We look at the division of 80153761 by 634 
The aim is to understand the frequency of 634 in 80153761.

Moving on to step 1:
When dividing 8 by 634, we get 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Append the next digit (0) from the dividend to 8 and continue with: 80 / 634

Moving on to step 2:
634 can be fit into 80 0 times, resulting in a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 80 leaves us with 80.
Fetch the next digit (1) from the dividend, attach it to 80 and continue: 801 / 634

Moving on to step 3:
The number 634 fits into 801 1 times, leaving a remainder of 167.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 634 from 801 leaves us with 167.
Bring next digit (5) of the dividend behind the 167 and repeat the process: 1675 / 634

On to step 4:
When dividing 1675 by 634, we get 2 with a remainder of 407.
Use 2 as the next digit of our solution. 
Result so far: 12.0
If we subtract 1268 from 1675, we get 407.
Append the next digit (3) from the dividend to 407 and continue with: 4073 / 634

On to step 5:
The number 634 fits into 4073 6 times, leaving a remainder of 269.
Put 6 as the next digit of the answer. 
Result so far: 126.0
Subtract 3804 from 4073 to get 269.
Include the next digit (7) from the dividend after 269, then repeat: 2697 / 634

Advancing to step 6:
The number 634 fits into 2697 4 times, leaving a remainder of 161.
The next digit of our result is 4. 
Result so far: 1264.0
Subtracting 2536 from 2697 leaves us with 161.
Grab the next digit (6) from the dividend, add it to 161, then carry on: 1616 / 634

On to step 7:
The number 634 fits into 1616 2 times, leaving a remainder of 348.
Put 2 as the next digit of the answer. 
Result so far: 12642.0
If we subtract 1268 from 1616, we get 348.
Include the next digit (1) from the dividend after 348, then repeat: 3481 / 634

Moving on to step 8:
The number 634 fits into 3481 5 times, leaving a remainder of 311.
The number 5 becomes the next digit in our result. 
Result so far: 126425.0
If we take 3170 away from 3481, we end up with 311.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3110, and continue the process.

Let's proceed to step 9:
634 can be fit into 3110 4 times, resulting in a remainder of 574.
Put 4 as the next digit of the answer. 
Result so far: 126425.4
Subtracting 2536 from 3110 leaves us with 574.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5740, and continue the process.

Advancing to step 10:
When dividing 5740 by 634, we get 9 with a remainder of 34.
The next digit of our result is 9. 
Result so far: 126425.49
Subtracting 5706 from 5740 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 11:
634 goes into 340 0 times with a remainder of 340.
Put 0 as the next digit of the answer. 
Result so far: 126425.49
Subtracting 0 from 340 leaves us with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Going ahead to step 12:
If we divide 3400 by 634, we get 5 and a remainder of 230.
Use 5 as the next digit of our solution. 
Result so far: 126425.4905
Subtracting 3170 from 3400 leaves us with 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Advancing to step 13:
The number 634 fits into 2300 3 times, leaving a remainder of 398.
Use 3 as the next digit of our solution. 
Result so far: 126425.49053
Deduct 1902 from 2300 and we're left with 398.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3980, and continue the process.

Moving on to step 14:
If we divide 3980 by 634, we get 6 and a remainder of 176.
The number 6 becomes the next digit in our result. 
Result so far: 126425.490536
Deduct 3804 from 3980 and we're left with 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

On to step 15:
When dividing 1760 by 634, we get 2 with a remainder of 492.
Record the quotient 2 as the next digit in the result. 
Result so far: 126425.4905362
If we subtract 1268 from 1760, we get 492.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4920, and continue the process.

On to step 16:
When dividing 4920 by 634, we get 7 with a remainder of 482.
Write down 7 as next digit of the result. 
Result so far: 126425.49053627
Subtract 4438 from 4920 to get 482.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4820, and continue the process.

Our division results in 126425.49053627 with a remaining 4.82e-07.
