We look at the division of 20786658 by 349 
The aim is to understand the frequency of 349 in 20786658.

Moving on to step 1:
349 can be fit into 2 0 times, resulting in a remainder of 2.
Use 0 as the next digit of our solution. 
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

Let's proceed to step 2:
20 divided by 349 is 0 with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 20, we get 20.
Grab the next digit (7) from the dividend, add it to 20, then carry on: 207 / 349

Let's proceed to step 3:
349 goes into 207 0 times with a remainder of 207.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 207, we get 207.
Grab the next digit (8) from the dividend, add it to 207, then carry on: 2078 / 349

Advancing to step 4:
2078 divided by 349 is 5 with a remainder of 333.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Subtracting 1745 from 2078 leaves us with 333.
Grab the next digit (6) from the dividend, add it to 333, then carry on: 3336 / 349

Let's proceed to step 5:
349 goes into 3336 9 times with a remainder of 195.
Write down 9 as next digit of the result. 
Result so far: 59.0
Deduct 3141 from 3336 and we're left with 195.
Append the next digit (6) from the dividend to 195 and continue with: 1956 / 349

Let's proceed to step 6:
1956 divided by 349 is 5 with a remainder of 211.
Write down 5 as next digit of the result. 
Result so far: 595.0
If we subtract 1745 from 1956, we get 211.
Take the next digit (5) from the dividend and append it to 211, then repeat: 2115 / 349

Step 7:
If we divide 2115 by 349, we get 6 and a remainder of 21.
Use 6 as the next digit of our solution. 
Result so far: 5956.0
If we subtract 2094 from 2115, we get 21.
Include the next digit (8) from the dividend after 21, then repeat: 218 / 349

Step 8:
349 can be fit into 218 0 times, resulting in a remainder of 218.
Put 0 as the next digit of the answer. 
Result so far: 59560.0
If we take 0 away from 218, we end up with 218.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

Let's proceed to step 9:
349 goes into 2180 6 times with a remainder of 86.
Put 6 as the next digit of the answer. 
Result so far: 59560.6
If we take 2094 away from 2180, we end up with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Step 10:
When dividing 860 by 349, we get 2 with a remainder of 162.
Put 2 as the next digit of the answer. 
Result so far: 59560.62
If we subtract 698 from 860, we get 162.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1620, and continue the process.

Going ahead to step 11:
349 can be fit into 1620 4 times, resulting in a remainder of 224.
Write down 4 as next digit of the result. 
Result so far: 59560.624
Deduct 1396 from 1620 and we're left with 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Step 12:
The number 349 fits into 2240 6 times, leaving a remainder of 146.
The number 6 becomes the next digit in our result. 
Result so far: 59560.6246
Subtracting 2094 from 2240 leaves us with 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

On to step 13:
349 can be fit into 1460 4 times, resulting in a remainder of 64.
Write down 4 as next digit of the result. 
Result so far: 59560.62464
Subtracting 1396 from 1460 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 14:
The number 349 fits into 640 1 times, leaving a remainder of 291.
The next digit of our result is 1. 
Result so far: 59560.624641
If we subtract 349 from 640, we get 291.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2910, and continue the process.

On to step 15:
The number 349 fits into 2910 8 times, leaving a remainder of 118.
Put 8 as the next digit of the answer. 
Result so far: 59560.6246418
Subtracting 2792 from 2910 leaves us with 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

On to step 16:
The number 349 fits into 1180 3 times, leaving a remainder of 133.
Record the quotient 3 as the next digit in the result. 
Result so far: 59560.62464183
The remainder is 133 after subtracting 1047 from 1180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1330, and continue the process.

Our division results in 59560.62464183 with a remaining 1.33e-07.
