46398605 divided by 349 
The aim is to understand the frequency of 349 in 46398605.

Step 1:
4 divided by 349 is 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Include the next digit (6) from the dividend after 4, then repeat: 46 / 349

Going ahead to step 2:
If we divide 46 by 349, we get 0 and a remainder of 46.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 46, we get 46.
Include the next digit (3) from the dividend after 46, then repeat: 463 / 349

On to step 3:
When dividing 463 by 349, we get 1 with a remainder of 114.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 349 from 463 to get 114.
Grab the next digit (9) from the dividend, add it to 114, then carry on: 1149 / 349

Advancing to step 4:
1149 divided by 349 is 3 with a remainder of 102.
Use 3 as the next digit of our solution. 
Result so far: 13.0
If we take 1047 away from 1149, we end up with 102.
Grab the next digit (8) from the dividend, add it to 102, then carry on: 1028 / 349

Moving on to step 5:
When dividing 1028 by 349, we get 2 with a remainder of 330.
Record the quotient 2 as the next digit in the result. 
Result so far: 132.0
The remainder is 330 after subtracting 698 from 1028.
Include the next digit (6) from the dividend after 330, then repeat: 3306 / 349

Moving on to step 6:
The number 349 fits into 3306 9 times, leaving a remainder of 165.
Write down 9 as next digit of the result. 
Result so far: 1329.0
Subtract 3141 from 3306 to get 165.
Append the next digit (0) from the dividend to 165 and continue with: 1650 / 349

Let's proceed to step 7:
If we divide 1650 by 349, we get 4 and a remainder of 254.
Use 4 as the next digit of our solution. 
Result so far: 13294.0
Subtract 1396 from 1650 to get 254.
Include the next digit (5) from the dividend after 254, then repeat: 2545 / 349

Moving on to step 8:
If we divide 2545 by 349, we get 7 and a remainder of 102.
Use 7 as the next digit of our solution. 
Result so far: 132947.0
Deduct 2443 from 2545 and we're left with 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

On to step 9:
349 can be fit into 1020 2 times, resulting in a remainder of 322.
Put 2 as the next digit of the answer. 
Result so far: 132947.2
Subtract 698 from 1020 to get 322.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3220, and continue the process.

Moving on to step 10:
349 goes into 3220 9 times with a remainder of 79.
The next digit of our result is 9. 
Result so far: 132947.29
If we take 3141 away from 3220, we end up with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Going ahead to step 11:
790 divided by 349 is 2 with a remainder of 92.
The next digit of our result is 2. 
Result so far: 132947.292
If we take 698 away from 790, we end up with 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Step 12:
When dividing 920 by 349, we get 2 with a remainder of 222.
The next digit of our result is 2. 
Result so far: 132947.2922
Subtract 698 from 920 to get 222.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2220, and continue the process.

The final result is 132947.2922 with a remainder of 0.00222.
