We're dividing 61378 by 90 
We're looking to find how many times 90 goes into 61378.

Moving on to step 1:
90 goes into 6 0 times with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Append the next digit (1) from the dividend to 6 and continue with: 61 / 90

On to step 2:
The number 90 fits into 61 0 times, leaving a remainder of 61.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 61, we end up with 61.
Fetch the next digit (3) from the dividend, attach it to 61 and continue: 613 / 90

Step 3:
613 divided by 90 is 6 with a remainder of 73.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Subtract 540 from 613 to get 73.
Append the next digit (7) from the dividend to 73 and continue with: 737 / 90

Step 4:
90 goes into 737 8 times with a remainder of 17.
Write down 8 as next digit of the result. 
Result so far: 68.0
If we take 720 away from 737, we end up with 17.
Grab the next digit (8) from the dividend, add it to 17, then carry on: 178 / 90

Advancing to step 5:
90 can be fit into 178 1 times, resulting in a remainder of 88.
Record the quotient 1 as the next digit in the result. 
Result so far: 681.0
The remainder is 88 after subtracting 90 from 178.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Advancing to step 6:
880 divided by 90 is 9 with a remainder of 70.
The number 9 becomes the next digit in our result. 
Result so far: 681.9
Subtract 810 from 880 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Step 7:
If we divide 700 by 90, we get 7 and a remainder of 70.
Record the quotient 7 as the next digit in the result. 
Result so far: 681.97
If we take 630 away from 700, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Moving on to step 8:
When dividing 700 by 90, we get 7 with a remainder of 70.
Record the quotient 7 as the next digit in the result. 
Result so far: 681.977
Subtract 630 from 700 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

The final result is 681.977 with a remainder of 0.007.
