We look at the division of 8679238 by 846 
The aim is to understand the frequency of 846 in 8679238.

Moving on to step 1:
If we divide 8 by 846, we get 0 and a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 846

Step 2:
846 can be fit into 86 0 times, resulting in a remainder of 86.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 86 leaves us with 86.
Bring next digit (7) of the dividend behind the 86 and repeat the process: 867 / 846

Let's proceed to step 3:
If we divide 867 by 846, we get 1 and a remainder of 21.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 846 from 867 and we're left with 21.
Fetch the next digit (9) from the dividend, attach it to 21 and continue: 219 / 846

Moving on to step 4:
If we divide 219 by 846, we get 0 and a remainder of 219.
Write down 0 as next digit of the result. 
Result so far: 10.0
If we subtract 0 from 219, we get 219.
Take the next digit (2) from the dividend and append it to 219, then repeat: 2192 / 846

On to step 5:
2192 divided by 846 is 2 with a remainder of 500.
Record the quotient 2 as the next digit in the result. 
Result so far: 102.0
Subtract 1692 from 2192 to get 500.
Fetch the next digit (3) from the dividend, attach it to 500 and continue: 5003 / 846

On to step 6:
The number 846 fits into 5003 5 times, leaving a remainder of 773.
The number 5 becomes the next digit in our result. 
Result so far: 1025.0
Subtracting 4230 from 5003 leaves us with 773.
Include the next digit (8) from the dividend after 773, then repeat: 7738 / 846

Advancing to step 7:
846 goes into 7738 9 times with a remainder of 124.
Record the quotient 9 as the next digit in the result. 
Result so far: 10259.0
If we take 7614 away from 7738, we end up with 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

Let's proceed to step 8:
If we divide 1240 by 846, we get 1 and a remainder of 394.
Record the quotient 1 as the next digit in the result. 
Result so far: 10259.1
Subtract 846 from 1240 to get 394.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3940, and continue the process.

On to step 9:
846 goes into 3940 4 times with a remainder of 556.
Record the quotient 4 as the next digit in the result. 
Result so far: 10259.14
Subtract 3384 from 3940 to get 556.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5560, and continue the process.

Step 10:
846 goes into 5560 6 times with a remainder of 484.
Use 6 as the next digit of our solution. 
Result so far: 10259.146
The remainder is 484 after subtracting 5076 from 5560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4840, and continue the process.

Advancing to step 11:
The number 846 fits into 4840 5 times, leaving a remainder of 610.
The next digit of our result is 5. 
Result so far: 10259.1465
Subtracting 4230 from 4840 leaves us with 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6100, and continue the process.

Step 12:
The number 846 fits into 6100 7 times, leaving a remainder of 178.
Record the quotient 7 as the next digit in the result. 
Result so far: 10259.14657
If we take 5922 away from 6100, we end up with 178.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1780, and continue the process.

Let's proceed to step 13:
846 goes into 1780 2 times with a remainder of 88.
The number 2 becomes the next digit in our result. 
Result so far: 10259.146572
If we subtract 1692 from 1780, we get 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Moving on to step 14:
846 goes into 880 1 times with a remainder of 34.
Put 1 as the next digit of the answer. 
Result so far: 10259.1465721
Deduct 846 from 880 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 15:
846 goes into 340 0 times with a remainder of 340.
Record the quotient 0 as the next digit in the result. 
Result so far: 10259.1465721
If we subtract 0 from 340, we get 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

The final result is 10259.1465721 with a remainder of 3.4e-07.
