We're dividing 46737739 by 391 
The aim is to understand the frequency of 391 in 46737739.

Let's proceed to step 1:
The number 391 fits into 4 0 times, leaving a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Take the next digit (6) from the dividend and append it to 4, then repeat: 46 / 391

Advancing to step 2:
391 goes into 46 0 times with a remainder of 46.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 46, we end up with 46.
Fetch the next digit (7) from the dividend, attach it to 46 and continue: 467 / 391

Let's proceed to step 3:
The number 391 fits into 467 1 times, leaving a remainder of 76.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 391 away from 467, we end up with 76.
Take the next digit (3) from the dividend and append it to 76, then repeat: 763 / 391

Let's proceed to step 4:
When dividing 763 by 391, we get 1 with a remainder of 372.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
Deduct 391 from 763 and we're left with 372.
Append the next digit (7) from the dividend to 372 and continue with: 3727 / 391

On to step 5:
391 can be fit into 3727 9 times, resulting in a remainder of 208.
Record the quotient 9 as the next digit in the result. 
Result so far: 119.0
Deduct 3519 from 3727 and we're left with 208.
Fetch the next digit (7) from the dividend, attach it to 208 and continue: 2087 / 391

Step 6:
391 goes into 2087 5 times with a remainder of 132.
Put 5 as the next digit of the answer. 
Result so far: 1195.0
Subtracting 1955 from 2087 leaves us with 132.
Include the next digit (3) from the dividend after 132, then repeat: 1323 / 391

Moving on to step 7:
The number 391 fits into 1323 3 times, leaving a remainder of 150.
Write down 3 as next digit of the result. 
Result so far: 11953.0
If we take 1173 away from 1323, we end up with 150.
Fetch the next digit (9) from the dividend, attach it to 150 and continue: 1509 / 391

Advancing to step 8:
1509 divided by 391 is 3 with a remainder of 336.
Record the quotient 3 as the next digit in the result. 
Result so far: 119533.0
If we take 1173 away from 1509, we end up with 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

Step 9:
3360 divided by 391 is 8 with a remainder of 232.
Use 8 as the next digit of our solution. 
Result so far: 119533.8
Deduct 3128 from 3360 and we're left with 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Step 10:
When dividing 2320 by 391, we get 5 with a remainder of 365.
Record the quotient 5 as the next digit in the result. 
Result so far: 119533.85
The remainder is 365 after subtracting 1955 from 2320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3650, and continue the process.

Advancing to step 11:
3650 divided by 391 is 9 with a remainder of 131.
The next digit of our result is 9. 
Result so far: 119533.859
The remainder is 131 after subtracting 3519 from 3650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1310, and continue the process.

Advancing to step 12:
391 can be fit into 1310 3 times, resulting in a remainder of 137.
The next digit of our result is 3. 
Result so far: 119533.8593
Subtracting 1173 from 1310 leaves us with 137.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1370, and continue the process.

On to step 13:
391 goes into 1370 3 times with a remainder of 197.
Write down 3 as next digit of the result. 
Result so far: 119533.85933
Subtracting 1173 from 1370 leaves us with 197.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1970, and continue the process.

The final outcome is 119533.85933, with a leftover of 0.000197.
