We divide 77186154 by 345
The aim is to understand the frequency of 345 in 77186154.

Let's proceed to step 1:
When dividing 7 by 345, we get 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Bring next digit (7) of the dividend behind the 7 and repeat the process: 77 / 345

Going ahead to step 2:
When dividing 77 by 345, we get 0 with a remainder of 77.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 77, we get 77.
Take the next digit (1) from the dividend and append it to 77, then repeat: 771 / 345

Going ahead to step 3:
771 divided by 345 is 2 with a remainder of 81.
The next digit of our result is 2. 
Result so far: 2.0
If we subtract 690 from 771, we get 81.
Bring next digit (8) of the dividend behind the 81 and repeat the process: 818 / 345

Step 4:
345 goes into 818 2 times with a remainder of 128.
Put 2 as the next digit of the answer. 
Result so far: 22.0
The remainder is 128 after subtracting 690 from 818.
Bring next digit (6) of the dividend behind the 128 and repeat the process: 1286 / 345

Advancing to step 5:
If we divide 1286 by 345, we get 3 and a remainder of 251.
Write down 3 as next digit of the result. 
Result so far: 223.0
If we subtract 1035 from 1286, we get 251.
Bring next digit (1) of the dividend behind the 251 and repeat the process: 2511 / 345

Let's proceed to step 6:
345 goes into 2511 7 times with a remainder of 96.
Record the quotient 7 as the next digit in the result. 
Result so far: 2237.0
If we take 2415 away from 2511, we end up with 96.
Bring next digit (5) of the dividend behind the 96 and repeat the process: 965 / 345

Step 7:
When dividing 965 by 345, we get 2 with a remainder of 275.
Write down 2 as next digit of the result. 
Result so far: 22372.0
Subtracting 690 from 965 leaves us with 275.
Take the next digit (4) from the dividend and append it to 275, then repeat: 2754 / 345

Moving on to step 8:
The number 345 fits into 2754 7 times, leaving a remainder of 339.
Put 7 as the next digit of the answer. 
Result so far: 223727.0
Deduct 2415 from 2754 and we're left with 339.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3390, and continue the process.

Step 9:
3390 divided by 345 is 9 with a remainder of 285.
The number 9 becomes the next digit in our result. 
Result so far: 223727.9
Deduct 3105 from 3390 and we're left with 285.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2850, and continue the process.

Going ahead to step 10:
When dividing 2850 by 345, we get 8 with a remainder of 90.
Put 8 as the next digit of the answer. 
Result so far: 223727.98
Subtracting 2760 from 2850 leaves us with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Going ahead to step 11:
If we divide 900 by 345, we get 2 and a remainder of 210.
Put 2 as the next digit of the answer. 
Result so far: 223727.982
Subtracting 690 from 900 leaves us with 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Advancing to step 12:
2100 divided by 345 is 6 with a remainder of 30.
Put 6 as the next digit of the answer. 
Result so far: 223727.9826
If we take 2070 away from 2100, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 13:
345 goes into 300 0 times with a remainder of 300.
Record the quotient 0 as the next digit in the result. 
Result so far: 223727.9826
Subtracting 0 from 300 leaves us with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Let's proceed to step 14:
3000 divided by 345 is 8 with a remainder of 240.
Use 8 as the next digit of our solution. 
Result so far: 223727.982608
Subtracting 2760 from 3000 leaves us with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Advancing to step 15:
The number 345 fits into 2400 6 times, leaving a remainder of 330.
Write down 6 as next digit of the result. 
Result so far: 223727.9826086
Deduct 2070 from 2400 and we're left with 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Step 16:
When dividing 3300 by 345, we get 9 with a remainder of 195.
Use 9 as the next digit of our solution. 
Result so far: 223727.98260869
The remainder is 195 after subtracting 3105 from 3300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

The final outcome is 223727.98260869, with a leftover of 1.95e-07.
