We look at the division of 751512 by 90 
We're looking to find how many times 90 goes into 751512.

Let's proceed to step 1:
90 goes into 7 0 times with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Append the next digit (5) from the dividend to 7 and continue with: 75 / 90

Going ahead to step 2:
90 can be fit into 75 0 times, resulting in a remainder of 75.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 75 and we're left with 75.
Grab the next digit (1) from the dividend, add it to 75, then carry on: 751 / 90

Step 3:
When dividing 751 by 90, we get 8 with a remainder of 31.
The next digit of our result is 8. 
Result so far: 8.0
Deduct 720 from 751 and we're left with 31.
Fetch the next digit (5) from the dividend, attach it to 31 and continue: 315 / 90

Let's proceed to step 4:
90 goes into 315 3 times with a remainder of 45.
Use 3 as the next digit of our solution. 
Result so far: 83.0
Subtracting 270 from 315 leaves us with 45.
Grab the next digit (1) from the dividend, add it to 45, then carry on: 451 / 90

On to step 5:
90 goes into 451 5 times with a remainder of 1.
Use 5 as the next digit of our solution. 
Result so far: 835.0
If we take 450 away from 451, we end up with 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 90

On to step 6:
12 divided by 90 is 0 with a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 8350.0
The remainder is 12 after subtracting 0 from 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 7:
120 divided by 90 is 1 with a remainder of 30.
Put 1 as the next digit of the answer. 
Result so far: 8350.1
Deduct 90 from 120 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.

Moving on to step 8:
90 can be fit into 300 3 times, resulting in a remainder of 30.
Put 3 as the next digit of the answer. 
Result so far: 8350.13
Subtracting 270 from 300 leaves us 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.

Let's proceed to step 9:
300 divided by 90 is 3 with a remainder of 30.
Use 3 as the next digit of our solution. 
Result so far: 8350.133
The remainder is 30 after subtracting 270 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

After the division, we end up with 8350.133 and a remainder of 0.003.
