255160 divided by 7 
The aim is to understand the frequency of 7 in 255160.

On to step 1:
The number 7 fits into 2 0 times, leaving a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Append the next digit (5) from the dividend to 2 and continue with: 25 / 7

Advancing to step 2:
When dividing 25 by 7, we get 3 with a remainder of 4.
The next digit of our result is 3. 
Result so far: 3.0
Deduct 21 from 25 and we're left with 4.
Grab the next digit (5) from the dividend, add it to 4, then carry on: 45 / 7

Step 3:
If we divide 45 by 7, we get 6 and a remainder of 3.
The next digit of our result is 6. 
Result so far: 36.0
If we take 42 away from 45, we end up with 3.
Fetch the next digit (1) from the dividend, attach it to 3 and continue: 31 / 7

Let's proceed to step 4:
If we divide 31 by 7, we get 4 and a remainder of 3.
Use 4 as the next digit of our solution. 
Result so far: 364.0
Subtract 28 from 31 to get 3.
Include the next digit (6) from the dividend after 3, then repeat: 36 / 7

Advancing to step 5:
7 goes into 36 5 times with a remainder of 1.
The number 5 becomes the next digit in our result. 
Result so far: 3645.0
Subtracting 35 from 36 leaves us with 1.
Append the next digit (0) from the dividend to 1 and continue with: 10 / 7

Let's proceed to step 6:
7 can be fit into 10 1 times, resulting in a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 36451.0
If we take 7 away from 10, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 7:
When dividing 30 by 7, we get 4 with a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 36451.4
If we take 28 away from 30, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 8:
If we divide 20 by 7, we get 2 and a remainder of 6.
The number 2 becomes the next digit in our result. 
Result so far: 36451.42
Subtracting 14 from 20 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 9:
60 divided by 7 is 8 with a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 36451.428
If we take 56 away from 60, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 10:
The number 7 fits into 40 5 times, leaving a remainder of 5.
The next digit of our result is 5. 
Result so far: 36451.4285
Subtract 35 from 40 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 11:
50 divided by 7 is 7 with a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 36451.42857
Deduct 49 from 50 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 12:
7 goes into 10 1 times with a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 36451.428571
If we subtract 7 from 10, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 13:
7 goes into 30 4 times with a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 36451.4285714
Deduct 28 from 30 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 14:
20 divided by 7 is 2 with a remainder of 6.
Record the quotient 2 as the next digit in the result. 
Result so far: 36451.42857142
Subtracting 14 from 20 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

The quotient of the division is 36451.42857142, and the remainder is 6e-09.
