55467925 ÷ 391 
The aim is to understand the frequency of 391 in 55467925.

Let's proceed to step 1:
When dividing 5 by 391, we get 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Take the next digit (5) from the dividend and append it to 5, then repeat: 55 / 391

Step 2:
When dividing 55 by 391, we get 0 with a remainder of 55.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 55 and we're left with 55.
Grab the next digit (4) from the dividend, add it to 55, then carry on: 554 / 391

Moving on to step 3:
391 can be fit into 554 1 times, resulting in a remainder of 163.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 391 from 554 to get 163.
Bring next digit (6) of the dividend behind the 163 and repeat the process: 1636 / 391

Advancing to step 4:
If we divide 1636 by 391, we get 4 and a remainder of 72.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
If we subtract 1564 from 1636, we get 72.
Take the next digit (7) from the dividend and append it to 72, then repeat: 727 / 391

Step 5:
391 goes into 727 1 times with a remainder of 336.
The number 1 becomes the next digit in our result. 
Result so far: 141.0
The remainder is 336 after subtracting 391 from 727.
Fetch the next digit (9) from the dividend, attach it to 336 and continue: 3369 / 391

Step 6:
When dividing 3369 by 391, we get 8 with a remainder of 241.
Record the quotient 8 as the next digit in the result. 
Result so far: 1418.0
Deduct 3128 from 3369 and we're left with 241.
Bring next digit (2) of the dividend behind the 241 and repeat the process: 2412 / 391

Let's proceed to step 7:
The number 391 fits into 2412 6 times, leaving a remainder of 66.
The number 6 becomes the next digit in our result. 
Result so far: 14186.0
If we subtract 2346 from 2412, we get 66.
Fetch the next digit (5) from the dividend, attach it to 66 and continue: 665 / 391

On to step 8:
When dividing 665 by 391, we get 1 with a remainder of 274.
Put 1 as the next digit of the answer. 
Result so far: 141861.0
If we subtract 391 from 665, we get 274.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2740, and continue the process.

Going ahead to step 9:
The number 391 fits into 2740 7 times, leaving a remainder of 3.
Use 7 as the next digit of our solution. 
Result so far: 141861.7
Subtract 2737 from 2740 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 10:
The number 391 fits into 30 0 times, leaving a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 141861.7
Deduct 0 from 30 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 11:
391 can be fit into 300 0 times, resulting in a remainder of 300.
The number 0 becomes the next digit in our result. 
Result so far: 141861.7
The remainder is 300 after subtracting 0 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

The quotient of the division is 141861.7, and the remainder is 0.03.
