We look at the division of 89074557 by 972 
The aim is to understand the frequency of 972 in 89074557.

Advancing to step 1:
If we divide 8 by 972, we get 0 and a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Append the next digit (9) from the dividend to 8 and continue with: 89 / 972

Step 2:
972 can be fit into 89 0 times, resulting in a remainder of 89.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 89, we end up with 89.
Take the next digit (0) from the dividend and append it to 89, then repeat: 890 / 972

Step 3:
890 divided by 972 is 0 with a remainder of 890.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 890, we end up with 890.
Bring next digit (7) of the dividend behind the 890 and repeat the process: 8907 / 972

Advancing to step 4:
972 goes into 8907 9 times with a remainder of 159.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Deduct 8748 from 8907 and we're left with 159.
Take the next digit (4) from the dividend and append it to 159, then repeat: 1594 / 972

Let's proceed to step 5:
972 goes into 1594 1 times with a remainder of 622.
Write down 1 as next digit of the result. 
Result so far: 91.0
The remainder is 622 after subtracting 972 from 1594.
Bring next digit (5) of the dividend behind the 622 and repeat the process: 6225 / 972

Step 6:
6225 divided by 972 is 6 with a remainder of 393.
Put 6 as the next digit of the answer. 
Result so far: 916.0
Deduct 5832 from 6225 and we're left with 393.
Fetch the next digit (5) from the dividend, attach it to 393 and continue: 3935 / 972

Let's proceed to step 7:
When dividing 3935 by 972, we get 4 with a remainder of 47.
The next digit of our result is 4. 
Result so far: 9164.0
The remainder is 47 after subtracting 3888 from 3935.
Include the next digit (7) from the dividend after 47, then repeat: 477 / 972

Let's proceed to step 8:
972 can be fit into 477 0 times, resulting in a remainder of 477.
Record the quotient 0 as the next digit in the result. 
Result so far: 91640.0
Deduct 0 from 477 and we're left with 477.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4770, and continue the process.

Step 9:
972 can be fit into 4770 4 times, resulting in a remainder of 882.
Use 4 as the next digit of our solution. 
Result so far: 91640.4
Subtract 3888 from 4770 to get 882.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8820, and continue the process.

On to step 10:
If we divide 8820 by 972, we get 9 and a remainder of 72.
The next digit of our result is 9. 
Result so far: 91640.49
If we take 8748 away from 8820, we end up with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Going ahead to step 11:
972 can be fit into 720 0 times, resulting in a remainder of 720.
The next digit of our result is 0. 
Result so far: 91640.49
Subtract 0 from 720 to get 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7200, and continue the process.

Let's proceed to step 12:
972 can be fit into 7200 7 times, resulting in a remainder of 396.
Use 7 as the next digit of our solution. 
Result so far: 91640.4907
The remainder is 396 after subtracting 6804 from 7200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3960, and continue the process.

On to step 13:
When dividing 3960 by 972, we get 4 with a remainder of 72.
The number 4 becomes the next digit in our result. 
Result so far: 91640.49074
The remainder is 72 after subtracting 3888 from 3960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Going ahead to step 14:
972 goes into 720 0 times with a remainder of 720.
The next digit of our result is 0. 
Result so far: 91640.49074
If we take 0 away from 720, we end up with 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7200, and continue the process.

Going ahead to step 15:
If we divide 7200 by 972, we get 7 and a remainder of 396.
Record the quotient 7 as the next digit in the result. 
Result so far: 91640.4907407
The remainder is 396 after subtracting 6804 from 7200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3960, and continue the process.

Moving on to step 16:
When dividing 3960 by 972, we get 4 with a remainder of 72.
The next digit of our result is 4. 
Result so far: 91640.49074074
The remainder is 72 after subtracting 3888 from 3960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Our division results in 91640.49074074 with a remaining 7.2e-08.
