We're dividing 86488106 by 423 
The aim is to understand the frequency of 423 in 86488106.

Moving on to step 1:
The number 423 fits into 8 0 times, leaving a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 423

Step 2:
86 divided by 423 is 0 with a remainder of 86.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 86 after subtracting 0 from 86.
Take the next digit (4) from the dividend and append it to 86, then repeat: 864 / 423

Moving on to step 3:
When dividing 864 by 423, we get 2 with a remainder of 18.
The next digit of our result is 2. 
Result so far: 2.0
Deduct 846 from 864 and we're left with 18.
Take the next digit (8) from the dividend and append it to 18, then repeat: 188 / 423

Advancing to step 4:
423 goes into 188 0 times with a remainder of 188.
Use 0 as the next digit of our solution. 
Result so far: 20.0
Subtracting 0 from 188 leaves us with 188.
Bring next digit (8) of the dividend behind the 188 and repeat the process: 1888 / 423

Going ahead to step 5:
423 can be fit into 1888 4 times, resulting in a remainder of 196.
The number 4 becomes the next digit in our result. 
Result so far: 204.0
Subtract 1692 from 1888 to get 196.
Grab the next digit (1) from the dividend, add it to 196, then carry on: 1961 / 423

Moving on to step 6:
423 can be fit into 1961 4 times, resulting in a remainder of 269.
The number 4 becomes the next digit in our result. 
Result so far: 2044.0
Deduct 1692 from 1961 and we're left with 269.
Take the next digit (0) from the dividend and append it to 269, then repeat: 2690 / 423

On to step 7:
When dividing 2690 by 423, we get 6 with a remainder of 152.
The number 6 becomes the next digit in our result. 
Result so far: 20446.0
Deduct 2538 from 2690 and we're left with 152.
Append the next digit (6) from the dividend to 152 and continue with: 1526 / 423

Step 8:
When dividing 1526 by 423, we get 3 with a remainder of 257.
The next digit of our result is 3. 
Result so far: 204463.0
Subtract 1269 from 1526 to get 257.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2570, and continue the process.

Step 9:
2570 divided by 423 is 6 with a remainder of 32.
The number 6 becomes the next digit in our result. 
Result so far: 204463.6
The remainder is 32 after subtracting 2538 from 2570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 10:
423 goes into 320 0 times with a remainder of 320.
Record the quotient 0 as the next digit in the result. 
Result so far: 204463.6
Subtract 0 from 320 to get 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Let's proceed to step 11:
When dividing 3200 by 423, we get 7 with a remainder of 239.
Use 7 as the next digit of our solution. 
Result so far: 204463.607
The remainder is 239 after subtracting 2961 from 3200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2390, and continue the process.

Moving on to step 12:
423 can be fit into 2390 5 times, resulting in a remainder of 275.
The next digit of our result is 5. 
Result so far: 204463.6075
Deduct 2115 from 2390 and we're left with 275.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

Going ahead to step 13:
If we divide 2750 by 423, we get 6 and a remainder of 212.
Record the quotient 6 as the next digit in the result. 
Result so far: 204463.60756
Subtract 2538 from 2750 to get 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

On to step 14:
423 can be fit into 2120 5 times, resulting in a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 204463.607565
Subtracting 2115 from 2120 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 15:
423 can be fit into 50 0 times, resulting in a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 204463.607565
If we subtract 0 from 50, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 16:
423 goes into 500 1 times with a remainder of 77.
The number 1 becomes the next digit in our result. 
Result so far: 204463.60756501
Subtract 423 from 500 to get 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

After the division, we end up with 204463.60756501 and a remainder of 7.7e-08.
