We're dividing 90540751 by 70 
We're looking to find how many times 70 goes into 90540751.

Going ahead to step 1:
When dividing 9 by 70, we get 0 with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Fetch the next digit (0) from the dividend, attach it to 9 and continue: 90 / 70

Advancing to step 2:
90 divided by 70 is 1 with a remainder of 20.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 70 from 90 leaves us with 20.
Grab the next digit (5) from the dividend, add it to 20, then carry on: 205 / 70

Step 3:
205 divided by 70 is 2 with a remainder of 65.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
Subtract 140 from 205 to get 65.
Include the next digit (4) from the dividend after 65, then repeat: 654 / 70

Let's proceed to step 4:
654 divided by 70 is 9 with a remainder of 24.
Use 9 as the next digit of our solution. 
Result so far: 129.0
Subtract 630 from 654 to get 24.
Bring next digit (0) of the dividend behind the 24 and repeat the process: 240 / 70

Advancing to step 5:
70 goes into 240 3 times with a remainder of 30.
Use 3 as the next digit of our solution. 
Result so far: 1293.0
The remainder is 30 after subtracting 210 from 240.
Include the next digit (7) from the dividend after 30, then repeat: 307 / 70

Going ahead to step 6:
The number 70 fits into 307 4 times, leaving a remainder of 27.
Use 4 as the next digit of our solution. 
Result so far: 12934.0
If we subtract 280 from 307, we get 27.
Fetch the next digit (5) from the dividend, attach it to 27 and continue: 275 / 70

Step 7:
275 divided by 70 is 3 with a remainder of 65.
Record the quotient 3 as the next digit in the result. 
Result so far: 129343.0
Subtract 210 from 275 to get 65.
Fetch the next digit (1) from the dividend, attach it to 65 and continue: 651 / 70

Moving on to step 8:
The number 70 fits into 651 9 times, leaving a remainder of 21.
The number 9 becomes the next digit in our result. 
Result so far: 1293439.0
If we subtract 630 from 651, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 9:
70 goes into 210 3 times with a remainder of 0.
Use 3 as the next digit of our solution. 
Result so far: 1293439.3
Subtracting 210 from 210 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 10:
70 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 1293439.3
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 11:
0 divided by 70 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 1293439.3
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 1293439.3 with a remaining 0.0.
