We look at the division of 39473380 by 975 
The aim is to understand the frequency of 975 in 39473380.

Moving on to step 1:
When dividing 3 by 975, we get 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 975

Going ahead to step 2:
The number 975 fits into 39 0 times, leaving a remainder of 39.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 39 to get 39.
Bring next digit (4) of the dividend behind the 39 and repeat the process: 394 / 975

Moving on to step 3:
The number 975 fits into 394 0 times, leaving a remainder of 394.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 394 to get 394.
Fetch the next digit (7) from the dividend, attach it to 394 and continue: 3947 / 975

Advancing to step 4:
When dividing 3947 by 975, we get 4 with a remainder of 47.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we take 3900 away from 3947, we end up with 47.
Take the next digit (3) from the dividend and append it to 47, then repeat: 473 / 975

Step 5:
If we divide 473 by 975, we get 0 and a remainder of 473.
Write down 0 as next digit of the result. 
Result so far: 40.0
Deduct 0 from 473 and we're left with 473.
Include the next digit (3) from the dividend after 473, then repeat: 4733 / 975

Step 6:
When dividing 4733 by 975, we get 4 with a remainder of 833.
Put 4 as the next digit of the answer. 
Result so far: 404.0
If we subtract 3900 from 4733, we get 833.
Bring next digit (8) of the dividend behind the 833 and repeat the process: 8338 / 975

On to step 7:
The number 975 fits into 8338 8 times, leaving a remainder of 538.
Write down 8 as next digit of the result. 
Result so far: 4048.0
If we subtract 7800 from 8338, we get 538.
Fetch the next digit (0) from the dividend, attach it to 538 and continue: 5380 / 975

On to step 8:
When dividing 5380 by 975, we get 5 with a remainder of 505.
Record the quotient 5 as the next digit in the result. 
Result so far: 40485.0
If we take 4875 away from 5380, we end up with 505.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5050, and continue the process.

Going ahead to step 9:
975 can be fit into 5050 5 times, resulting in a remainder of 175.
Write down 5 as next digit of the result. 
Result so far: 40485.5
The remainder is 175 after subtracting 4875 from 5050.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Let's proceed to step 10:
975 can be fit into 1750 1 times, resulting in a remainder of 775.
Put 1 as the next digit of the answer. 
Result so far: 40485.51
Subtracting 975 from 1750 leaves us with 775.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7750, and continue the process.

Step 11:
The number 975 fits into 7750 7 times, leaving a remainder of 925.
Put 7 as the next digit of the answer. 
Result so far: 40485.517
Deduct 6825 from 7750 and we're left with 925.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9250, and continue the process.

On to step 12:
If we divide 9250 by 975, we get 9 and a remainder of 475.
Record the quotient 9 as the next digit in the result. 
Result so far: 40485.5179
If we subtract 8775 from 9250, we get 475.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4750, and continue the process.

Moving on to step 13:
When dividing 4750 by 975, we get 4 with a remainder of 850.
Record the quotient 4 as the next digit in the result. 
Result so far: 40485.51794
Subtracting 3900 from 4750 leaves us with 850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8500, and continue the process.

Let's proceed to step 14:
When dividing 8500 by 975, we get 8 with a remainder of 700.
Write down 8 as next digit of the result. 
Result so far: 40485.517948
Subtracting 7800 from 8500 leaves us with 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

Advancing to step 15:
The number 975 fits into 7000 7 times, leaving a remainder of 175.
Use 7 as the next digit of our solution. 
Result so far: 40485.5179487
If we subtract 6825 from 7000, we get 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Going ahead to step 16:
975 goes into 1750 1 times with a remainder of 775.
The number 1 becomes the next digit in our result. 
Result so far: 40485.51794871
If we take 975 away from 1750, we end up with 775.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7750, and continue the process.

The final outcome is 40485.51794871, with a leftover of 7.75e-07.
