We're dividing 7707243 by 153 
The aim is to understand the frequency of 153 in 7707243.

Going ahead to step 1:
If we divide 7 by 153, we get 0 and a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Fetch the next digit (7) from the dividend, attach it to 7 and continue: 77 / 153

Advancing to step 2:
The number 153 fits into 77 0 times, leaving a remainder of 77.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 77, we get 77.
Fetch the next digit (0) from the dividend, attach it to 77 and continue: 770 / 153

Moving on to step 3:
770 divided by 153 is 5 with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Deduct 765 from 770 and we're left with 5.
Bring next digit (7) of the dividend behind the 5 and repeat the process: 57 / 153

Let's proceed to step 4:
The number 153 fits into 57 0 times, leaving a remainder of 57.
The number 0 becomes the next digit in our result. 
Result so far: 50.0
Subtract 0 from 57 to get 57.
Take the next digit (2) from the dividend and append it to 57, then repeat: 572 / 153

Advancing to step 5:
The number 153 fits into 572 3 times, leaving a remainder of 113.
The next digit of our result is 3. 
Result so far: 503.0
Subtract 459 from 572 to get 113.
Include the next digit (4) from the dividend after 113, then repeat: 1134 / 153

Step 6:
1134 divided by 153 is 7 with a remainder of 63.
Write down 7 as next digit of the result. 
Result so far: 5037.0
Subtracting 1071 from 1134 leaves us with 63.
Grab the next digit (3) from the dividend, add it to 63, then carry on: 633 / 153

On to step 7:
If we divide 633 by 153, we get 4 and a remainder of 21.
Put 4 as the next digit of the answer. 
Result so far: 50374.0
Subtract 612 from 633 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Moving on to step 8:
When dividing 210 by 153, we get 1 with a remainder of 57.
Record the quotient 1 as the next digit in the result. 
Result so far: 50374.1
Subtract 153 from 210 to get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Step 9:
153 goes into 570 3 times with a remainder of 111.
The number 3 becomes the next digit in our result. 
Result so far: 50374.13
If we subtract 459 from 570, we get 111.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1110, and continue the process.

Going ahead to step 10:
If we divide 1110 by 153, we get 7 and a remainder of 39.
The next digit of our result is 7. 
Result so far: 50374.137
The remainder is 39 after subtracting 1071 from 1110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Advancing to step 11:
153 goes into 390 2 times with a remainder of 84.
Put 2 as the next digit of the answer. 
Result so far: 50374.1372
Subtracting 306 from 390 leaves us with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Let's proceed to step 12:
The number 153 fits into 840 5 times, leaving a remainder of 75.
Record the quotient 5 as the next digit in the result. 
Result so far: 50374.13725
Deduct 765 from 840 and we're left with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Going ahead to step 13:
The number 153 fits into 750 4 times, leaving a remainder of 138.
Record the quotient 4 as the next digit in the result. 
Result so far: 50374.137254
Subtracting 612 from 750 leaves us with 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

Going ahead to step 14:
The number 153 fits into 1380 9 times, leaving a remainder of 3.
Record the quotient 9 as the next digit in the result. 
Result so far: 50374.1372549
The remainder is 3 after subtracting 1377 from 1380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 15:
The number 153 fits into 30 0 times, leaving a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 50374.1372549
If we subtract 0 from 30, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

The final result is 50374.1372549 with a remainder of 3e-08.
