We're dividing 78205210 by 429 
The aim is to understand the frequency of 429 in 78205210.

Going ahead to step 1:
7 divided by 429 is 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 429

Let's proceed to step 2:
The number 429 fits into 78 0 times, leaving a remainder of 78.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 78 after subtracting 0 from 78.
Fetch the next digit (2) from the dividend, attach it to 78 and continue: 782 / 429

Step 3:
When dividing 782 by 429, we get 1 with a remainder of 353.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 353 after subtracting 429 from 782.
Grab the next digit (0) from the dividend, add it to 353, then carry on: 3530 / 429

Advancing to step 4:
When dividing 3530 by 429, we get 8 with a remainder of 98.
The next digit of our result is 8. 
Result so far: 18.0
Deduct 3432 from 3530 and we're left with 98.
Grab the next digit (5) from the dividend, add it to 98, then carry on: 985 / 429

Moving on to step 5:
985 divided by 429 is 2 with a remainder of 127.
Write down 2 as next digit of the result. 
Result so far: 182.0
If we subtract 858 from 985, we get 127.
Bring next digit (2) of the dividend behind the 127 and repeat the process: 1272 / 429

Moving on to step 6:
429 goes into 1272 2 times with a remainder of 414.
Record the quotient 2 as the next digit in the result. 
Result so far: 1822.0
If we take 858 away from 1272, we end up with 414.
Fetch the next digit (1) from the dividend, attach it to 414 and continue: 4141 / 429

Advancing to step 7:
If we divide 4141 by 429, we get 9 and a remainder of 280.
Put 9 as the next digit of the answer. 
Result so far: 18229.0
Subtract 3861 from 4141 to get 280.
Append the next digit (0) from the dividend to 280 and continue with: 2800 / 429

Step 8:
2800 divided by 429 is 6 with a remainder of 226.
Write down 6 as next digit of the result. 
Result so far: 182296.0
Subtract 2574 from 2800 to get 226.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

Moving on to step 9:
When dividing 2260 by 429, we get 5 with a remainder of 115.
Put 5 as the next digit of the answer. 
Result so far: 182296.5
If we subtract 2145 from 2260, we get 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Let's proceed to step 10:
The number 429 fits into 1150 2 times, leaving a remainder of 292.
Use 2 as the next digit of our solution. 
Result so far: 182296.52
The remainder is 292 after subtracting 858 from 1150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

Let's proceed to step 11:
When dividing 2920 by 429, we get 6 with a remainder of 346.
The next digit of our result is 6. 
Result so far: 182296.526
Subtract 2574 from 2920 to get 346.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3460, and continue the process.

Step 12:
429 can be fit into 3460 8 times, resulting in a remainder of 28.
The number 8 becomes the next digit in our result. 
Result so far: 182296.5268
If we take 3432 away from 3460, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 13:
When dividing 280 by 429, we get 0 with a remainder of 280.
Write down 0 as next digit of the result. 
Result so far: 182296.5268
If we subtract 0 from 280, we get 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Let's proceed to step 14:
2800 divided by 429 is 6 with a remainder of 226.
Put 6 as the next digit of the answer. 
Result so far: 182296.526806
Deduct 2574 from 2800 and we're left with 226.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

Step 15:
429 can be fit into 2260 5 times, resulting in a remainder of 115.
The number 5 becomes the next digit in our result. 
Result so far: 182296.5268065
The remainder is 115 after subtracting 2145 from 2260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Advancing to step 16:
If we divide 1150 by 429, we get 2 and a remainder of 292.
The number 2 becomes the next digit in our result. 
Result so far: 182296.52680652
If we take 858 away from 1150, we end up with 292.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

The final outcome is 182296.52680652, with a leftover of 2.92e-07.
