91192048 ÷ 169 
The aim is to understand the frequency of 169 in 91192048.

Advancing to step 1:
The number 169 fits into 9 0 times, leaving a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Append the next digit (1) from the dividend to 9 and continue with: 91 / 169

Step 2:
If we divide 91 by 169, we get 0 and a remainder of 91.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 91 and we're left with 91.
Append the next digit (1) from the dividend to 91 and continue with: 911 / 169

Step 3:
When dividing 911 by 169, we get 5 with a remainder of 66.
Write down 5 as next digit of the result. 
Result so far: 5.0
The remainder is 66 after subtracting 845 from 911.
Take the next digit (9) from the dividend and append it to 66, then repeat: 669 / 169

Advancing to step 4:
The number 169 fits into 669 3 times, leaving a remainder of 162.
Use 3 as the next digit of our solution. 
Result so far: 53.0
Subtracting 507 from 669 leaves us with 162.
Fetch the next digit (2) from the dividend, attach it to 162 and continue: 1622 / 169

Going ahead to step 5:
When dividing 1622 by 169, we get 9 with a remainder of 101.
Put 9 as the next digit of the answer. 
Result so far: 539.0
If we take 1521 away from 1622, we end up with 101.
Bring next digit (0) of the dividend behind the 101 and repeat the process: 1010 / 169

On to step 6:
169 goes into 1010 5 times with a remainder of 165.
Put 5 as the next digit of the answer. 
Result so far: 5395.0
If we subtract 845 from 1010, we get 165.
Grab the next digit (4) from the dividend, add it to 165, then carry on: 1654 / 169

On to step 7:
The number 169 fits into 1654 9 times, leaving a remainder of 133.
Write down 9 as next digit of the result. 
Result so far: 53959.0
If we subtract 1521 from 1654, we get 133.
Include the next digit (8) from the dividend after 133, then repeat: 1338 / 169

Moving on to step 8:
1338 divided by 169 is 7 with a remainder of 155.
Record the quotient 7 as the next digit in the result. 
Result so far: 539597.0
If we take 1183 away from 1338, we end up with 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

Step 9:
If we divide 1550 by 169, we get 9 and a remainder of 29.
Write down 9 as next digit of the result. 
Result so far: 539597.9
Deduct 1521 from 1550 and we're left with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

On to step 10:
When dividing 290 by 169, we get 1 with a remainder of 121.
Use 1 as the next digit of our solution. 
Result so far: 539597.91
Subtracting 169 from 290 leaves us with 121.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1210, and continue the process.

Step 11:
169 goes into 1210 7 times with a remainder of 27.
Write down 7 as next digit of the result. 
Result so far: 539597.917
Subtract 1183 from 1210 to get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Moving on to step 12:
The number 169 fits into 270 1 times, leaving a remainder of 101.
The next digit of our result is 1. 
Result so far: 539597.9171
If we take 169 away from 270, we end up 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.

Let's proceed to step 13:
When dividing 1010 by 169, we get 5 with a remainder of 165.
The next digit of our result is 5. 
Result so far: 539597.91715
The remainder is 165 after subtracting 845 from 1010.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

Going ahead to step 14:
If we divide 1650 by 169, we get 9 and a remainder of 129.
The number 9 becomes the next digit in our result. 
Result so far: 539597.917159
If we subtract 1521 from 1650, we get 129.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1290, and continue the process.

Moving on to step 15:
The number 169 fits into 1290 7 times, leaving a remainder of 107.
Write down 7 as next digit of the result. 
Result so far: 539597.9171597
The remainder is 107 after subtracting 1183 from 1290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1070, and continue the process.

Step 16:
169 can be fit into 1070 6 times, resulting in a remainder of 56.
The number 6 becomes the next digit in our result. 
Result so far: 539597.91715976
Subtracting 1014 from 1070 leaves us 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 result is 539597.91715976 with a remainder of 5.6e-08.
