20018836 ÷ 349 
The aim is to understand the frequency of 349 in 20018836.

Let's proceed to step 1:
The number 349 fits into 2 0 times, leaving a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Bring next digit (0) of the dividend behind the 2 and repeat the process: 20 / 349

Going ahead to step 2:
If we divide 20 by 349, we get 0 and a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 20, we get 20.
Grab the next digit (0) from the dividend, add it to 20, then carry on: 200 / 349

Moving on to step 3:
200 divided by 349 is 0 with a remainder of 200.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 200, we get 200.
Grab the next digit (1) from the dividend, add it to 200, then carry on: 2001 / 349

Let's proceed to step 4:
349 goes into 2001 5 times with a remainder of 256.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
The remainder is 256 after subtracting 1745 from 2001.
Grab the next digit (8) from the dividend, add it to 256, then carry on: 2568 / 349

Step 5:
The number 349 fits into 2568 7 times, leaving a remainder of 125.
Put 7 as the next digit of the answer. 
Result so far: 57.0
Subtract 2443 from 2568 to get 125.
Bring next digit (8) of the dividend behind the 125 and repeat the process: 1258 / 349

Going ahead to step 6:
1258 divided by 349 is 3 with a remainder of 211.
Use 3 as the next digit of our solution. 
Result so far: 573.0
Subtract 1047 from 1258 to get 211.
Bring next digit (3) of the dividend behind the 211 and repeat the process: 2113 / 349

Advancing to step 7:
2113 divided by 349 is 6 with a remainder of 19.
The next digit of our result is 6. 
Result so far: 5736.0
The remainder is 19 after subtracting 2094 from 2113.
Grab the next digit (6) from the dividend, add it to 19, then carry on: 196 / 349

Moving on to step 8:
The number 349 fits into 196 0 times, leaving a remainder of 196.
Use 0 as the next digit of our solution. 
Result so far: 57360.0
If we take 0 away from 196, we end up with 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

Going ahead to step 9:
1960 divided by 349 is 5 with a remainder of 215.
Record the quotient 5 as the next digit in the result. 
Result so far: 57360.5
Subtract 1745 from 1960 to get 215.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2150, and continue the process.

Going ahead to step 10:
349 can be fit into 2150 6 times, resulting in a remainder of 56.
Use 6 as the next digit of our solution. 
Result so far: 57360.56
Deduct 2094 from 2150 and we're left with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

On to step 11:
560 divided by 349 is 1 with a remainder of 211.
The next digit of our result is 1. 
Result so far: 57360.561
The remainder is 211 after subtracting 349 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2110, and continue the process.

Moving on to step 12:
If we divide 2110 by 349, we get 6 and a remainder of 16.
Write down 6 as next digit of the result. 
Result so far: 57360.5616
Deduct 2094 from 2110 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 13:
160 divided by 349 is 0 with a remainder of 160.
Use 0 as the next digit of our solution. 
Result so far: 57360.5616
The remainder is 160 after subtracting 0 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

On to step 14:
349 can be fit into 1600 4 times, resulting in a remainder of 204.
Write down 4 as next digit of the result. 
Result so far: 57360.561604
Subtract 1396 from 1600 to get 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

Advancing to step 15:
349 can be fit into 2040 5 times, resulting in a remainder of 295.
Put 5 as the next digit of the answer. 
Result so far: 57360.5616045
Subtract 1745 from 2040 to get 295.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2950, and continue the process.

Advancing to step 16:
349 goes into 2950 8 times with a remainder of 158.
Use 8 as the next digit of our solution. 
Result so far: 57360.56160458
The remainder is 158 after subtracting 2792 from 2950.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

The final result is 57360.56160458 with a remainder of 1.58e-07.
