78924976 ÷ 349 
The aim is to understand the frequency of 349 in 78924976.

Advancing to step 1:
7 divided by 349 is 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 349

On to step 2:
When dividing 78 by 349, we get 0 with a remainder of 78.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 78 after subtracting 0 from 78.
Take the next digit (9) from the dividend and append it to 78, then repeat: 789 / 349

Moving on to step 3:
The number 349 fits into 789 2 times, leaving a remainder of 91.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
The remainder is 91 after subtracting 698 from 789.
Fetch the next digit (2) from the dividend, attach it to 91 and continue: 912 / 349

Moving on to step 4:
349 goes into 912 2 times with a remainder of 214.
Record the quotient 2 as the next digit in the result. 
Result so far: 22.0
Deduct 698 from 912 and we're left with 214.
Grab the next digit (4) from the dividend, add it to 214, then carry on: 2144 / 349

Going ahead to step 5:
2144 divided by 349 is 6 with a remainder of 50.
Use 6 as the next digit of our solution. 
Result so far: 226.0
Subtract 2094 from 2144 to get 50.
Fetch the next digit (9) from the dividend, attach it to 50 and continue: 509 / 349

Step 6:
509 divided by 349 is 1 with a remainder of 160.
The number 1 becomes the next digit in our result. 
Result so far: 2261.0
Deduct 349 from 509 and we're left with 160.
Bring next digit (7) of the dividend behind the 160 and repeat the process: 1607 / 349

On to step 7:
If we divide 1607 by 349, we get 4 and a remainder of 211.
Use 4 as the next digit of our solution. 
Result so far: 22614.0
If we subtract 1396 from 1607, we get 211.
Append the next digit (6) from the dividend to 211 and continue with: 2116 / 349

Let's proceed to step 8:
The number 349 fits into 2116 6 times, leaving a remainder of 22.
The number 6 becomes the next digit in our result. 
Result so far: 226146.0
The remainder is 22 after subtracting 2094 from 2116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 9:
When dividing 220 by 349, we get 0 with a remainder of 220.
Record the quotient 0 as the next digit in the result. 
Result so far: 226146.0
Subtracting 0 from 220 leaves us with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Let's proceed to step 10:
The number 349 fits into 2200 6 times, leaving a remainder of 106.
Use 6 as the next digit of our solution. 
Result so far: 226146.06
Deduct 2094 from 2200 and we're left with 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Let's proceed to step 11:
When dividing 1060 by 349, we get 3 with a remainder of 13.
Record the quotient 3 as the next digit in the result. 
Result so far: 226146.063
The remainder is 13 after subtracting 1047 from 1060.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 12:
If we divide 130 by 349, we get 0 and a remainder of 130.
The number 0 becomes the next digit in our result. 
Result so far: 226146.063
The remainder is 130 after subtracting 0 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Let's proceed to step 13:
349 can be fit into 1300 3 times, resulting in a remainder of 253.
Record the quotient 3 as the next digit in the result. 
Result so far: 226146.06303
Deduct 1047 from 1300 and we're left with 253.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2530, and continue the process.

Advancing to step 14:
2530 divided by 349 is 7 with a remainder of 87.
Record the quotient 7 as the next digit in the result. 
Result so far: 226146.063037
Subtract 2443 from 2530 to get 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Moving on to step 15:
349 goes into 870 2 times with a remainder of 172.
Put 2 as the next digit of the answer. 
Result so far: 226146.0630372
If we take 698 away from 870, we end up with 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Advancing to step 16:
1720 divided by 349 is 4 with a remainder of 324.
The number 4 becomes the next digit in our result. 
Result so far: 226146.06303724
Subtracting 1396 from 1720 leaves us with 324.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3240, and continue the process.

The final outcome is 226146.06303724, with a leftover of 3.24e-07.
