We look at the division of 3631184 by 169 
The aim is to understand the frequency of 169 in 3631184.

Step 1:
When dividing 3 by 169, we get 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Include the next digit (6) from the dividend after 3, then repeat: 36 / 169

Going ahead to step 2:
169 goes into 36 0 times with a remainder of 36.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 36 after subtracting 0 from 36.
Append the next digit (3) from the dividend to 36 and continue with: 363 / 169

Advancing to step 3:
363 divided by 169 is 2 with a remainder of 25.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtracting 338 from 363 leaves us with 25.
Bring next digit (1) of the dividend behind the 25 and repeat the process: 251 / 169

On to step 4:
251 divided by 169 is 1 with a remainder of 82.
Write down 1 as next digit of the result. 
Result so far: 21.0
If we subtract 169 from 251, we get 82.
Take the next digit (1) from the dividend and append it to 82, then repeat: 821 / 169

Let's proceed to step 5:
169 goes into 821 4 times with a remainder of 145.
Record the quotient 4 as the next digit in the result. 
Result so far: 214.0
Subtracting 676 from 821 leaves us with 145.
Append the next digit (8) from the dividend to 145 and continue with: 1458 / 169

Advancing to step 6:
1458 divided by 169 is 8 with a remainder of 106.
Write down 8 as next digit of the result. 
Result so far: 2148.0
Subtract 1352 from 1458 to get 106.
Take the next digit (4) from the dividend and append it to 106, then repeat: 1064 / 169

Moving on to step 7:
1064 divided by 169 is 6 with a remainder of 50.
Record the quotient 6 as the next digit in the result. 
Result so far: 21486.0
Deduct 1014 from 1064 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 8:
500 divided by 169 is 2 with a remainder of 162.
The number 2 becomes the next digit in our result. 
Result so far: 21486.2
Subtracting 338 from 500 leaves us with 162.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1620, and continue the process.

Step 9:
When dividing 1620 by 169, we get 9 with a remainder of 99.
Put 9 as the next digit of the answer. 
Result so far: 21486.29
If we take 1521 away from 1620, we end up with 99.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

Advancing to step 10:
The number 169 fits into 990 5 times, leaving a remainder of 145.
The next digit of our result is 5. 
Result so far: 21486.295
If we subtract 845 from 990, we get 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

On to step 11:
1450 divided by 169 is 8 with a remainder of 98.
Record the quotient 8 as the next digit in the result. 
Result so far: 21486.2958
Subtracting 1352 from 1450 leaves us with 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Let's proceed to step 12:
The number 169 fits into 980 5 times, leaving a remainder of 135.
The next digit of our result is 5. 
Result so far: 21486.29585
If we take 845 away from 980, we end up with 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Going ahead to step 13:
The number 169 fits into 1350 7 times, leaving a remainder of 167.
The next digit of our result is 7. 
Result so far: 21486.295857
Deduct 1183 from 1350 and we're left with 167.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1670, and continue the process.

Advancing to step 14:
169 goes into 1670 9 times with a remainder of 149.
Write down 9 as next digit of the result. 
Result so far: 21486.2958579
Deduct 1521 from 1670 and we're left with 149.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1490, and continue the process.

Going ahead to step 15:
If we divide 1490 by 169, we get 8 and a remainder of 138.
Use 8 as the next digit of our solution. 
Result so far: 21486.29585798
If we take 1352 away from 1490, we end up with 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

Our division results in 21486.29585798 with a remaining 1.38e-07.
