We're dividing 86944494 by 7 
The aim is to understand the frequency of 7 in 86944494.

On to step 1:
7 can be fit into 8 1 times, resulting in a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 7 from 8 and we're left with 1.
Grab the next digit (6) from the dividend, add it to 1, then carry on: 16 / 7

Moving on to step 2:
When dividing 16 by 7, we get 2 with a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 12.0
If we take 14 away from 16, we end up with 2.
Grab the next digit (9) from the dividend, add it to 2, then carry on: 29 / 7

Going ahead to step 3:
The number 7 fits into 29 4 times, leaving a remainder of 1.
Record the quotient 4 as the next digit in the result. 
Result so far: 124.0
Subtract 28 from 29 to get 1.
Bring next digit (4) of the dividend behind the 1 and repeat the process: 14 / 7

Let's proceed to step 4:
7 can be fit into 14 2 times, resulting in a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 1242.0
Deduct 14 from 14 and we're left with 0.
Include the next digit (4) from the dividend after 0, then repeat: 4 / 7

Step 5:
7 goes into 4 0 times with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 12420.0
If we subtract 0 from 4, we get 4.
Take the next digit (4) from the dividend and append it to 4, then repeat: 44 / 7

Let's proceed to step 6:
7 can be fit into 44 6 times, resulting in a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 124206.0
Deduct 42 from 44 and we're left with 2.
Fetch the next digit (9) from the dividend, attach it to 2 and continue: 29 / 7

On to step 7:
When dividing 29 by 7, we get 4 with a remainder of 1.
The number 4 becomes the next digit in our result. 
Result so far: 1242064.0
If we take 28 away from 29, we end up with 1.
Fetch the next digit (4) from the dividend, attach it to 1 and continue: 14 / 7

On to step 8:
7 goes into 14 2 times with a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 12420642.0
If we subtract 14 from 14, 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.

Going ahead to step 9:
7 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 12420642.0
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.

Step 10:
7 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 12420642.0
Subtract 0 from 0 to 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.

The final outcome is 12420642.0, with a leftover of 0.0.
