 5 and a remainder of 70.
Put 5 as the next digit of the answer. 
Result so far: 5086.023255
Deduct 430 from 500 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

The final outcome is 5086.023255, with a leftover of 7e-06.
