We look at the division of 17713630 by 161 
The aim is to understand the frequency of 161 in 17713630.

Moving on to step 1:
161 can be fit into 1 0 times, resulting in a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Append the next digit (7) from the dividend to 1 and continue with: 17 / 161

Going ahead to step 2:
17 divided by 161 is 0 with a remainder of 17.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 17 to get 17.
Bring next digit (7) of the dividend behind the 17 and repeat the process: 177 / 161

On to step 3:
177 divided by 161 is 1 with a remainder of 16.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 161 from 177, we get 16.
Append the next digit (1) from the dividend to 16 and continue with: 161 / 161

Going ahead to step 4:
161 divided by 161 is 1 with a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
If we subtract 161 from 161, we get 0.
Bring next digit (3) of the dividend behind the 0 and repeat the process: 3 / 161

Moving on to step 5:
161 goes into 3 0 times with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 110.0
Subtracting 0 from 3 leaves us with 3.
Grab the next digit (6) from the dividend, add it to 3, then carry on: 36 / 161

On to step 6:
If we divide 36 by 161, we get 0 and a remainder of 36.
Record the quotient 0 as the next digit in the result. 
Result so far: 1100.0
The remainder is 36 after subtracting 0 from 36.
Include the next digit (3) from the dividend after 36, then repeat: 363 / 161

Going ahead to step 7:
If we divide 363 by 161, we get 2 and a remainder of 41.
Write down 2 as next digit of the result. 
Result so far: 11002.0
The remainder is 41 after subtracting 322 from 363.
Include the next digit (0) from the dividend after 41, then repeat: 410 / 161

On to step 8:
161 can be fit into 410 2 times, resulting in a remainder of 88.
The next digit of our result is 2. 
Result so far: 110022.0
The remainder is 88 after subtracting 322 from 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Going ahead to step 9:
880 divided by 161 is 5 with a remainder of 75.
Put 5 as the next digit of the answer. 
Result so far: 110022.5
If we subtract 805 from 880, we get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Moving on to step 10:
The number 161 fits into 750 4 times, leaving a remainder of 106.
Put 4 as the next digit of the answer. 
Result so far: 110022.54
Subtracting 644 from 750 leaves us with 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Advancing to step 11:
If we divide 1060 by 161, we get 6 and a remainder of 94.
The next digit of our result is 6. 
Result so far: 110022.546
Subtract 966 from 1060 to get 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Moving on to step 12:
If we divide 940 by 161, we get 5 and a remainder of 135.
Use 5 as the next digit of our solution. 
Result so far: 110022.5465
If we subtract 805 from 940, we get 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Step 13:
1350 divided by 161 is 8 with a remainder of 62.
Put 8 as the next digit of the answer. 
Result so far: 110022.54658
The remainder is 62 after subtracting 1288 from 1350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Moving on to step 14:
If we divide 620 by 161, we get 3 and a remainder of 137.
Use 3 as the next digit of our solution. 
Result so far: 110022.546583
Deduct 483 from 620 and we're left with 137.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1370, and continue the process.

On to step 15:
If we divide 1370 by 161, we get 8 and a remainder of 82.
Write down 8 as next digit of the result. 
Result so far: 110022.5465838
Deduct 1288 from 1370 and we're left with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Step 16:
The number 161 fits into 820 5 times, leaving a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 110022.54658385
If we take 805 away from 820, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

In conclusion, the division gives 110022.54658385 with a balance of 1.5e-08.
