We look at the division of 12400250 by 976 
The aim is to understand the frequency of 976 in 12400250.

Moving on to step 1:
When dividing 1 by 976, we get 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 976

Moving on to step 2:
The number 976 fits into 12 0 times, leaving a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 12 after subtracting 0 from 12.
Grab the next digit (4) from the dividend, add it to 12, then carry on: 124 / 976

Step 3:
The number 976 fits into 124 0 times, leaving a remainder of 124.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 124 leaves us with 124.
Append the next digit (0) from the dividend to 124 and continue with: 1240 / 976

On to step 4:
If we divide 1240 by 976, we get 1 and a remainder of 264.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 976 from 1240, we get 264.
Take the next digit (0) from the dividend and append it to 264, then repeat: 2640 / 976

Let's proceed to step 5:
If we divide 2640 by 976, we get 2 and a remainder of 688.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
Subtract 1952 from 2640 to get 688.
Take the next digit (2) from the dividend and append it to 688, then repeat: 6882 / 976

Let's proceed to step 6:
The number 976 fits into 6882 7 times, leaving a remainder of 50.
The number 7 becomes the next digit in our result. 
Result so far: 127.0
If we take 6832 away from 6882, we end up with 50.
Grab the next digit (5) from the dividend, add it to 50, then carry on: 505 / 976

Step 7:
505 divided by 976 is 0 with a remainder of 505.
Write down 0 as next digit of the result. 
Result so far: 1270.0
The remainder is 505 after subtracting 0 from 505.
Fetch the next digit (0) from the dividend, attach it to 505 and continue: 5050 / 976

Moving on to step 8:
If we divide 5050 by 976, we get 5 and a remainder of 170.
The number 5 becomes the next digit in our result. 
Result so far: 12705.0
If we take 4880 away from 5050, we end up with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Let's proceed to step 9:
1700 divided by 976 is 1 with a remainder of 724.
Put 1 as the next digit of the answer. 
Result so far: 12705.1
The remainder is 724 after subtracting 976 from 1700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7240, and continue the process.

Moving on to step 10:
976 can be fit into 7240 7 times, resulting in a remainder of 408.
The next digit of our result is 7. 
Result so far: 12705.17
Subtract 6832 from 7240 to get 408.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4080, and continue the process.

Moving on to step 11:
976 can be fit into 4080 4 times, resulting in a remainder of 176.
Record the quotient 4 as the next digit in the result. 
Result so far: 12705.174
If we take 3904 away from 4080, we end up with 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Let's proceed to step 12:
If we divide 1760 by 976, we get 1 and a remainder of 784.
Use 1 as the next digit of our solution. 
Result so far: 12705.1741
If we take 976 away from 1760, we end up with 784.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7840, and continue the process.

On to step 13:
7840 divided by 976 is 8 with a remainder of 32.
The next digit of our result is 8. 
Result so far: 12705.17418
Subtracting 7808 from 7840 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 14:
976 can be fit into 320 0 times, resulting in a remainder of 320.
Write down 0 as next digit of the result. 
Result so far: 12705.17418
Subtracting 0 from 320 leaves us with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Moving on to step 15:
976 goes into 3200 3 times with a remainder of 272.
Write down 3 as next digit of the result. 
Result so far: 12705.1741803
Subtracting 2928 from 3200 leaves us with 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

Let's proceed to step 16:
When dividing 2720 by 976, we get 2 with a remainder of 768.
Use 2 as the next digit of our solution. 
Result so far: 12705.17418032
If we take 1952 away from 2720, we end up with 768.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7680, and continue the process.

After the division, we end up with 12705.17418032 and a remainder of 7.68e-07.
