908546 divided by 7 
The aim is to understand the frequency of 7 in 908546.

Going ahead to step 1:
If we divide 9 by 7, we get 1 and a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 2 after subtracting 7 from 9.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 7

Advancing to step 2:
When dividing 20 by 7, we get 2 with a remainder of 6.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
If we subtract 14 from 20, we get 6.
Bring next digit (8) of the dividend behind the 6 and repeat the process: 68 / 7

On to step 3:
If we divide 68 by 7, we get 9 and a remainder of 5.
Use 9 as the next digit of our solution. 
Result so far: 129.0
Subtracting 63 from 68 leaves us with 5.
Grab the next digit (5) from the dividend, add it to 5, then carry on: 55 / 7

On to step 4:
7 goes into 55 7 times with a remainder of 6.
The number 7 becomes the next digit in our result. 
Result so far: 1297.0
Subtracting 49 from 55 leaves us with 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 7

On to step 5:
7 can be fit into 64 9 times, resulting in a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 12979.0
Deduct 63 from 64 and we're left with 1.
Take the next digit (6) from the dividend and append it to 1, then repeat: 16 / 7

Going ahead to step 6:
7 can be fit into 16 2 times, resulting in a remainder of 2.
The next digit of our result is 2. 
Result so far: 129792.0
Deduct 14 from 16 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.

Moving on to step 7:
The number 7 fits into 20 2 times, leaving a remainder of 6.
The number 2 becomes the next digit in our result. 
Result so far: 129792.2
Deduct 14 from 20 and we're left 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.

On to step 8:
60 divided by 7 is 8 with a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 129792.28
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.

Going ahead to step 9:
40 divided by 7 is 5 with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 129792.285
If we take 35 away from 40, 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.

On to step 10:
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: 129792.2857
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.

Step 11:
When dividing 10 by 7, we get 1 with a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 129792.28571
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.

Step 12:
7 goes into 30 4 times with a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 129792.285714
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.

Moving on to step 13:
7 can be fit into 20 2 times, resulting in a remainder of 6.
The number 2 becomes the next digit in our result. 
Result so far: 129792.2857142
Subtract 14 from 20 to get 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:
7 can be fit into 60 8 times, resulting in a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 129792.28571428
Subtract 56 from 60 to 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 129792.28571428 and a remainder of 4e-09.
