We divide 351692 by 90
We want to divide 351692 by 90.

Step 1:
When dividing 3 by 90, we get 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Grab the next digit (5) from the dividend, add it to 3, then carry on: 35 / 90

On to step 2:
35 divided by 90 is 0 with a remainder of 35.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 35 to get 35.
Fetch the next digit (1) from the dividend, attach it to 35 and continue: 351 / 90

On to step 3:
90 can be fit into 351 3 times, resulting in a remainder of 81.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we take 270 away from 351, we end up with 81.
Append the next digit (6) from the dividend to 81 and continue with: 816 / 90

Going ahead to step 4:
90 can be fit into 816 9 times, resulting in a remainder of 6.
Write down 9 as next digit of the result. 
Result so far: 39.0
If we take 810 away from 816, we end up with 6.
Fetch the next digit (9) from the dividend, attach it to 6 and continue: 69 / 90

On to step 5:
When dividing 69 by 90, we get 0 with a remainder of 69.
The number 0 becomes the next digit in our result. 
Result so far: 390.0
Subtracting 0 from 69 leaves us with 69.
Grab the next digit (2) from the dividend, add it to 69, then carry on: 692 / 90

Going ahead to step 6:
90 goes into 692 7 times with a remainder of 62.
The number 7 becomes the next digit in our result. 
Result so far: 3907.0
If we take 630 away from 692, we end up with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Advancing to step 7:
90 goes into 620 6 times with a remainder of 80.
Use 6 as the next digit of our solution. 
Result so far: 3907.6
If we take 540 away from 620, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 8:
800 divided by 90 is 8 with a remainder of 80.
Use 8 as the next digit of our solution. 
Result so far: 3907.68
Subtracting 720 from 800 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 9:
If we divide 800 by 90, we get 8 and a remainder of 80.
Write down 8 as next digit of the result. 
Result so far: 3907.688
Deduct 720 from 800 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

After the division, we end up with 3907.688 and a remainder of 0.008.
