29847915 divided by 425 
The aim is to understand the frequency of 425 in 29847915.

Step 1:
2 divided by 425 is 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Include the next digit (9) from the dividend after 2, then repeat: 29 / 425

On to step 2:
If we divide 29 by 425, we get 0 and a remainder of 29.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 29 leaves us with 29.
Grab the next digit (8) from the dividend, add it to 29, then carry on: 298 / 425

Let's proceed to step 3:
The number 425 fits into 298 0 times, leaving a remainder of 298.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 298 and we're left with 298.
Fetch the next digit (4) from the dividend, attach it to 298 and continue: 2984 / 425

Moving on to step 4:
2984 divided by 425 is 7 with a remainder of 9.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Deduct 2975 from 2984 and we're left with 9.
Fetch the next digit (7) from the dividend, attach it to 9 and continue: 97 / 425

Advancing to step 5:
425 can be fit into 97 0 times, resulting in a remainder of 97.
Put 0 as the next digit of the answer. 
Result so far: 70.0
Deduct 0 from 97 and we're left with 97.
Grab the next digit (9) from the dividend, add it to 97, then carry on: 979 / 425

Advancing to step 6:
425 goes into 979 2 times with a remainder of 129.
Put 2 as the next digit of the answer. 
Result so far: 702.0
Deduct 850 from 979 and we're left with 129.
Fetch the next digit (1) from the dividend, attach it to 129 and continue: 1291 / 425

Let's proceed to step 7:
If we divide 1291 by 425, we get 3 and a remainder of 16.
Write down 3 as next digit of the result. 
Result so far: 7023.0
If we subtract 1275 from 1291, we get 16.
Fetch the next digit (5) from the dividend, attach it to 16 and continue: 165 / 425

Step 8:
If we divide 165 by 425, we get 0 and a remainder of 165.
Put 0 as the next digit of the answer. 
Result so far: 70230.0
Deduct 0 from 165 and we're left with 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

Going ahead to step 9:
425 can be fit into 1650 3 times, resulting in a remainder of 375.
Write down 3 as next digit of the result. 
Result so far: 70230.3
If we subtract 1275 from 1650, we get 375.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3750, and continue the process.

On to step 10:
If we divide 3750 by 425, we get 8 and a remainder of 350.
The number 8 becomes the next digit in our result. 
Result so far: 70230.38
If we subtract 3400 from 3750, we get 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Step 11:
When dividing 3500 by 425, we get 8 with a remainder of 100.
Record the quotient 8 as the next digit in the result. 
Result so far: 70230.388
Deduct 3400 from 3500 and we're left 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.

The final outcome is 70230.388, with a leftover of 0.01.
