We divide 747871 by 7
The aim is to understand the frequency of 7 in 747871.

Moving on to step 1:
7 goes into 7 1 times with a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 7 from 7 to get 0.
Grab the next digit (4) from the dividend, add it to 0, then carry on: 4 / 7

Going ahead to step 2:
4 divided by 7 is 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Deduct 0 from 4 and we're left with 4.
Grab the next digit (7) from the dividend, add it to 4, then carry on: 47 / 7

Going ahead to step 3:
When dividing 47 by 7, we get 6 with a remainder of 5.
The next digit of our result is 6. 
Result so far: 106.0
If we take 42 away from 47, we end up with 5.
Include the next digit (8) from the dividend after 5, then repeat: 58 / 7

Advancing to step 4:
The number 7 fits into 58 8 times, leaving a remainder of 2.
Use 8 as the next digit of our solution. 
Result so far: 1068.0
If we subtract 56 from 58, we get 2.
Take the next digit (7) from the dividend and append it to 2, then repeat: 27 / 7

Advancing to step 5:
7 can be fit into 27 3 times, resulting in a remainder of 6.
Put 3 as the next digit of the answer. 
Result so far: 10683.0
If we take 21 away from 27, we end up with 6.
Bring next digit (1) of the dividend behind the 6 and repeat the process: 61 / 7

Advancing to step 6:
When dividing 61 by 7, we get 8 with a remainder of 5.
Put 8 as the next digit of the answer. 
Result so far: 106838.0
If we subtract 56 from 61, we 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.

Advancing to step 7:
The number 7 fits into 50 7 times, leaving a remainder of 1.
Use 7 as the next digit of our solution. 
Result so far: 106838.7
Subtract 49 from 50 to get 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:
If we divide 10 by 7, we get 1 and a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 106838.71
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.

On to step 9:
7 goes into 30 4 times with a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 106838.714
Subtracting 28 from 30 leaves us 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.

Advancing 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: 106838.7142
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.

Let's proceed to step 11:
When dividing 60 by 7, we get 8 with a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 106838.71428
The remainder is 4 after subtracting 56 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 12:
The number 7 fits into 40 5 times, leaving a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 106838.714285
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.

Going ahead to step 13:
If we divide 50 by 7, we get 7 and a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 106838.7142857
Subtract 49 from 50 to get 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:
When dividing 10 by 7, we get 1 with a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 106838.71428571
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.

The quotient of the division is 106838.71428571, and the remainder is 3e-09.
