We're dividing 86850997 by 429 
The aim is to understand the frequency of 429 in 86850997.

Moving on to step 1:
429 goes into 8 0 times with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 429

Moving on to step 2:
429 can be fit into 86 0 times, resulting in a remainder of 86.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 86 to get 86.
Fetch the next digit (8) from the dividend, attach it to 86 and continue: 868 / 429

Moving on to step 3:
If we divide 868 by 429, we get 2 and a remainder of 10.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
The remainder is 10 after subtracting 858 from 868.
Bring next digit (5) of the dividend behind the 10 and repeat the process: 105 / 429

Step 4:
429 can be fit into 105 0 times, resulting in a remainder of 105.
Put 0 as the next digit of the answer. 
Result so far: 20.0
The remainder is 105 after subtracting 0 from 105.
Fetch the next digit (0) from the dividend, attach it to 105 and continue: 1050 / 429

Moving on to step 5:
429 goes into 1050 2 times with a remainder of 192.
Use 2 as the next digit of our solution. 
Result so far: 202.0
Subtract 858 from 1050 to get 192.
Fetch the next digit (9) from the dividend, attach it to 192 and continue: 1929 / 429

Step 6:
If we divide 1929 by 429, we get 4 and a remainder of 213.
The number 4 becomes the next digit in our result. 
Result so far: 2024.0
Deduct 1716 from 1929 and we're left with 213.
Take the next digit (9) from the dividend and append it to 213, then repeat: 2139 / 429

Step 7:
When dividing 2139 by 429, we get 4 with a remainder of 423.
Put 4 as the next digit of the answer. 
Result so far: 20244.0
Subtracting 1716 from 2139 leaves us with 423.
Append the next digit (7) from the dividend to 423 and continue with: 4237 / 429

Moving on to step 8:
The number 429 fits into 4237 9 times, leaving a remainder of 376.
Record the quotient 9 as the next digit in the result. 
Result so far: 202449.0
Deduct 3861 from 4237 and we're left with 376.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

Step 9:
When dividing 3760 by 429, we get 8 with a remainder of 328.
Write down 8 as next digit of the result. 
Result so far: 202449.8
The remainder is 328 after subtracting 3432 from 3760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

Step 10:
3280 divided by 429 is 7 with a remainder of 277.
Use 7 as the next digit of our solution. 
Result so far: 202449.87
If we subtract 3003 from 3280, we get 277.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2770, and continue the process.

Step 11:
429 goes into 2770 6 times with a remainder of 196.
The next digit of our result is 6. 
Result so far: 202449.876
If we take 2574 away from 2770, we end up with 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

Step 12:
1960 divided by 429 is 4 with a remainder of 244.
Write down 4 as next digit of the result. 
Result so far: 202449.8764
If we take 1716 away from 1960, we end up with 244.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

Going ahead to step 13:
429 can be fit into 2440 5 times, resulting in a remainder of 295.
Use 5 as the next digit of our solution. 
Result so far: 202449.87645
If we subtract 2145 from 2440, we get 295.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2950, and continue the process.

Going ahead to step 14:
The number 429 fits into 2950 6 times, leaving a remainder of 376.
Use 6 as the next digit of our solution. 
Result so far: 202449.876456
If we take 2574 away from 2950, we end up with 376.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

Moving on to step 15:
429 goes into 3760 8 times with a remainder of 328.
The next digit of our result is 8. 
Result so far: 202449.8764568
Subtracting 3432 from 3760 leaves us with 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

Moving on to step 16:
The number 429 fits into 3280 7 times, leaving a remainder of 277.
Write down 7 as next digit of the result. 
Result so far: 202449.87645687
If we subtract 3003 from 3280, we get 277.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2770, and continue the process.

The final result is 202449.87645687 with a remainder of 2.77e-07.
