65751621 ÷ 316 
The aim is to understand the frequency of 316 in 65751621.

Let's proceed to step 1:
If we divide 6 by 316, we get 0 and a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Bring next digit (5) of the dividend behind the 6 and repeat the process: 65 / 316

Step 2:
If we divide 65 by 316, we get 0 and a remainder of 65.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 65 and we're left with 65.
Bring next digit (7) of the dividend behind the 65 and repeat the process: 657 / 316

Moving on to step 3:
316 goes into 657 2 times with a remainder of 25.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 632 from 657 and we're left with 25.
Bring next digit (5) of the dividend behind the 25 and repeat the process: 255 / 316

Let's proceed to step 4:
316 can be fit into 255 0 times, resulting in a remainder of 255.
The next digit of our result is 0. 
Result so far: 20.0
If we take 0 away from 255, we end up with 255.
Append the next digit (1) from the dividend to 255 and continue with: 2551 / 316

On to step 5:
The number 316 fits into 2551 8 times, leaving a remainder of 23.
Write down 8 as next digit of the result. 
Result so far: 208.0
Deduct 2528 from 2551 and we're left with 23.
Append the next digit (6) from the dividend to 23 and continue with: 236 / 316

Advancing to step 6:
The number 316 fits into 236 0 times, leaving a remainder of 236.
Record the quotient 0 as the next digit in the result. 
Result so far: 2080.0
Deduct 0 from 236 and we're left with 236.
Fetch the next digit (2) from the dividend, attach it to 236 and continue: 2362 / 316

On to step 7:
2362 divided by 316 is 7 with a remainder of 150.
Write down 7 as next digit of the result. 
Result so far: 20807.0
If we take 2212 away from 2362, we end up with 150.
Bring next digit (1) of the dividend behind the 150 and repeat the process: 1501 / 316

Moving on to step 8:
If we divide 1501 by 316, we get 4 and a remainder of 237.
The number 4 becomes the next digit in our result. 
Result so far: 208074.0
If we take 1264 away from 1501, we end up with 237.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2370, and continue the process.

Advancing to step 9:
The number 316 fits into 2370 7 times, leaving a remainder of 158.
Record the quotient 7 as the next digit in the result. 
Result so far: 208074.7
If we subtract 2212 from 2370, we get 158.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

On to step 10:
316 goes into 1580 5 times with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 208074.75
If we subtract 1580 from 1580, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 11:
If we divide 0 by 316, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 208074.75
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 12:
If we divide 0 by 316, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 208074.75
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 208074.75 and a remainder of 0.0.
