We look at the division of 88970250 by 426 
The aim is to understand the frequency of 426 in 88970250.

On to step 1:
If we divide 8 by 426, we get 0 and a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Include the next digit (8) from the dividend after 8, then repeat: 88 / 426

On to step 2:
426 goes into 88 0 times with a remainder of 88.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 88 after subtracting 0 from 88.
Include the next digit (9) from the dividend after 88, then repeat: 889 / 426

On to step 3:
The number 426 fits into 889 2 times, leaving a remainder of 37.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we subtract 852 from 889, we get 37.
Fetch the next digit (7) from the dividend, attach it to 37 and continue: 377 / 426

On to step 4:
When dividing 377 by 426, we get 0 with a remainder of 377.
Use 0 as the next digit of our solution. 
Result so far: 20.0
If we take 0 away from 377, we end up with 377.
Take the next digit (0) from the dividend and append it to 377, then repeat: 3770 / 426

Moving on to step 5:
426 goes into 3770 8 times with a remainder of 362.
Write down 8 as next digit of the result. 
Result so far: 208.0
Subtract 3408 from 3770 to get 362.
Fetch the next digit (2) from the dividend, attach it to 362 and continue: 3622 / 426

Let's proceed to step 6:
When dividing 3622 by 426, we get 8 with a remainder of 214.
Put 8 as the next digit of the answer. 
Result so far: 2088.0
If we take 3408 away from 3622, we end up with 214.
Grab the next digit (5) from the dividend, add it to 214, then carry on: 2145 / 426

Step 7:
426 goes into 2145 5 times with a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 20885.0
Subtracting 2130 from 2145 leaves us with 15.
Take the next digit (0) from the dividend and append it to 15, then repeat: 150 / 426

Going ahead to step 8:
The number 426 fits into 150 0 times, leaving a remainder of 150.
The next digit of our result is 0. 
Result so far: 208850.0
Deduct 0 from 150 and we're left with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Let's proceed to step 9:
When dividing 1500 by 426, we get 3 with a remainder of 222.
The next digit of our result is 3. 
Result so far: 208850.3
If we subtract 1278 from 1500, we get 222.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2220, and continue the process.

Going ahead to step 10:
426 can be fit into 2220 5 times, resulting in a remainder of 90.
Write down 5 as next digit of the result. 
Result so far: 208850.35
Subtract 2130 from 2220 to get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Going ahead to step 11:
900 divided by 426 is 2 with a remainder of 48.
Put 2 as the next digit of the answer. 
Result so far: 208850.352
If we take 852 away from 900, we end up 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.

On to step 12:
When dividing 480 by 426, we get 1 with a remainder of 54.
Record the quotient 1 as the next digit in the result. 
Result so far: 208850.3521
Subtract 426 from 480 to get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

On to step 13:
426 goes into 540 1 times with a remainder of 114.
Record the quotient 1 as the next digit in the result. 
Result so far: 208850.35211
If we take 426 away from 540, we end up with 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

The final result is 208850.35211 with a remainder of 0.000114.
