We look at the division of 31644493 by 347 
The aim is to understand the frequency of 347 in 31644493.

Let's proceed to step 1:
When dividing 3 by 347, we get 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Fetch the next digit (1) from the dividend, attach it to 3 and continue: 31 / 347

On to step 2:
The number 347 fits into 31 0 times, leaving a remainder of 31.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 31 leaves us with 31.
Fetch the next digit (6) from the dividend, attach it to 31 and continue: 316 / 347

Moving on to step 3:
347 can be fit into 316 0 times, resulting in a remainder of 316.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 316 and we're left with 316.
Fetch the next digit (4) from the dividend, attach it to 316 and continue: 3164 / 347

Advancing to step 4:
347 can be fit into 3164 9 times, resulting in a remainder of 41.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Subtract 3123 from 3164 to get 41.
Bring next digit (4) of the dividend behind the 41 and repeat the process: 414 / 347

Moving on to step 5:
If we divide 414 by 347, we get 1 and a remainder of 67.
Record the quotient 1 as the next digit in the result. 
Result so far: 91.0
Subtract 347 from 414 to get 67.
Append the next digit (4) from the dividend to 67 and continue with: 674 / 347

Step 6:
347 goes into 674 1 times with a remainder of 327.
Use 1 as the next digit of our solution. 
Result so far: 911.0
If we take 347 away from 674, we end up with 327.
Fetch the next digit (9) from the dividend, attach it to 327 and continue: 3279 / 347

On to step 7:
The number 347 fits into 3279 9 times, leaving a remainder of 156.
Record the quotient 9 as the next digit in the result. 
Result so far: 9119.0
Deduct 3123 from 3279 and we're left with 156.
Fetch the next digit (3) from the dividend, attach it to 156 and continue: 1563 / 347

Let's proceed to step 8:
347 goes into 1563 4 times with a remainder of 175.
Put 4 as the next digit of the answer. 
Result so far: 91194.0
If we take 1388 away from 1563, we end up with 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Let's proceed to step 9:
347 can be fit into 1750 5 times, resulting in a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 91194.5
If we take 1735 away from 1750, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 10:
The number 347 fits into 150 0 times, leaving a remainder of 150.
Use 0 as the next digit of our solution. 
Result so far: 91194.5
If we take 0 away from 150, we end up with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Let's proceed to step 11:
347 can be fit into 1500 4 times, resulting in a remainder of 112.
The number 4 becomes the next digit in our result. 
Result so far: 91194.504
The remainder is 112 after subtracting 1388 from 1500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Step 12:
347 goes into 1120 3 times with a remainder of 79.
Put 3 as the next digit of the answer. 
Result so far: 91194.5043
The remainder is 79 after subtracting 1041 from 1120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Let's proceed to step 13:
When dividing 790 by 347, we get 2 with a remainder of 96.
Write down 2 as next digit of the result. 
Result so far: 91194.50432
Subtract 694 from 790 to get 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Advancing to step 14:
When dividing 960 by 347, we get 2 with a remainder of 266.
Write down 2 as next digit of the result. 
Result so far: 91194.504322
Deduct 694 from 960 and we're left with 266.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2660, and continue the process.

After the division, we end up with 91194.504322 and a remainder of 2.66e-05.
