74618720 ÷ 306 
The aim is to understand the frequency of 306 in 74618720.

Let's proceed to step 1:
306 can be fit into 7 0 times, resulting in a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Fetch the next digit (4) from the dividend, attach it to 7 and continue: 74 / 306

Let's proceed to step 2:
306 goes into 74 0 times with a remainder of 74.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 74 and we're left with 74.
Take the next digit (6) from the dividend and append it to 74, then repeat: 746 / 306

Going ahead to step 3:
746 divided by 306 is 2 with a remainder of 134.
Use 2 as the next digit of our solution. 
Result so far: 2.0
The remainder is 134 after subtracting 612 from 746.
Grab the next digit (1) from the dividend, add it to 134, then carry on: 1341 / 306

Let's proceed to step 4:
The number 306 fits into 1341 4 times, leaving a remainder of 117.
Write down 4 as next digit of the result. 
Result so far: 24.0
If we take 1224 away from 1341, we end up with 117.
Include the next digit (8) from the dividend after 117, then repeat: 1178 / 306

Going ahead to step 5:
When dividing 1178 by 306, we get 3 with a remainder of 260.
Record the quotient 3 as the next digit in the result. 
Result so far: 243.0
If we subtract 918 from 1178, we get 260.
Grab the next digit (7) from the dividend, add it to 260, then carry on: 2607 / 306

Going ahead to step 6:
The number 306 fits into 2607 8 times, leaving a remainder of 159.
Use 8 as the next digit of our solution. 
Result so far: 2438.0
Subtract 2448 from 2607 to get 159.
Take the next digit (2) from the dividend and append it to 159, then repeat: 1592 / 306

On to step 7:
1592 divided by 306 is 5 with a remainder of 62.
Record the quotient 5 as the next digit in the result. 
Result so far: 24385.0
Subtracting 1530 from 1592 leaves us with 62.
Fetch the next digit (0) from the dividend, attach it to 62 and continue: 620 / 306

Moving on to step 8:
When dividing 620 by 306, we get 2 with a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 243852.0
Subtracting 612 from 620 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 9:
If we divide 80 by 306, we get 0 and a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 243852.0
If we subtract 0 from 80, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 10:
The number 306 fits into 800 2 times, leaving a remainder of 188.
Record the quotient 2 as the next digit in the result. 
Result so far: 243852.02
If we take 612 away from 800, we end up with 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Advancing to step 11:
306 can be fit into 1880 6 times, resulting in a remainder of 44.
Put 6 as the next digit of the answer. 
Result so far: 243852.026
The remainder is 44 after subtracting 1836 from 1880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 12:
306 goes into 440 1 times with a remainder of 134.
Write down 1 as next digit of the result. 
Result so far: 243852.0261
Subtracting 306 from 440 leaves us with 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

Let's proceed to step 13:
1340 divided by 306 is 4 with a remainder of 116.
The number 4 becomes the next digit in our result. 
Result so far: 243852.02614
The remainder is 116 after subtracting 1224 from 1340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Going ahead to step 14:
When dividing 1160 by 306, we get 3 with a remainder of 242.
Record the quotient 3 as the next digit in the result. 
Result so far: 243852.026143
If we take 918 away from 1160, we end up with 242.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2420, and continue the process.

On to step 15:
When dividing 2420 by 306, we get 7 with a remainder of 278.
Record the quotient 7 as the next digit in the result. 
Result so far: 243852.0261437
If we take 2142 away from 2420, we end up with 278.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2780, and continue the process.

Step 16:
The number 306 fits into 2780 9 times, leaving a remainder of 26.
Record the quotient 9 as the next digit in the result. 
Result so far: 243852.02614379
If we subtract 2754 from 2780, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

The final result is 243852.02614379 with a remainder of 2.6e-08.
