We divide 10173537 by 7
The aim is to understand the frequency of 7 in 10173537.

Going ahead to step 1:
If we divide 1 by 7, we get 0 and a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Bring next digit (0) of the dividend behind the 1 and repeat the process: 10 / 7

Going ahead to step 2:
If we divide 10 by 7, we get 1 and a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 7 from 10, we get 3.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 7

On to step 3:
31 divided by 7 is 4 with a remainder of 3.
Use 4 as the next digit of our solution. 
Result so far: 14.0
The remainder is 3 after subtracting 28 from 31.
Append the next digit (7) from the dividend to 3 and continue with: 37 / 7

Going ahead to step 4:
If we divide 37 by 7, we get 5 and a remainder of 2.
The number 5 becomes the next digit in our result. 
Result so far: 145.0
Subtract 35 from 37 to get 2.
Take the next digit (3) from the dividend and append it to 2, then repeat: 23 / 7

On to step 5:
When dividing 23 by 7, we get 3 with a remainder of 2.
Write down 3 as next digit of the result. 
Result so far: 1453.0
Subtract 21 from 23 to get 2.
Include the next digit (5) from the dividend after 2, then repeat: 25 / 7

On to step 6:
25 divided by 7 is 3 with a remainder of 4.
The next digit of our result is 3. 
Result so far: 14533.0
If we subtract 21 from 25, we get 4.
Bring next digit (3) of the dividend behind the 4 and repeat the process: 43 / 7

Going ahead to step 7:
43 divided by 7 is 6 with a remainder of 1.
Use 6 as the next digit of our solution. 
Result so far: 145336.0
If we subtract 42 from 43, we get 1.
Include the next digit (7) from the dividend after 1, then repeat: 17 / 7

Moving on to step 8:
If we divide 17 by 7, we get 2 and a remainder of 3.
Put 2 as the next digit of the answer. 
Result so far: 1453362.0
Subtracting 14 from 17 leaves us 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.

Moving on to step 9:
7 goes into 30 4 times with a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 1453362.4
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.

Moving on to step 10:
The number 7 fits into 20 2 times, leaving a remainder of 6.
Record the quotient 2 as the next digit in the result. 
Result so far: 1453362.42
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.

Going ahead to step 11:
60 divided by 7 is 8 with a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 1453362.428
Subtract 56 from 60 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 12:
40 divided by 7 is 5 with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 1453362.4285
If we take 35 away from 40, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 13:
The number 7 fits into 50 7 times, leaving a remainder of 1.
Write down 7 as next digit of the result. 
Result so far: 1453362.42857
Subtracting 49 from 50 leaves us 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.

Let's proceed to step 14:
7 can be fit into 10 1 times, resulting in a remainder of 3.
The next digit of our result is 1. 
Result so far: 1453362.428571
The remainder is 3 after subtracting 7 from 10.
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 15:
7 goes into 30 4 times with a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 1453362.4285714
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 16:
When dividing 20 by 7, we get 2 with a remainder of 6.
The number 2 becomes the next digit in our result. 
Result so far: 1453362.42857142
If we subtract 14 from 20, we get 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 final outcome is 1453362.42857142, with a leftover of 6e-09.
