373135 ÷ 7 
The aim is to understand the frequency of 7 in 373135.

Moving on to step 1:
7 can be fit into 3 0 times, resulting in a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Take the next digit (7) from the dividend and append it to 3, then repeat: 37 / 7

Going ahead to step 2:
7 goes into 37 5 times with a remainder of 2.
Write down 5 as next digit of the result. 
Result so far: 5.0
Deduct 35 from 37 and we're left with 2.
Append the next digit (3) from the dividend to 2 and continue with: 23 / 7

On to step 3:
23 divided by 7 is 3 with a remainder of 2.
Use 3 as the next digit of our solution. 
Result so far: 53.0
Subtract 21 from 23 to get 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 7

Moving on to step 4:
When dividing 21 by 7, we get 3 with a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 533.0
If we take 21 away from 21, we end up with 0.
Bring next digit (3) of the dividend behind the 0 and repeat the process: 3 / 7

Advancing to step 5:
If we divide 3 by 7, we get 0 and a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 5330.0
The remainder is 3 after subtracting 0 from 3.
Bring next digit (5) of the dividend behind the 3 and repeat the process: 35 / 7

Advancing to step 6:
7 goes into 35 5 times with a remainder of 0.
The next digit of our result is 5. 
Result so far: 53305.0
Deduct 35 from 35 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 7:
If we divide 0 by 7, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 53305.0
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 8:
If we divide 0 by 7, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 53305.0
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 53305.0 with a remaining 0.0.
