We're dividing 758161 by 90 
We want to divide 758161 by 90.

Let's proceed to step 1:
The number 90 fits into 7 0 times, leaving a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Include the next digit (5) from the dividend after 7, then repeat: 75 / 90

Step 2:
75 divided by 90 is 0 with a remainder of 75.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 75 to get 75.
Include the next digit (8) from the dividend after 75, then repeat: 758 / 90

Going ahead to step 3:
90 goes into 758 8 times with a remainder of 38.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Subtracting 720 from 758 leaves us with 38.
Fetch the next digit (1) from the dividend, attach it to 38 and continue: 381 / 90

On to step 4:
If we divide 381 by 90, we get 4 and a remainder of 21.
Put 4 as the next digit of the answer. 
Result so far: 84.0
If we subtract 360 from 381, we get 21.
Include the next digit (6) from the dividend after 21, then repeat: 216 / 90

Moving on to step 5:
When dividing 216 by 90, we get 2 with a remainder of 36.
Use 2 as the next digit of our solution. 
Result so far: 842.0
Subtract 180 from 216 to get 36.
Take the next digit (1) from the dividend and append it to 36, then repeat: 361 / 90

Advancing to step 6:
The number 90 fits into 361 4 times, leaving a remainder of 1.
Use 4 as the next digit of our solution. 
Result so far: 8424.0
If we take 360 away from 361, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 7:
90 goes into 10 0 times with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 8424.0
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 8:
100 divided by 90 is 1 with a remainder of 10.
Put 1 as the next digit of the answer. 
Result so far: 8424.01
The remainder is 10 after subtracting 90 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 9:
90 goes into 100 1 times with a remainder of 10.
Use 1 as the next digit of our solution. 
Result so far: 8424.011
The remainder is 10 after subtracting 90 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final result is 8424.011 with a remainder of 0.001.
