We look at the division of 52106690 by 163 
The aim is to understand the frequency of 163 in 52106690.

Going ahead to step 1:
If we divide 5 by 163, we get 0 and a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Fetch the next digit (2) from the dividend, attach it to 5 and continue: 52 / 163

Step 2:
When dividing 52 by 163, we get 0 with a remainder of 52.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 52 leaves us with 52.
Fetch the next digit (1) from the dividend, attach it to 52 and continue: 521 / 163

Advancing to step 3:
521 divided by 163 is 3 with a remainder of 32.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Deduct 489 from 521 and we're left with 32.
Append the next digit (0) from the dividend to 32 and continue with: 320 / 163

Advancing to step 4:
163 goes into 320 1 times with a remainder of 157.
Use 1 as the next digit of our solution. 
Result so far: 31.0
Subtract 163 from 320 to get 157.
Fetch the next digit (6) from the dividend, attach it to 157 and continue: 1576 / 163

Advancing to step 5:
163 can be fit into 1576 9 times, resulting in a remainder of 109.
The number 9 becomes the next digit in our result. 
Result so far: 319.0
Subtracting 1467 from 1576 leaves us with 109.
Grab the next digit (6) from the dividend, add it to 109, then carry on: 1096 / 163

Step 6:
163 goes into 1096 6 times with a remainder of 118.
The next digit of our result is 6. 
Result so far: 3196.0
The remainder is 118 after subtracting 978 from 1096.
Append the next digit (9) from the dividend to 118 and continue with: 1189 / 163

Advancing to step 7:
The number 163 fits into 1189 7 times, leaving a remainder of 48.
Put 7 as the next digit of the answer. 
Result so far: 31967.0
Subtracting 1141 from 1189 leaves us with 48.
Append the next digit (0) from the dividend to 48 and continue with: 480 / 163

On to step 8:
163 can be fit into 480 2 times, resulting in a remainder of 154.
Record the quotient 2 as the next digit in the result. 
Result so far: 319672.0
If we subtract 326 from 480, we get 154.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

Let's proceed to step 9:
The number 163 fits into 1540 9 times, leaving a remainder of 73.
Write down 9 as next digit of the result. 
Result so far: 319672.9
Subtract 1467 from 1540 to get 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Moving on to step 10:
If we divide 730 by 163, we get 4 and a remainder of 78.
Use 4 as the next digit of our solution. 
Result so far: 319672.94
If we subtract 652 from 730, we get 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Step 11:
If we divide 780 by 163, we get 4 and a remainder of 128.
Write down 4 as next digit of the result. 
Result so far: 319672.944
The remainder is 128 after subtracting 652 from 780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

The final result is 319672.944 with a remainder of 0.0128.
