We look at the division of 7905847 by 426 
The aim is to understand the frequency of 426 in 7905847.

Going ahead to step 1:
7 divided by 426 is 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Take the next digit (9) from the dividend and append it to 7, then repeat: 79 / 426

Moving on to step 2:
If we divide 79 by 426, we get 0 and a remainder of 79.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 79, we get 79.
Include the next digit (0) from the dividend after 79, then repeat: 790 / 426

On to step 3:
426 goes into 790 1 times with a remainder of 364.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 364 after subtracting 426 from 790.
Include the next digit (5) from the dividend after 364, then repeat: 3645 / 426

Going ahead to step 4:
426 goes into 3645 8 times with a remainder of 237.
The next digit of our result is 8. 
Result so far: 18.0
Subtract 3408 from 3645 to get 237.
Include the next digit (8) from the dividend after 237, then repeat: 2378 / 426

On to step 5:
426 can be fit into 2378 5 times, resulting in a remainder of 248.
Put 5 as the next digit of the answer. 
Result so far: 185.0
Deduct 2130 from 2378 and we're left with 248.
Fetch the next digit (4) from the dividend, attach it to 248 and continue: 2484 / 426

Going ahead to step 6:
The number 426 fits into 2484 5 times, leaving a remainder of 354.
Write down 5 as next digit of the result. 
Result so far: 1855.0
If we subtract 2130 from 2484, we get 354.
Append the next digit (7) from the dividend to 354 and continue with: 3547 / 426

Advancing to step 7:
3547 divided by 426 is 8 with a remainder of 139.
The next digit of our result is 8. 
Result so far: 18558.0
The remainder is 139 after subtracting 3408 from 3547.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1390, and continue the process.

Step 8:
The number 426 fits into 1390 3 times, leaving a remainder of 112.
Record the quotient 3 as the next digit in the result. 
Result so far: 18558.3
The remainder is 112 after subtracting 1278 from 1390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Advancing to step 9:
The number 426 fits into 1120 2 times, leaving a remainder of 268.
Write down 2 as next digit of the result. 
Result so far: 18558.32
Subtracting 852 from 1120 leaves us with 268.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

On to step 10:
If we divide 2680 by 426, we get 6 and a remainder of 124.
The next digit of our result is 6. 
Result so far: 18558.326
If we subtract 2556 from 2680, we get 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

Let's proceed to step 11:
When dividing 1240 by 426, we get 2 with a remainder of 388.
Record the quotient 2 as the next digit in the result. 
Result so far: 18558.3262
The remainder is 388 after subtracting 852 from 1240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3880, and continue the process.

Let's proceed to step 12:
3880 divided by 426 is 9 with a remainder of 46.
The next digit of our result is 9. 
Result so far: 18558.32629
Deduct 3834 from 3880 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Going ahead to step 13:
If we divide 460 by 426, we get 1 and a remainder of 34.
Record the quotient 1 as the next digit in the result. 
Result so far: 18558.326291
Deduct 426 from 460 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 14:
When dividing 340 by 426, we get 0 with a remainder of 340.
Put 0 as the next digit of the answer. 
Result so far: 18558.326291
Subtract 0 from 340 to get 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Let's proceed to step 15:
When dividing 3400 by 426, we get 7 with a remainder of 418.
Record the quotient 7 as the next digit in the result. 
Result so far: 18558.32629107
Deduct 2982 from 3400 and we're left with 418.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4180, and continue the process.

The final outcome is 18558.32629107, with a leftover of 4.18e-07.
