90791368 divided by 425 
The aim is to understand the frequency of 425 in 90791368.

On to step 1:
The number 425 fits into 9 0 times, leaving a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Fetch the next digit (0) from the dividend, attach it to 9 and continue: 90 / 425

Moving on to step 2:
425 goes into 90 0 times with a remainder of 90.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 90, we end up with 90.
Take the next digit (7) from the dividend and append it to 90, then repeat: 907 / 425

Going ahead to step 3:
The number 425 fits into 907 2 times, leaving a remainder of 57.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we take 850 away from 907, we end up with 57.
Include the next digit (9) from the dividend after 57, then repeat: 579 / 425

Going ahead to step 4:
579 divided by 425 is 1 with a remainder of 154.
Record the quotient 1 as the next digit in the result. 
Result so far: 21.0
If we take 425 away from 579, we end up with 154.
Fetch the next digit (1) from the dividend, attach it to 154 and continue: 1541 / 425

On to step 5:
425 can be fit into 1541 3 times, resulting in a remainder of 266.
Put 3 as the next digit of the answer. 
Result so far: 213.0
If we subtract 1275 from 1541, we get 266.
Append the next digit (3) from the dividend to 266 and continue with: 2663 / 425

Going ahead to step 6:
When dividing 2663 by 425, we get 6 with a remainder of 113.
Write down 6 as next digit of the result. 
Result so far: 2136.0
Subtracting 2550 from 2663 leaves us with 113.
Bring next digit (6) of the dividend behind the 113 and repeat the process: 1136 / 425

Moving on to step 7:
1136 divided by 425 is 2 with a remainder of 286.
Record the quotient 2 as the next digit in the result. 
Result so far: 21362.0
The remainder is 286 after subtracting 850 from 1136.
Include the next digit (8) from the dividend after 286, then repeat: 2868 / 425

Going ahead to step 8:
When dividing 2868 by 425, we get 6 with a remainder of 318.
Write down 6 as next digit of the result. 
Result so far: 213626.0
The remainder is 318 after subtracting 2550 from 2868.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3180, and continue the process.

On to step 9:
425 goes into 3180 7 times with a remainder of 205.
Put 7 as the next digit of the answer. 
Result so far: 213626.7
Subtracting 2975 from 3180 leaves us with 205.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

Going ahead to step 10:
425 goes into 2050 4 times with a remainder of 350.
Record the quotient 4 as the next digit in the result. 
Result so far: 213626.74
If we take 1700 away from 2050, we end up with 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Moving on to step 11:
The number 425 fits into 3500 8 times, leaving a remainder of 100.
Use 8 as the next digit of our solution. 
Result so far: 213626.748
Subtracting 3400 from 3500 leaves us with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

On to step 12:
If we divide 1000 by 425, we get 2 and a remainder of 150.
The next digit of our result is 2. 
Result so far: 213626.7482
If we subtract 850 from 1000, we get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Step 13:
When dividing 1500 by 425, we get 3 with a remainder of 225.
Write down 3 as next digit of the result. 
Result so far: 213626.74823
Subtracting 1275 from 1500 leaves us with 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

Advancing to step 14:
When dividing 2250 by 425, we get 5 with a remainder of 125.
Record the quotient 5 as the next digit in the result. 
Result so far: 213626.748235
Subtract 2125 from 2250 to get 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

On to step 15:
If we divide 1250 by 425, we get 2 and a remainder of 400.
The next digit of our result is 2. 
Result so far: 213626.7482352
Subtract 850 from 1250 to get 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

On to step 16:
When dividing 4000 by 425, we get 9 with a remainder of 175.
The next digit of our result is 9. 
Result so far: 213626.74823529
If we take 3825 away from 4000, we end up with 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

The final outcome is 213626.74823529, with a leftover of 1.75e-07.
