We look at the division of 46485525 by 391 
The aim is to understand the frequency of 391 in 46485525.

Let's proceed to step 1:
391 goes into 4 0 times with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Take the next digit (6) from the dividend and append it to 4, then repeat: 46 / 391

Step 2:
391 can be fit into 46 0 times, resulting in a remainder of 46.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 46 after subtracting 0 from 46.
Include the next digit (4) from the dividend after 46, then repeat: 464 / 391

Moving on to step 3:
391 can be fit into 464 1 times, resulting in a remainder of 73.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 391 away from 464, we end up with 73.
Include the next digit (8) from the dividend after 73, then repeat: 738 / 391

Moving on to step 4:
When dividing 738 by 391, we get 1 with a remainder of 347.
Use 1 as the next digit of our solution. 
Result so far: 11.0
The remainder is 347 after subtracting 391 from 738.
Bring next digit (5) of the dividend behind the 347 and repeat the process: 3475 / 391

Step 5:
391 goes into 3475 8 times with a remainder of 347.
Write down 8 as next digit of the result. 
Result so far: 118.0
Deduct 3128 from 3475 and we're left with 347.
Take the next digit (5) from the dividend and append it to 347, then repeat: 3475 / 391

On to step 6:
391 can be fit into 3475 8 times, resulting in a remainder of 347.
Write down 8 as next digit of the result. 
Result so far: 1188.0
Subtracting 3128 from 3475 leaves us with 347.
Include the next digit (2) from the dividend after 347, then repeat: 3472 / 391

Step 7:
When dividing 3472 by 391, we get 8 with a remainder of 344.
Use 8 as the next digit of our solution. 
Result so far: 11888.0
Subtract 3128 from 3472 to get 344.
Fetch the next digit (5) from the dividend, attach it to 344 and continue: 3445 / 391

Step 8:
If we divide 3445 by 391, we get 8 and a remainder of 317.
Write down 8 as next digit of the result. 
Result so far: 118888.0
If we take 3128 away from 3445, we end up with 317.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3170, and continue the process.

Step 9:
When dividing 3170 by 391, we get 8 with a remainder of 42.
The next digit of our result is 8. 
Result so far: 118888.8
If we take 3128 away from 3170, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 10:
391 goes into 420 1 times with a remainder of 29.
The number 1 becomes the next digit in our result. 
Result so far: 118888.81
If we subtract 391 from 420, we get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Step 11:
391 goes into 290 0 times with a remainder of 290.
Record the quotient 0 as the next digit in the result. 
Result so far: 118888.81
The remainder is 290 after subtracting 0 from 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Going ahead to step 12:
2900 divided by 391 is 7 with a remainder of 163.
Use 7 as the next digit of our solution. 
Result so far: 118888.8107
The remainder is 163 after subtracting 2737 from 2900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1630, and continue the process.

Advancing to step 13:
391 can be fit into 1630 4 times, resulting in a remainder of 66.
The next digit of our result is 4. 
Result so far: 118888.81074
The remainder is 66 after subtracting 1564 from 1630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Going ahead to step 14:
If we divide 660 by 391, we get 1 and a remainder of 269.
Write down 1 as next digit of the result. 
Result so far: 118888.810741
Deduct 391 from 660 and we're left with 269.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2690, and continue the process.

Going ahead to step 15:
391 goes into 2690 6 times with a remainder of 344.
Record the quotient 6 as the next digit in the result. 
Result so far: 118888.8107416
Deduct 2346 from 2690 and we're left with 344.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

Going ahead to step 16:
When dividing 3440 by 391, we get 8 with a remainder of 312.
Record the quotient 8 as the next digit in the result. 
Result so far: 118888.81074168
Subtracting 3128 from 3440 leaves us with 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

Our division results in 118888.81074168 with a remaining 3.12e-07.
