670614 ÷ 90 
We're looking to find how many times 90 goes into 670614.

Let's proceed to step 1:
6 divided by 90 is 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Include the next digit (7) from the dividend after 6, then repeat: 67 / 90

On to step 2:
67 divided by 90 is 0 with a remainder of 67.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 67, we end up with 67.
Bring next digit (0) of the dividend behind the 67 and repeat the process: 670 / 90

Going ahead to step 3:
90 can be fit into 670 7 times, resulting in a remainder of 40.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Subtracting 630 from 670 leaves us with 40.
Include the next digit (6) from the dividend after 40, then repeat: 406 / 90

Step 4:
When dividing 406 by 90, we get 4 with a remainder of 46.
Use 4 as the next digit of our solution. 
Result so far: 74.0
The remainder is 46 after subtracting 360 from 406.
Include the next digit (1) from the dividend after 46, then repeat: 461 / 90

Moving on to step 5:
When dividing 461 by 90, we get 5 with a remainder of 11.
Use 5 as the next digit of our solution. 
Result so far: 745.0
If we subtract 450 from 461, we get 11.
Grab the next digit (4) from the dividend, add it to 11, then carry on: 114 / 90

Let's proceed to step 6:
90 goes into 114 1 times with a remainder of 24.
Use 1 as the next digit of our solution. 
Result so far: 7451.0
If we take 90 away from 114, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 7:
The number 90 fits into 240 2 times, leaving a remainder of 60.
Use 2 as the next digit of our solution. 
Result so far: 7451.2
If we take 180 away from 240, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 8:
90 can be fit into 600 6 times, resulting in a remainder of 60.
Record the quotient 6 as the next digit in the result. 
Result so far: 7451.26
If we subtract 540 from 600, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 9:
600 divided by 90 is 6 with a remainder of 60.
The next digit of our result is 6. 
Result so far: 7451.266
Subtracting 540 from 600 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

The final outcome is 7451.266, with a leftover of 0.006.
