Let's divide 764374 by 7
The aim is to understand the frequency of 7 in 764374.

Let's proceed to step 1:
The number 7 fits into 7 1 times, leaving a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 7 away from 7, we end up with 0.
Bring next digit (6) of the dividend behind the 0 and repeat the process: 6 / 7

Advancing to step 2:
If we divide 6 by 7, we get 0 and a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Subtracting 0 from 6 leaves us with 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 7

Advancing to step 3:
64 divided by 7 is 9 with a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 109.0
Deduct 63 from 64 and we're left with 1.
Append the next digit (3) from the dividend to 1 and continue with: 13 / 7

Moving on to step 4:
7 can be fit into 13 1 times, resulting in a remainder of 6.
The number 1 becomes the next digit in our result. 
Result so far: 1091.0
If we take 7 away from 13, we end up with 6.
Append the next digit (7) from the dividend to 6 and continue with: 67 / 7

Advancing to step 5:
67 divided by 7 is 9 with a remainder of 4.
The next digit of our result is 9. 
Result so far: 10919.0
If we subtract 63 from 67, we get 4.
Grab the next digit (4) from the dividend, add it to 4, then carry on: 44 / 7

On to step 6:
If we divide 44 by 7, we get 6 and a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 109196.0
Deduct 42 from 44 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 7:
If we divide 20 by 7, we get 2 and a remainder of 6.
The next digit of our result is 2. 
Result so far: 109196.2
The remainder is 6 after subtracting 14 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 8:
7 can be fit into 60 8 times, resulting in a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 109196.28
If we take 56 away from 60, we end up 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.

On to step 9:
When dividing 40 by 7, we get 5 with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 109196.285
Subtract 35 from 40 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 10:
7 goes into 50 7 times with a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 109196.2857
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 11:
When dividing 10 by 7, we get 1 with a remainder of 3.
The next digit of our result is 1. 
Result so far: 109196.28571
Subtract 7 from 10 to 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.

Moving on to step 12:
When dividing 30 by 7, we get 4 with a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 109196.285714
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.

Going ahead to step 13:
7 goes into 20 2 times with a remainder of 6.
The next digit of our result is 2. 
Result so far: 109196.2857142
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.

Advancing to step 14:
60 divided by 7 is 8 with a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 109196.28571428
If we subtract 56 from 60, we 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.

After the division, we end up with 109196.28571428 and a remainder of 4e-09.
