We look at the division of 81626061 by 104 
The aim is to understand the frequency of 104 in 81626061.

Going ahead to step 1:
If we divide 8 by 104, we get 0 and a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 104

Let's proceed to step 2:
104 goes into 81 0 times with a remainder of 81.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 81 and we're left with 81.
Grab the next digit (6) from the dividend, add it to 81, then carry on: 816 / 104

Step 3:
104 can be fit into 816 7 times, resulting in a remainder of 88.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
The remainder is 88 after subtracting 728 from 816.
Take the next digit (2) from the dividend and append it to 88, then repeat: 882 / 104

On to step 4:
If we divide 882 by 104, we get 8 and a remainder of 50.
Record the quotient 8 as the next digit in the result. 
Result so far: 78.0
The remainder is 50 after subtracting 832 from 882.
Take the next digit (6) from the dividend and append it to 50, then repeat: 506 / 104

On to step 5:
104 goes into 506 4 times with a remainder of 90.
The number 4 becomes the next digit in our result. 
Result so far: 784.0
If we subtract 416 from 506, we get 90.
Append the next digit (0) from the dividend to 90 and continue with: 900 / 104

On to step 6:
If we divide 900 by 104, we get 8 and a remainder of 68.
Record the quotient 8 as the next digit in the result. 
Result so far: 7848.0
If we subtract 832 from 900, we get 68.
Bring next digit (6) of the dividend behind the 68 and repeat the process: 686 / 104

Step 7:
104 goes into 686 6 times with a remainder of 62.
The number 6 becomes the next digit in our result. 
Result so far: 78486.0
The remainder is 62 after subtracting 624 from 686.
Take the next digit (1) from the dividend and append it to 62, then repeat: 621 / 104

Let's proceed to step 8:
The number 104 fits into 621 5 times, leaving a remainder of 101.
The next digit of our result is 5. 
Result so far: 784865.0
Subtracting 520 from 621 leaves us with 101.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1010, and continue the process.

Step 9:
If we divide 1010 by 104, we get 9 and a remainder of 74.
Record the quotient 9 as the next digit in the result. 
Result so far: 784865.9
Subtract 936 from 1010 to get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Let's proceed to step 10:
If we divide 740 by 104, we get 7 and a remainder of 12.
Put 7 as the next digit of the answer. 
Result so far: 784865.97
Subtracting 728 from 740 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 11:
104 can be fit into 120 1 times, resulting in a remainder of 16.
Put 1 as the next digit of the answer. 
Result so far: 784865.971
Deduct 104 from 120 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 12:
When dividing 160 by 104, we get 1 with a remainder of 56.
Write down 1 as next digit of the result. 
Result so far: 784865.9711
Deduct 104 from 160 and we're left with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

The final outcome is 784865.9711, with a leftover of 0.00056.
