We divide 377958 by 7
The aim is to understand the frequency of 7 in 377958.

Moving on to step 1:
When dividing 3 by 7, we get 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Bring next digit (7) of the dividend behind the 3 and repeat the process: 37 / 7

Step 2:
The number 7 fits into 37 5 times, leaving a remainder of 2.
Put 5 as the next digit of the answer. 
Result so far: 5.0
The remainder is 2 after subtracting 35 from 37.
Include the next digit (7) from the dividend after 2, then repeat: 27 / 7

On to step 3:
If we divide 27 by 7, we get 3 and a remainder of 6.
The next digit of our result is 3. 
Result so far: 53.0
If we take 21 away from 27, we end up with 6.
Bring next digit (9) of the dividend behind the 6 and repeat the process: 69 / 7

Advancing to step 4:
When dividing 69 by 7, we get 9 with a remainder of 6.
Use 9 as the next digit of our solution. 
Result so far: 539.0
The remainder is 6 after subtracting 63 from 69.
Append the next digit (5) from the dividend to 6 and continue with: 65 / 7

On to step 5:
7 can be fit into 65 9 times, resulting in a remainder of 2.
Write down 9 as next digit of the result. 
Result so far: 5399.0
If we take 63 away from 65, we end up with 2.
Take the next digit (8) from the dividend and append it to 2, then repeat: 28 / 7

On to step 6:
7 can be fit into 28 4 times, resulting in a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 53994.0
If we subtract 28 from 28, 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.

On to step 7:
7 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 53994.0
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.

Let's proceed to step 8:
When dividing 0 by 7, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 53994.0
Deduct 0 from 0 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.

The final outcome is 53994.0, with a leftover of 0.0.
