616359 ÷ 90 
We're looking to find how many times 90 goes into 616359.

On to step 1:
90 goes into 6 0 times with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Fetch the next digit (1) from the dividend, attach it to 6 and continue: 61 / 90

Advancing to step 2:
The number 90 fits into 61 0 times, leaving a remainder of 61.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 61, we get 61.
Fetch the next digit (6) from the dividend, attach it to 61 and continue: 616 / 90

Going ahead to step 3:
When dividing 616 by 90, we get 6 with a remainder of 76.
Write down 6 as next digit of the result. 
Result so far: 6.0
Subtract 540 from 616 to get 76.
Append the next digit (3) from the dividend to 76 and continue with: 763 / 90

Step 4:
763 divided by 90 is 8 with a remainder of 43.
Write down 8 as next digit of the result. 
Result so far: 68.0
The remainder is 43 after subtracting 720 from 763.
Append the next digit (5) from the dividend to 43 and continue with: 435 / 90

Advancing to step 5:
435 divided by 90 is 4 with a remainder of 75.
Put 4 as the next digit of the answer. 
Result so far: 684.0
Subtracting 360 from 435 leaves us with 75.
Bring next digit (9) of the dividend behind the 75 and repeat the process: 759 / 90

Advancing to step 6:
The number 90 fits into 759 8 times, leaving a remainder of 39.
Put 8 as the next digit of the answer. 
Result so far: 6848.0
If we take 720 away from 759, we end up with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Moving on to step 7:
390 divided by 90 is 4 with a remainder of 30.
The number 4 becomes the next digit in our result. 
Result so far: 6848.4
The remainder is 30 after subtracting 360 from 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 8:
90 goes into 300 3 times with a remainder of 30.
Use 3 as the next digit of our solution. 
Result so far: 6848.43
Deduct 270 from 300 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 9:
When dividing 300 by 90, we get 3 with a remainder of 30.
The next digit of our result is 3. 
Result so far: 6848.433
Deduct 270 from 300 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Our division results in 6848.433 with a remaining 0.003.
