219686 divided by 7 
The aim is to understand the frequency of 7 in 219686.

Step 1:
The number 7 fits into 2 0 times, leaving a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 7

Step 2:
If we divide 21 by 7, we get 3 and a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtracting 21 from 21 leaves us with 0.
Grab the next digit (9) from the dividend, add it to 0, then carry on: 9 / 7

Let's proceed to step 3:
The number 7 fits into 9 1 times, leaving a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 31.0
Subtracting 7 from 9 leaves us with 2.
Append the next digit (6) from the dividend to 2 and continue with: 26 / 7

Going ahead to step 4:
26 divided by 7 is 3 with a remainder of 5.
Put 3 as the next digit of the answer. 
Result so far: 313.0
If we subtract 21 from 26, we get 5.
Grab the next digit (8) from the dividend, add it to 5, then carry on: 58 / 7

On to step 5:
58 divided by 7 is 8 with a remainder of 2.
Put 8 as the next digit of the answer. 
Result so far: 3138.0
The remainder is 2 after subtracting 56 from 58.
Bring next digit (6) of the dividend behind the 2 and repeat the process: 26 / 7

On to step 6:
When dividing 26 by 7, we get 3 with a remainder of 5.
Put 3 as the next digit of the answer. 
Result so far: 31383.0
If we take 21 away from 26, 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.

Going ahead to step 7:
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: 31383.7
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.

Advancing to step 8:
The number 7 fits into 10 1 times, leaving a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 31383.71
If we subtract 7 from 10, we get 3.
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 9:
When dividing 30 by 7, we get 4 with a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 31383.714
Subtract 28 from 30 to 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.

On to step 10:
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: 31383.7142
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 11:
The number 7 fits into 60 8 times, leaving a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 31383.71428
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.

Step 12:
If we divide 40 by 7, we get 5 and a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 31383.714285
Deduct 35 from 40 and we're left 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.

On to step 13:
50 divided by 7 is 7 with a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 31383.7142857
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.

Advancing to step 14:
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: 31383.71428571
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.

The final outcome is 31383.71428571, with a leftover of 3e-09.
