88628253 divided by 974 
The aim is to understand the frequency of 974 in 88628253.

Moving on to step 1:
974 goes into 8 0 times with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Take the next digit (8) from the dividend and append it to 8, then repeat: 88 / 974

On to step 2:
The number 974 fits into 88 0 times, leaving a remainder of 88.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 88, we get 88.
Grab the next digit (6) from the dividend, add it to 88, then carry on: 886 / 974

Step 3:
974 can be fit into 886 0 times, resulting in a remainder of 886.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 886 after subtracting 0 from 886.
Include the next digit (2) from the dividend after 886, then repeat: 8862 / 974

Going ahead to step 4:
The number 974 fits into 8862 9 times, leaving a remainder of 96.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Subtracting 8766 from 8862 leaves us with 96.
Fetch the next digit (8) from the dividend, attach it to 96 and continue: 968 / 974

Advancing to step 5:
968 divided by 974 is 0 with a remainder of 968.
Use 0 as the next digit of our solution. 
Result so far: 90.0
The remainder is 968 after subtracting 0 from 968.
Bring next digit (2) of the dividend behind the 968 and repeat the process: 9682 / 974

Step 6:
If we divide 9682 by 974, we get 9 and a remainder of 916.
Put 9 as the next digit of the answer. 
Result so far: 909.0
Deduct 8766 from 9682 and we're left with 916.
Bring next digit (5) of the dividend behind the 916 and repeat the process: 9165 / 974

Advancing to step 7:
9165 divided by 974 is 9 with a remainder of 399.
Put 9 as the next digit of the answer. 
Result so far: 9099.0
If we subtract 8766 from 9165, we get 399.
Include the next digit (3) from the dividend after 399, then repeat: 3993 / 974

Let's proceed to step 8:
3993 divided by 974 is 4 with a remainder of 97.
The next digit of our result is 4. 
Result so far: 90994.0
The remainder is 97 after subtracting 3896 from 3993.
Since there are no more digits in the dividend, we add a zero to the remainder making it 970, and continue the process.

Step 9:
974 can be fit into 970 0 times, resulting in a remainder of 970.
The next digit of our result is 0. 
Result so far: 90994.0
Deduct 0 from 970 and we're left with 970.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9700, and continue the process.

On to step 10:
The number 974 fits into 9700 9 times, leaving a remainder of 934.
Put 9 as the next digit of the answer. 
Result so far: 90994.09
Deduct 8766 from 9700 and we're left with 934.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9340, and continue the process.

On to step 11:
If we divide 9340 by 974, we get 9 and a remainder of 574.
The number 9 becomes the next digit in our result. 
Result so far: 90994.099
If we subtract 8766 from 9340, we get 574.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5740, and continue the process.

After the division, we end up with 90994.099 and a remainder of 0.0574.
