We look at the division of 809178 by 846 
The aim is to understand the frequency of 846 in 809178.

Advancing to step 1:
The number 846 fits into 8 0 times, leaving a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Append the next digit (0) from the dividend to 8 and continue with: 80 / 846

Advancing to step 2:
80 divided by 846 is 0 with a remainder of 80.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 80 leaves us with 80.
Take the next digit (9) from the dividend and append it to 80, then repeat: 809 / 846

On to step 3:
The number 846 fits into 809 0 times, leaving a remainder of 809.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 809 after subtracting 0 from 809.
Include the next digit (1) from the dividend after 809, then repeat: 8091 / 846

On to step 4:
8091 divided by 846 is 9 with a remainder of 477.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
If we take 7614 away from 8091, we end up with 477.
Bring next digit (7) of the dividend behind the 477 and repeat the process: 4777 / 846

On to step 5:
4777 divided by 846 is 5 with a remainder of 547.
Write down 5 as next digit of the result. 
Result so far: 95.0
If we subtract 4230 from 4777, we get 547.
Bring next digit (8) of the dividend behind the 547 and repeat the process: 5478 / 846

Let's proceed to step 6:
846 can be fit into 5478 6 times, resulting in a remainder of 402.
The next digit of our result is 6. 
Result so far: 956.0
Deduct 5076 from 5478 and we're left with 402.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4020, and continue the process.

Step 7:
The number 846 fits into 4020 4 times, leaving a remainder of 636.
Use 4 as the next digit of our solution. 
Result so far: 956.4
Subtract 3384 from 4020 to get 636.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6360, and continue the process.

Moving on to step 8:
846 can be fit into 6360 7 times, resulting in a remainder of 438.
Write down 7 as next digit of the result. 
Result so far: 956.47
If we subtract 5922 from 6360, we get 438.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4380, and continue the process.

Let's proceed to step 9:
4380 divided by 846 is 5 with a remainder of 150.
Write down 5 as next digit of the result. 
Result so far: 956.475
Subtract 4230 from 4380 to get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Step 10:
1500 divided by 846 is 1 with a remainder of 654.
Use 1 as the next digit of our solution. 
Result so far: 956.4751
The remainder is 654 after subtracting 846 from 1500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6540, and continue the process.

Moving on to step 11:
When dividing 6540 by 846, we get 7 with a remainder of 618.
Write down 7 as next digit of the result. 
Result so far: 956.47517
Subtracting 5922 from 6540 leaves us with 618.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6180, and continue the process.

Let's proceed to step 12:
846 goes into 6180 7 times with a remainder of 258.
Put 7 as the next digit of the answer. 
Result so far: 956.475177
Subtracting 5922 from 6180 leaves us with 258.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2580, and continue the process.

Our division results in 956.475177 with a remaining 2.58e-05.
