We look at the division of 37343 by 86 
Let's see how many times 86 fits into 37343.

Moving on to step 1:
3 divided by 86 is 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Fetch the next digit (7) from the dividend, attach it to 3 and continue: 37 / 86

Moving on to step 2:
If we divide 37 by 86, we get 0 and a remainder of 37.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 37, we get 37.
Take the next digit (3) from the dividend and append it to 37, then repeat: 373 / 86

Let's proceed to step 3:
The number 86 fits into 373 4 times, leaving a remainder of 29.
The next digit of our result is 4. 
Result so far: 4.0
Subtracting 344 from 373 leaves us with 29.
Append the next digit (4) from the dividend to 29 and continue with: 294 / 86

On to step 4:
When dividing 294 by 86, we get 3 with a remainder of 36.
Record the quotient 3 as the next digit in the result. 
Result so far: 43.0
If we take 258 away from 294, we end up with 36.
Include the next digit (3) from the dividend after 36, then repeat: 363 / 86

Advancing to step 5:
86 goes into 363 4 times with a remainder of 19.
Use 4 as the next digit of our solution. 
Result so far: 434.0
Subtract 344 from 363 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 6:
190 divided by 86 is 2 with a remainder of 18.
The number 2 becomes the next digit in our result. 
Result so far: 434.2
If we take 172 away from 190, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 7:
The number 86 fits into 180 2 times, leaving a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 434.22
Deduct 172 from 180 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

After the division, we end up with 434.22 and a remainder of 0.008.
