We're dividing 76621846 by 153 
The aim is to understand the frequency of 153 in 76621846.

Advancing to step 1:
The number 153 fits into 7 0 times, leaving a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Grab the next digit (6) from the dividend, add it to 7, then carry on: 76 / 153

On to step 2:
If we divide 76 by 153, we get 0 and a remainder of 76.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 76 after subtracting 0 from 76.
Take the next digit (6) from the dividend and append it to 76, then repeat: 766 / 153

Moving on to step 3:
766 divided by 153 is 5 with a remainder of 1.
Put 5 as the next digit of the answer. 
Result so far: 5.0
If we subtract 765 from 766, we get 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 153

Let's proceed to step 4:
The number 153 fits into 12 0 times, leaving a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 50.0
Subtracting 0 from 12 leaves us with 12.
Append the next digit (1) from the dividend to 12 and continue with: 121 / 153

Going ahead to step 5:
If we divide 121 by 153, we get 0 and a remainder of 121.
The number 0 becomes the next digit in our result. 
Result so far: 500.0
The remainder is 121 after subtracting 0 from 121.
Bring next digit (8) of the dividend behind the 121 and repeat the process: 1218 / 153

Advancing to step 6:
1218 divided by 153 is 7 with a remainder of 147.
Write down 7 as next digit of the result. 
Result so far: 5007.0
Subtract 1071 from 1218 to get 147.
Append the next digit (4) from the dividend to 147 and continue with: 1474 / 153

Step 7:
153 can be fit into 1474 9 times, resulting in a remainder of 97.
Use 9 as the next digit of our solution. 
Result so far: 50079.0
If we take 1377 away from 1474, we end up with 97.
Include the next digit (6) from the dividend after 97, then repeat: 976 / 153

Going ahead to step 8:
If we divide 976 by 153, we get 6 and a remainder of 58.
The next digit of our result is 6. 
Result so far: 500796.0
The remainder is 58 after subtracting 918 from 976.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Going ahead to step 9:
If we divide 580 by 153, we get 3 and a remainder of 121.
The number 3 becomes the next digit in our result. 
Result so far: 500796.3
The remainder is 121 after subtracting 459 from 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1210, and continue the process.

Advancing to step 10:
153 can be fit into 1210 7 times, resulting in a remainder of 139.
The next digit of our result is 7. 
Result so far: 500796.37
Deduct 1071 from 1210 and we're left with 139.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1390, and continue the process.

Going ahead to step 11:
If we divide 1390 by 153, we get 9 and a remainder of 13.
Write down 9 as next digit of the result. 
Result so far: 500796.379
Subtract 1377 from 1390 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 12:
153 can be fit into 130 0 times, resulting in a remainder of 130.
Use 0 as the next digit of our solution. 
Result so far: 500796.379
Subtracting 0 from 130 leaves us with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Advancing to step 13:
153 can be fit into 1300 8 times, resulting in a remainder of 76.
Write down 8 as next digit of the result. 
Result so far: 500796.37908
Deduct 1224 from 1300 and we're left with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Moving on to step 14:
The number 153 fits into 760 4 times, leaving a remainder of 148.
The number 4 becomes the next digit in our result. 
Result so far: 500796.379084
Deduct 612 from 760 and we're left with 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Advancing to step 15:
If we divide 1480 by 153, we get 9 and a remainder of 103.
Record the quotient 9 as the next digit in the result. 
Result so far: 500796.3790849
Deduct 1377 from 1480 and we're left with 103.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1030, and continue the process.

Moving on to step 16:
1030 divided by 153 is 6 with a remainder of 112.
Write down 6 as next digit of the result. 
Result so far: 500796.37908496
Deduct 918 from 1030 and we're left with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

After the division, we end up with 500796.37908496 and a remainder of 1.12e-07.
