We look at the division of 346637 by 90 
We're looking to find how many times 90 goes into 346637.

Advancing to step 1:
90 goes into 3 0 times with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Take the next digit (4) from the dividend and append it to 3, then repeat: 34 / 90

Going ahead to step 2:
When dividing 34 by 90, we get 0 with a remainder of 34.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 34 after subtracting 0 from 34.
Append the next digit (6) from the dividend to 34 and continue with: 346 / 90

Step 3:
The number 90 fits into 346 3 times, leaving a remainder of 76.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtract 270 from 346 to get 76.
Take the next digit (6) from the dividend and append it to 76, then repeat: 766 / 90

Going ahead to step 4:
90 goes into 766 8 times with a remainder of 46.
Write down 8 as next digit of the result. 
Result so far: 38.0
Deduct 720 from 766 and we're left with 46.
Include the next digit (3) from the dividend after 46, then repeat: 463 / 90

On to step 5:
90 can be fit into 463 5 times, resulting in a remainder of 13.
The next digit of our result is 5. 
Result so far: 385.0
If we take 450 away from 463, we end up with 13.
Bring next digit (7) of the dividend behind the 13 and repeat the process: 137 / 90

Moving on to step 6:
When dividing 137 by 90, we get 1 with a remainder of 47.
Write down 1 as next digit of the result. 
Result so far: 3851.0
The remainder is 47 after subtracting 90 from 137.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Advancing to step 7:
The number 90 fits into 470 5 times, leaving a remainder of 20.
Put 5 as the next digit of the answer. 
Result so far: 3851.5
If we take 450 away from 470, we end up 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.

On to step 8:
90 goes into 200 2 times with a remainder of 20.
Put 2 as the next digit of the answer. 
Result so far: 3851.52
If we take 180 away from 200, we end up 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.

Moving on to step 9:
200 divided by 90 is 2 with a remainder of 20.
The next digit of our result is 2. 
Result so far: 3851.522
If we take 180 away from 200, we end up 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.

Our division results in 3851.522 with a remaining 0.002.
