We're dividing 75306700 by 970 
We want to figure out the number of times 75306700 can be divided by 970.

Going ahead to step 1:
970 goes into 7 0 times with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Append the next digit (5) from the dividend to 7 and continue with: 75 / 970

Step 2:
970 can be fit into 75 0 times, resulting in a remainder of 75.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 75, we get 75.
Grab the next digit (3) from the dividend, add it to 75, then carry on: 753 / 970

Step 3:
When dividing 753 by 970, we get 0 with a remainder of 753.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 753, we end up with 753.
Grab the next digit (0) from the dividend, add it to 753, then carry on: 7530 / 970

Going ahead to step 4:
The number 970 fits into 7530 7 times, leaving a remainder of 740.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Subtracting 6790 from 7530 leaves us with 740.
Fetch the next digit (6) from the dividend, attach it to 740 and continue: 7406 / 970

Step 5:
7406 divided by 970 is 7 with a remainder of 616.
Record the quotient 7 as the next digit in the result. 
Result so far: 77.0
Deduct 6790 from 7406 and we're left with 616.
Take the next digit (7) from the dividend and append it to 616, then repeat: 6167 / 970

On to step 6:
If we divide 6167 by 970, we get 6 and a remainder of 347.
Use 6 as the next digit of our solution. 
Result so far: 776.0
If we take 5820 away from 6167, we end up with 347.
Grab the next digit (0) from the dividend, add it to 347, then carry on: 3470 / 970

Let's proceed to step 7:
The number 970 fits into 3470 3 times, leaving a remainder of 560.
The number 3 becomes the next digit in our result. 
Result so far: 7763.0
If we subtract 2910 from 3470, we get 560.
Append the next digit (0) from the dividend to 560 and continue with: 5600 / 970

Going ahead to step 8:
970 can be fit into 5600 5 times, resulting in a remainder of 750.
Write down 5 as next digit of the result. 
Result so far: 77635.0
Deduct 4850 from 5600 and we're left with 750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7500, and continue the process.

Going ahead to step 9:
970 can be fit into 7500 7 times, resulting in a remainder of 710.
The next digit of our result is 7. 
Result so far: 77635.7
Subtracting 6790 from 7500 leaves us with 710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7100, and continue the process.

Going ahead to step 10:
7100 divided by 970 is 7 with a remainder of 310.
Put 7 as the next digit of the answer. 
Result so far: 77635.77
If we subtract 6790 from 7100, we get 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

After the division, we end up with 77635.77 and a remainder of 0.31.
