77626043 ÷ 306 
The aim is to understand the frequency of 306 in 77626043.

Advancing to step 1:
The number 306 fits into 7 0 times, leaving a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Grab the next digit (7) from the dividend, add it to 7, then carry on: 77 / 306

Step 2:
77 divided by 306 is 0 with a remainder of 77.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 77 to get 77.
Take the next digit (6) from the dividend and append it to 77, then repeat: 776 / 306

Step 3:
776 divided by 306 is 2 with a remainder of 164.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we subtract 612 from 776, we get 164.
Bring next digit (2) of the dividend behind the 164 and repeat the process: 1642 / 306

Moving on to step 4:
306 goes into 1642 5 times with a remainder of 112.
The number 5 becomes the next digit in our result. 
Result so far: 25.0
If we subtract 1530 from 1642, we get 112.
Grab the next digit (6) from the dividend, add it to 112, then carry on: 1126 / 306

Going ahead to step 5:
The number 306 fits into 1126 3 times, leaving a remainder of 208.
Record the quotient 3 as the next digit in the result. 
Result so far: 253.0
If we take 918 away from 1126, we end up with 208.
Fetch the next digit (0) from the dividend, attach it to 208 and continue: 2080 / 306

On to step 6:
If we divide 2080 by 306, we get 6 and a remainder of 244.
The number 6 becomes the next digit in our result. 
Result so far: 2536.0
The remainder is 244 after subtracting 1836 from 2080.
Grab the next digit (4) from the dividend, add it to 244, then carry on: 2444 / 306

Step 7:
306 goes into 2444 7 times with a remainder of 302.
Write down 7 as next digit of the result. 
Result so far: 25367.0
If we take 2142 away from 2444, we end up with 302.
Fetch the next digit (3) from the dividend, attach it to 302 and continue: 3023 / 306

Moving on to step 8:
When dividing 3023 by 306, we get 9 with a remainder of 269.
Use 9 as the next digit of our solution. 
Result so far: 253679.0
Subtracting 2754 from 3023 leaves us with 269.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2690, and continue the process.

On to step 9:
306 goes into 2690 8 times with a remainder of 242.
Use 8 as the next digit of our solution. 
Result so far: 253679.8
Deduct 2448 from 2690 and we're left 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.

Moving on to step 10:
When dividing 2420 by 306, we get 7 with a remainder of 278.
Use 7 as the next digit of our solution. 
Result so far: 253679.87
If we subtract 2142 from 2420, we get 278.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2780, and continue the process.

Going ahead to step 11:
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: 253679.879
Subtracting 2754 from 2780 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 12:
306 goes into 260 0 times with a remainder of 260.
Record the quotient 0 as the next digit in the result. 
Result so far: 253679.879
If we subtract 0 from 260, we get 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Step 13:
306 goes into 2600 8 times with a remainder of 152.
Record the quotient 8 as the next digit in the result. 
Result so far: 253679.87908
If we take 2448 away from 2600, we end up with 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Let's proceed to step 14:
306 can be fit into 1520 4 times, resulting in a remainder of 296.
Record the quotient 4 as the next digit in the result. 
Result so far: 253679.879084
If we take 1224 away from 1520, we end up with 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

On to step 15:
2960 divided by 306 is 9 with a remainder of 206.
Write down 9 as next digit of the result. 
Result so far: 253679.8790849
Subtracting 2754 from 2960 leaves us with 206.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2060, and continue the process.

Going ahead to step 16:
If we divide 2060 by 306, we get 6 and a remainder of 224.
Write down 6 as next digit of the result. 
Result so far: 253679.87908496
If we subtract 1836 from 2060, we get 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

After the division, we end up with 253679.87908496 and a remainder of 2.24e-07.
