We're dividing 590941 by 7 
The aim is to understand the frequency of 7 in 590941.

Advancing to step 1:
7 can be fit into 5 0 times, resulting in a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Include the next digit (9) from the dividend after 5, then repeat: 59 / 7

Step 2:
7 can be fit into 59 8 times, resulting in a remainder of 3.
Put 8 as the next digit of the answer. 
Result so far: 8.0
If we subtract 56 from 59, we get 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 7

Moving on to step 3:
If we divide 30 by 7, we get 4 and a remainder of 2.
The next digit of our result is 4. 
Result so far: 84.0
The remainder is 2 after subtracting 28 from 30.
Take the next digit (9) from the dividend and append it to 2, then repeat: 29 / 7

Step 4:
7 can be fit into 29 4 times, resulting in a remainder of 1.
The next digit of our result is 4. 
Result so far: 844.0
Deduct 28 from 29 and we're left with 1.
Include the next digit (4) from the dividend after 1, then repeat: 14 / 7

On to step 5:
7 can be fit into 14 2 times, resulting in a remainder of 0.
The next digit of our result is 2. 
Result so far: 8442.0
Subtract 14 from 14 to get 0.
Grab the next digit (1) from the dividend, add it to 0, then carry on: 1 / 7

On to step 6:
1 divided by 7 is 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 84420.0
Deduct 0 from 1 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 7:
If we divide 10 by 7, we get 1 and a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 84420.1
Deduct 7 from 10 and we're left 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.

On to step 8:
When dividing 30 by 7, we get 4 with a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 84420.14
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.

Let's proceed to step 9:
7 can be fit into 20 2 times, resulting in a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 84420.142
If we take 14 away from 20, we end up 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 10:
60 divided by 7 is 8 with a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 84420.1428
Subtracting 56 from 60 leaves us 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.

Let's proceed to step 11:
7 goes into 40 5 times with a remainder of 5.
The next digit of our result is 5. 
Result so far: 84420.14285
The remainder is 5 after subtracting 35 from 40.
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 12:
The number 7 fits into 50 7 times, leaving a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 84420.142857
The remainder is 1 after subtracting 49 from 50.
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 13:
When dividing 10 by 7, we get 1 with a remainder of 3.
The next digit of our result is 1. 
Result so far: 84420.1428571
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.

Let's proceed to step 14:
7 goes into 30 4 times with a remainder of 2.
The next digit of our result is 4. 
Result so far: 84420.14285714
If we subtract 28 from 30, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

The final outcome is 84420.14285714, with a leftover of 2e-09.
