We look at the division of 82986778 by 428 
The aim is to understand the frequency of 428 in 82986778.

Let's proceed to step 1:
8 divided by 428 is 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Grab the next digit (2) from the dividend, add it to 8, then carry on: 82 / 428

Advancing to step 2:
428 goes into 82 0 times with a remainder of 82.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 82 to get 82.
Take the next digit (9) from the dividend and append it to 82, then repeat: 829 / 428

Let's proceed to step 3:
428 can be fit into 829 1 times, resulting in a remainder of 401.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 428 from 829, we get 401.
Take the next digit (8) from the dividend and append it to 401, then repeat: 4018 / 428

Moving on to step 4:
4018 divided by 428 is 9 with a remainder of 166.
The next digit of our result is 9. 
Result so far: 19.0
Subtracting 3852 from 4018 leaves us with 166.
Take the next digit (6) from the dividend and append it to 166, then repeat: 1666 / 428

Moving on to step 5:
When dividing 1666 by 428, we get 3 with a remainder of 382.
Put 3 as the next digit of the answer. 
Result so far: 193.0
If we take 1284 away from 1666, we end up with 382.
Append the next digit (7) from the dividend to 382 and continue with: 3827 / 428

Advancing to step 6:
When dividing 3827 by 428, we get 8 with a remainder of 403.
Write down 8 as next digit of the result. 
Result so far: 1938.0
Subtracting 3424 from 3827 leaves us with 403.
Take the next digit (7) from the dividend and append it to 403, then repeat: 4037 / 428

On to step 7:
If we divide 4037 by 428, we get 9 and a remainder of 185.
The next digit of our result is 9. 
Result so far: 19389.0
Deduct 3852 from 4037 and we're left with 185.
Fetch the next digit (8) from the dividend, attach it to 185 and continue: 1858 / 428

Advancing to step 8:
If we divide 1858 by 428, we get 4 and a remainder of 146.
The next digit of our result is 4. 
Result so far: 193894.0
Subtracting 1712 from 1858 leaves us with 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

Step 9:
428 goes into 1460 3 times with a remainder of 176.
Write down 3 as next digit of the result. 
Result so far: 193894.3
Deduct 1284 from 1460 and we're left with 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Going ahead to step 10:
428 can be fit into 1760 4 times, resulting in a remainder of 48.
Use 4 as the next digit of our solution. 
Result so far: 193894.34
Subtracting 1712 from 1760 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 11:
When dividing 480 by 428, we get 1 with a remainder of 52.
Record the quotient 1 as the next digit in the result. 
Result so far: 193894.341
Subtracting 428 from 480 leaves us with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Let's proceed to step 12:
428 can be fit into 520 1 times, resulting in a remainder of 92.
Use 1 as the next digit of our solution. 
Result so far: 193894.3411
If we subtract 428 from 520, we get 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

The quotient of the division is 193894.3411, and the remainder is 0.00092.
