Let's divide 87758358 by 975
The aim is to understand the frequency of 975 in 87758358.

Going ahead to step 1:
If we divide 8 by 975, we get 0 and a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Bring next digit (7) of the dividend behind the 8 and repeat the process: 87 / 975

Going ahead to step 2:
The number 975 fits into 87 0 times, leaving a remainder of 87.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 87 leaves us with 87.
Append the next digit (7) from the dividend to 87 and continue with: 877 / 975

On to step 3:
When dividing 877 by 975, we get 0 with a remainder of 877.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 877 leaves us with 877.
Append the next digit (5) from the dividend to 877 and continue with: 8775 / 975

Advancing to step 4:
The number 975 fits into 8775 9 times, leaving a remainder of 0.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
If we take 8775 away from 8775, we end up with 0.
Grab the next digit (8) from the dividend, add it to 0, then carry on: 8 / 975

Moving on to step 5:
975 goes into 8 0 times with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 90.0
Deduct 0 from 8 and we're left with 8.
Fetch the next digit (3) from the dividend, attach it to 8 and continue: 83 / 975

On to step 6:
When dividing 83 by 975, we get 0 with a remainder of 83.
Put 0 as the next digit of the answer. 
Result so far: 900.0
If we subtract 0 from 83, we get 83.
Fetch the next digit (5) from the dividend, attach it to 83 and continue: 835 / 975

Moving on to step 7:
The number 975 fits into 835 0 times, leaving a remainder of 835.
Use 0 as the next digit of our solution. 
Result so far: 9000.0
The remainder is 835 after subtracting 0 from 835.
Fetch the next digit (8) from the dividend, attach it to 835 and continue: 8358 / 975

Step 8:
975 goes into 8358 8 times with a remainder of 558.
The next digit of our result is 8. 
Result so far: 90008.0
The remainder is 558 after subtracting 7800 from 8358.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5580, and continue the process.

On to step 9:
The number 975 fits into 5580 5 times, leaving a remainder of 705.
Record the quotient 5 as the next digit in the result. 
Result so far: 90008.5
Deduct 4875 from 5580 and we're left with 705.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7050, and continue the process.

Let's proceed to step 10:
7050 divided by 975 is 7 with a remainder of 225.
Write down 7 as next digit of the result. 
Result so far: 90008.57
If we take 6825 away from 7050, we end up with 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

Step 11:
975 can be fit into 2250 2 times, resulting in a remainder of 300.
Use 2 as the next digit of our solution. 
Result so far: 90008.572
The remainder is 300 after subtracting 1950 from 2250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Advancing to step 12:
975 goes into 3000 3 times with a remainder of 75.
Record the quotient 3 as the next digit in the result. 
Result so far: 90008.5723
If we subtract 2925 from 3000, we get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Moving on to step 13:
975 can be fit into 750 0 times, resulting in a remainder of 750.
Record the quotient 0 as the next digit in the result. 
Result so far: 90008.5723
If we take 0 away from 750, we end up 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.

Advancing to step 14:
975 goes into 7500 7 times with a remainder of 675.
The next digit of our result is 7. 
Result so far: 90008.572307
Deduct 6825 from 7500 and we're left with 675.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6750, and continue the process.

Moving on to step 15:
975 can be fit into 6750 6 times, resulting in a remainder of 900.
Record the quotient 6 as the next digit in the result. 
Result so far: 90008.5723076
Deduct 5850 from 6750 and we're left with 900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9000, and continue the process.

Step 16:
If we divide 9000 by 975, we get 9 and a remainder of 225.
Record the quotient 9 as the next digit in the result. 
Result so far: 90008.57230769
The remainder is 225 after subtracting 8775 from 9000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

The final result is 90008.57230769 with a remainder of 2.25e-07.
