Let's divide 12622586 by 748
The aim is to understand the frequency of 748 in 12622586.

Advancing to step 1:
748 can be fit into 1 0 times, resulting in a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 748

Going ahead to step 2:
12 divided by 748 is 0 with a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 12 after subtracting 0 from 12.
Take the next digit (6) from the dividend and append it to 12, then repeat: 126 / 748

Step 3:
126 divided by 748 is 0 with a remainder of 126.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 126 to get 126.
Grab the next digit (2) from the dividend, add it to 126, then carry on: 1262 / 748

Going ahead to step 4:
When dividing 1262 by 748, we get 1 with a remainder of 514.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 748 from 1262, we get 514.
Fetch the next digit (2) from the dividend, attach it to 514 and continue: 5142 / 748

Moving on to step 5:
5142 divided by 748 is 6 with a remainder of 654.
Put 6 as the next digit of the answer. 
Result so far: 16.0
If we subtract 4488 from 5142, we get 654.
Append the next digit (5) from the dividend to 654 and continue with: 6545 / 748

Going ahead to step 6:
The number 748 fits into 6545 8 times, leaving a remainder of 561.
Put 8 as the next digit of the answer. 
Result so far: 168.0
If we subtract 5984 from 6545, we get 561.
Fetch the next digit (8) from the dividend, attach it to 561 and continue: 5618 / 748

Let's proceed to step 7:
When dividing 5618 by 748, we get 7 with a remainder of 382.
Write down 7 as next digit of the result. 
Result so far: 1687.0
If we take 5236 away from 5618, we end up with 382.
Take the next digit (6) from the dividend and append it to 382, then repeat: 3826 / 748

Let's proceed to step 8:
748 can be fit into 3826 5 times, resulting in a remainder of 86.
The next digit of our result is 5. 
Result so far: 16875.0
If we take 3740 away from 3826, we end up with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Step 9:
If we divide 860 by 748, we get 1 and a remainder of 112.
Record the quotient 1 as the next digit in the result. 
Result so far: 16875.1
The remainder is 112 after subtracting 748 from 860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Advancing to step 10:
748 can be fit into 1120 1 times, resulting in a remainder of 372.
Record the quotient 1 as the next digit in the result. 
Result so far: 16875.11
If we subtract 748 from 1120, we get 372.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3720, and continue the process.

The final outcome is 16875.11, with a leftover of 0.372.
