72373870 divided by 305 
The aim is to understand the frequency of 305 in 72373870.

Advancing to step 1:
The number 305 fits into 7 0 times, leaving a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Grab the next digit (2) from the dividend, add it to 7, then carry on: 72 / 305

Advancing to step 2:
305 goes into 72 0 times with a remainder of 72.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 72 after subtracting 0 from 72.
Grab the next digit (3) from the dividend, add it to 72, then carry on: 723 / 305

Moving on to step 3:
305 goes into 723 2 times with a remainder of 113.
The next digit of our result is 2. 
Result so far: 2.0
The remainder is 113 after subtracting 610 from 723.
Take the next digit (7) from the dividend and append it to 113, then repeat: 1137 / 305

On to step 4:
If we divide 1137 by 305, we get 3 and a remainder of 222.
Use 3 as the next digit of our solution. 
Result so far: 23.0
Subtracting 915 from 1137 leaves us with 222.
Fetch the next digit (3) from the dividend, attach it to 222 and continue: 2223 / 305

Moving on to step 5:
If we divide 2223 by 305, we get 7 and a remainder of 88.
Record the quotient 7 as the next digit in the result. 
Result so far: 237.0
Deduct 2135 from 2223 and we're left with 88.
Grab the next digit (8) from the dividend, add it to 88, then carry on: 888 / 305

Let's proceed to step 6:
If we divide 888 by 305, we get 2 and a remainder of 278.
The next digit of our result is 2. 
Result so far: 2372.0
Deduct 610 from 888 and we're left with 278.
Bring next digit (7) of the dividend behind the 278 and repeat the process: 2787 / 305

Let's proceed to step 7:
305 goes into 2787 9 times with a remainder of 42.
Write down 9 as next digit of the result. 
Result so far: 23729.0
Deduct 2745 from 2787 and we're left with 42.
Fetch the next digit (0) from the dividend, attach it to 42 and continue: 420 / 305

Let's proceed to step 8:
The number 305 fits into 420 1 times, leaving a remainder of 115.
The number 1 becomes the next digit in our result. 
Result so far: 237291.0
Subtract 305 from 420 to get 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

On to step 9:
If we divide 1150 by 305, we get 3 and a remainder of 235.
Write down 3 as next digit of the result. 
Result so far: 237291.3
The remainder is 235 after subtracting 915 from 1150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2350, and continue the process.

Moving on to step 10:
2350 divided by 305 is 7 with a remainder of 215.
The number 7 becomes the next digit in our result. 
Result so far: 237291.37
Subtracting 2135 from 2350 leaves us with 215.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2150, and continue the process.

Going ahead to step 11:
The number 305 fits into 2150 7 times, leaving a remainder of 15.
Write down 7 as next digit of the result. 
Result so far: 237291.377
Deduct 2135 from 2150 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

The quotient of the division is 237291.377, and the remainder is 0.0015.
