Let's divide 31971 by 69
The aim is to understand the frequency of 69 in 31971.

Advancing to step 1:
When dividing 3 by 69, we get 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Grab the next digit (1) from the dividend, add it to 3, then carry on: 31 / 69

Moving on to step 2:
31 divided by 69 is 0 with a remainder of 31.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 31 to get 31.
Grab the next digit (9) from the dividend, add it to 31, then carry on: 319 / 69

Going ahead to step 3:
The number 69 fits into 319 4 times, leaving a remainder of 43.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Deduct 276 from 319 and we're left with 43.
Grab the next digit (7) from the dividend, add it to 43, then carry on: 437 / 69

Step 4:
69 can be fit into 437 6 times, resulting in a remainder of 23.
Put 6 as the next digit of the answer. 
Result so far: 46.0
If we subtract 414 from 437, we get 23.
Include the next digit (1) from the dividend after 23, then repeat: 231 / 69

Going ahead to step 5:
If we divide 231 by 69, we get 3 and a remainder of 24.
Put 3 as the next digit of the answer. 
Result so far: 463.0
Subtracting 207 from 231 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 6:
When dividing 240 by 69, we get 3 with a remainder of 33.
The number 3 becomes the next digit in our result. 
Result so far: 463.3
Deduct 207 from 240 and we're left with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Let's proceed to step 7:
330 divided by 69 is 4 with a remainder of 54.
Put 4 as the next digit of the answer. 
Result so far: 463.34
Deduct 276 from 330 and we're left with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Moving on to step 8:
When dividing 540 by 69, we get 7 with a remainder of 57.
Use 7 as the next digit of our solution. 
Result so far: 463.347
Subtract 483 from 540 to get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Moving on to step 9:
69 can be fit into 570 8 times, resulting in a remainder of 18.
Write down 8 as next digit of the result. 
Result so far: 463.3478
Subtract 552 from 570 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 10:
180 divided by 69 is 2 with a remainder of 42.
Put 2 as the next digit of the answer. 
Result so far: 463.34782
The remainder is 42 after subtracting 138 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 11:
69 goes into 420 6 times with a remainder of 6.
Use 6 as the next digit of our solution. 
Result so far: 463.347826
If we take 414 away from 420, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 12:
If we divide 60 by 69, we get 0 and a remainder of 60.
The next digit of our result is 0. 
Result so far: 463.347826
If we subtract 0 from 60, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 13:
When dividing 600 by 69, we get 8 with a remainder of 48.
Use 8 as the next digit of our solution. 
Result so far: 463.34782608
Subtract 552 from 600 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

The final result is 463.34782608 with a remainder of 4.8e-08.
