We look at the division of 1506480 by 975 
The aim is to understand the frequency of 975 in 1506480.

On to step 1:
1 divided by 975 is 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 975

Step 2:
15 divided by 975 is 0 with a remainder of 15.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 15, we get 15.
Include the next digit (0) from the dividend after 15, then repeat: 150 / 975

Going ahead to step 3:
When dividing 150 by 975, we get 0 with a remainder of 150.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 150, we end up with 150.
Include the next digit (6) from the dividend after 150, then repeat: 1506 / 975

On to step 4:
When dividing 1506 by 975, we get 1 with a remainder of 531.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 975 away from 1506, we end up with 531.
Bring next digit (4) of the dividend behind the 531 and repeat the process: 5314 / 975

Step 5:
975 goes into 5314 5 times with a remainder of 439.
Write down 5 as next digit of the result. 
Result so far: 15.0
Subtract 4875 from 5314 to get 439.
Grab the next digit (8) from the dividend, add it to 439, then carry on: 4398 / 975

Let's proceed to step 6:
975 can be fit into 4398 4 times, resulting in a remainder of 498.
Put 4 as the next digit of the answer. 
Result so far: 154.0
Subtract 3900 from 4398 to get 498.
Include the next digit (0) from the dividend after 498, then repeat: 4980 / 975

Let's proceed to step 7:
975 goes into 4980 5 times with a remainder of 105.
The number 5 becomes the next digit in our result. 
Result so far: 1545.0
If we subtract 4875 from 4980, we get 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Going ahead to step 8:
975 can be fit into 1050 1 times, resulting in a remainder of 75.
Put 1 as the next digit of the answer. 
Result so far: 1545.1
Subtracting 975 from 1050 leaves us with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Going ahead to step 9:
975 can be fit into 750 0 times, resulting in a remainder of 750.
Use 0 as the next digit of our solution. 
Result so far: 1545.1
The remainder is 750 after subtracting 0 from 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 10:
975 can be fit into 7500 7 times, resulting in a remainder of 675.
Put 7 as the next digit of the answer. 
Result so far: 1545.107
The remainder is 675 after subtracting 6825 from 7500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6750, and continue the process.

On to step 11:
When dividing 6750 by 975, we get 6 with a remainder of 900.
The number 6 becomes the next digit in our result. 
Result so far: 1545.1076
If we subtract 5850 from 6750, we get 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 12:
The number 975 fits into 9000 9 times, leaving a remainder of 225.
Put 9 as the next digit of the answer. 
Result so far: 1545.10769
If we take 8775 away from 9000, 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.

Advancing to step 13:
The number 975 fits into 2250 2 times, leaving a remainder of 300.
Record the quotient 2 as the next digit in the result. 
Result so far: 1545.107692
If we take 1950 away from 2250, we end up with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Moving on to step 14:
If we divide 3000 by 975, we get 3 and a remainder of 75.
Use 3 as the next digit of our solution. 
Result so far: 1545.1076923
The remainder is 75 after subtracting 2925 from 3000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Step 15:
750 divided by 975 is 0 with a remainder of 750.
The number 0 becomes the next digit in our result. 
Result so far: 1545.1076923
Subtracting 0 from 750 leaves us 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.

The quotient of the division is 1545.1076923, and the remainder is 7.5e-07.
