We divide 7957235 by 426
The aim is to understand the frequency of 426 in 7957235.

Step 1:
When dividing 7 by 426, we get 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Append the next digit (9) from the dividend to 7 and continue with: 79 / 426

On to step 2:
79 divided by 426 is 0 with a remainder of 79.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 79 after subtracting 0 from 79.
Take the next digit (5) from the dividend and append it to 79, then repeat: 795 / 426

Advancing to step 3:
426 goes into 795 1 times with a remainder of 369.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 426 from 795, we get 369.
Grab the next digit (7) from the dividend, add it to 369, then carry on: 3697 / 426

Advancing to step 4:
If we divide 3697 by 426, we get 8 and a remainder of 289.
The next digit of our result is 8. 
Result so far: 18.0
Deduct 3408 from 3697 and we're left with 289.
Append the next digit (2) from the dividend to 289 and continue with: 2892 / 426

Let's proceed to step 5:
2892 divided by 426 is 6 with a remainder of 336.
The next digit of our result is 6. 
Result so far: 186.0
The remainder is 336 after subtracting 2556 from 2892.
Bring next digit (3) of the dividend behind the 336 and repeat the process: 3363 / 426

Step 6:
If we divide 3363 by 426, we get 7 and a remainder of 381.
Put 7 as the next digit of the answer. 
Result so far: 1867.0
Deduct 2982 from 3363 and we're left with 381.
Grab the next digit (5) from the dividend, add it to 381, then carry on: 3815 / 426

Going ahead to step 7:
When dividing 3815 by 426, we get 8 with a remainder of 407.
The number 8 becomes the next digit in our result. 
Result so far: 18678.0
If we take 3408 away from 3815, we end up with 407.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4070, and continue the process.

On to step 8:
426 goes into 4070 9 times with a remainder of 236.
Use 9 as the next digit of our solution. 
Result so far: 18678.9
If we take 3834 away from 4070, we end up with 236.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

Going ahead to step 9:
426 can be fit into 2360 5 times, resulting in a remainder of 230.
Use 5 as the next digit of our solution. 
Result so far: 18678.95
Subtract 2130 from 2360 to get 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Moving on to step 10:
2300 divided by 426 is 5 with a remainder of 170.
The number 5 becomes the next digit in our result. 
Result so far: 18678.955
If we subtract 2130 from 2300, we get 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Our division results in 18678.955 with a remaining 0.017.
