70629770 divided by 306 
The aim is to understand the frequency of 306 in 70629770.

On to step 1:
If we divide 7 by 306, we get 0 and a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Include the next digit (0) from the dividend after 7, then repeat: 70 / 306

Moving on to step 2:
70 divided by 306 is 0 with a remainder of 70.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 70 and we're left with 70.
Grab the next digit (6) from the dividend, add it to 70, then carry on: 706 / 306

Moving on to step 3:
306 can be fit into 706 2 times, resulting in a remainder of 94.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 612 from 706 and we're left with 94.
Bring next digit (2) of the dividend behind the 94 and repeat the process: 942 / 306

Going ahead to step 4:
306 can be fit into 942 3 times, resulting in a remainder of 24.
The number 3 becomes the next digit in our result. 
Result so far: 23.0
Deduct 918 from 942 and we're left with 24.
Append the next digit (9) from the dividend to 24 and continue with: 249 / 306

Advancing to step 5:
When dividing 249 by 306, we get 0 with a remainder of 249.
Put 0 as the next digit of the answer. 
Result so far: 230.0
Deduct 0 from 249 and we're left with 249.
Fetch the next digit (7) from the dividend, attach it to 249 and continue: 2497 / 306

Going ahead to step 6:
306 can be fit into 2497 8 times, resulting in a remainder of 49.
The next digit of our result is 8. 
Result so far: 2308.0
The remainder is 49 after subtracting 2448 from 2497.
Take the next digit (7) from the dividend and append it to 49, then repeat: 497 / 306

Moving on to step 7:
497 divided by 306 is 1 with a remainder of 191.
Write down 1 as next digit of the result. 
Result so far: 23081.0
If we take 306 away from 497, we end up with 191.
Fetch the next digit (0) from the dividend, attach it to 191 and continue: 1910 / 306

Moving on to step 8:
The number 306 fits into 1910 6 times, leaving a remainder of 74.
Write down 6 as next digit of the result. 
Result so far: 230816.0
Deduct 1836 from 1910 and we're left with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

On to step 9:
306 can be fit into 740 2 times, resulting in a remainder of 128.
The number 2 becomes the next digit in our result. 
Result so far: 230816.2
If we take 612 away from 740, we end up with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

On to step 10:
306 can be fit into 1280 4 times, resulting in a remainder of 56.
The next digit of our result is 4. 
Result so far: 230816.24
Subtract 1224 from 1280 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Step 11:
560 divided by 306 is 1 with a remainder of 254.
The number 1 becomes the next digit in our result. 
Result so far: 230816.241
Subtracting 306 from 560 leaves us with 254.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2540, and continue the process.

Going ahead to step 12:
2540 divided by 306 is 8 with a remainder of 92.
Write down 8 as next digit of the result. 
Result so far: 230816.2418
If we take 2448 away from 2540, we end up with 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Advancing to step 13:
When dividing 920 by 306, we get 3 with a remainder of 2.
Write down 3 as next digit of the result. 
Result so far: 230816.24183
The remainder is 2 after subtracting 918 from 920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 14:
When dividing 20 by 306, we get 0 with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 230816.24183
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 15:
The number 306 fits into 200 0 times, leaving a remainder of 200.
Use 0 as the next digit of our solution. 
Result so far: 230816.24183
If we subtract 0 from 200, we get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

In conclusion, the division gives 230816.24183 with a balance of 2e-06.
