We look at the division of 87647272 by 425 
The aim is to understand the frequency of 425 in 87647272.

Going ahead to step 1:
8 divided by 425 is 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Fetch the next digit (7) from the dividend, attach it to 8 and continue: 87 / 425

Going ahead to step 2:
87 divided by 425 is 0 with a remainder of 87.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 87 and we're left with 87.
Take the next digit (6) from the dividend and append it to 87, then repeat: 876 / 425

Step 3:
If we divide 876 by 425, we get 2 and a remainder of 26.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtracting 850 from 876 leaves us with 26.
Fetch the next digit (4) from the dividend, attach it to 26 and continue: 264 / 425

Advancing to step 4:
The number 425 fits into 264 0 times, leaving a remainder of 264.
Write down 0 as next digit of the result. 
Result so far: 20.0
Deduct 0 from 264 and we're left with 264.
Include the next digit (7) from the dividend after 264, then repeat: 2647 / 425

Going ahead to step 5:
The number 425 fits into 2647 6 times, leaving a remainder of 97.
The number 6 becomes the next digit in our result. 
Result so far: 206.0
The remainder is 97 after subtracting 2550 from 2647.
Grab the next digit (2) from the dividend, add it to 97, then carry on: 972 / 425

On to step 6:
When dividing 972 by 425, we get 2 with a remainder of 122.
Write down 2 as next digit of the result. 
Result so far: 2062.0
Subtract 850 from 972 to get 122.
Take the next digit (7) from the dividend and append it to 122, then repeat: 1227 / 425

Let's proceed to step 7:
If we divide 1227 by 425, we get 2 and a remainder of 377.
Use 2 as the next digit of our solution. 
Result so far: 20622.0
If we take 850 away from 1227, we end up with 377.
Include the next digit (2) from the dividend after 377, then repeat: 3772 / 425

On to step 8:
If we divide 3772 by 425, we get 8 and a remainder of 372.
The number 8 becomes the next digit in our result. 
Result so far: 206228.0
Deduct 3400 from 3772 and we're left with 372.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3720, and continue the process.

Moving on to step 9:
If we divide 3720 by 425, we get 8 and a remainder of 320.
Record the quotient 8 as the next digit in the result. 
Result so far: 206228.8
Subtracting 3400 from 3720 leaves us with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Going ahead to step 10:
When dividing 3200 by 425, we get 7 with a remainder of 225.
Put 7 as the next digit of the answer. 
Result so far: 206228.87
Deduct 2975 from 3200 and we're left 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.

Step 11:
425 can be fit into 2250 5 times, resulting in a remainder of 125.
Put 5 as the next digit of the answer. 
Result so far: 206228.875
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.

Advancing to step 12:
When dividing 1250 by 425, we get 2 with a remainder of 400.
Put 2 as the next digit of the answer. 
Result so far: 206228.8752
If we take 850 away from 1250, we end up with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Advancing to step 13:
425 goes into 4000 9 times with a remainder of 175.
Write down 9 as next digit of the result. 
Result so far: 206228.87529
The remainder is 175 after subtracting 3825 from 4000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Step 14:
If we divide 1750 by 425, we get 4 and a remainder of 50.
Write down 4 as next digit of the result. 
Result so far: 206228.875294
Deduct 1700 from 1750 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 15:
The number 425 fits into 500 1 times, leaving a remainder of 75.
Record the quotient 1 as the next digit in the result. 
Result so far: 206228.8752941
Deduct 425 from 500 and we're left with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Let's proceed to step 16:
If we divide 750 by 425, we get 1 and a remainder of 325.
The number 1 becomes the next digit in our result. 
Result so far: 206228.87529411
Deduct 425 from 750 and we're left with 325.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3250, and continue the process.

After the division, we end up with 206228.87529411 and a remainder of 3.25e-07.
