We look at the division of 81058584 by 634 
The aim is to understand the frequency of 634 in 81058584.

Moving on to step 1:
The number 634 fits into 8 0 times, leaving a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Bring next digit (1) of the dividend behind the 8 and repeat the process: 81 / 634

Let's proceed to step 2:
The number 634 fits into 81 0 times, leaving a remainder of 81.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 81, we get 81.
Grab the next digit (0) from the dividend, add it to 81, then carry on: 810 / 634

Step 3:
634 goes into 810 1 times with a remainder of 176.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 634 from 810, we get 176.
Take the next digit (5) from the dividend and append it to 176, then repeat: 1765 / 634

Advancing to step 4:
The number 634 fits into 1765 2 times, leaving a remainder of 497.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
If we take 1268 away from 1765, we end up with 497.
Grab the next digit (8) from the dividend, add it to 497, then carry on: 4978 / 634

Advancing to step 5:
4978 divided by 634 is 7 with a remainder of 540.
The next digit of our result is 7. 
Result so far: 127.0
The remainder is 540 after subtracting 4438 from 4978.
Bring next digit (5) of the dividend behind the 540 and repeat the process: 5405 / 634

Step 6:
When dividing 5405 by 634, we get 8 with a remainder of 333.
Record the quotient 8 as the next digit in the result. 
Result so far: 1278.0
If we take 5072 away from 5405, we end up with 333.
Fetch the next digit (8) from the dividend, attach it to 333 and continue: 3338 / 634

Moving on to step 7:
When dividing 3338 by 634, we get 5 with a remainder of 168.
The next digit of our result is 5. 
Result so far: 12785.0
Deduct 3170 from 3338 and we're left with 168.
Bring next digit (4) of the dividend behind the 168 and repeat the process: 1684 / 634

Going ahead to step 8:
If we divide 1684 by 634, we get 2 and a remainder of 416.
The number 2 becomes the next digit in our result. 
Result so far: 127852.0
Subtracting 1268 from 1684 leaves us with 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

Advancing to step 9:
634 goes into 4160 6 times with a remainder of 356.
Record the quotient 6 as the next digit in the result. 
Result so far: 127852.6
The remainder is 356 after subtracting 3804 from 4160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3560, and continue the process.

On to step 10:
If we divide 3560 by 634, we get 5 and a remainder of 390.
Put 5 as the next digit of the answer. 
Result so far: 127852.65
The remainder is 390 after subtracting 3170 from 3560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

Moving on to step 11:
If we divide 3900 by 634, we get 6 and a remainder of 96.
Use 6 as the next digit of our solution. 
Result so far: 127852.656
The remainder is 96 after subtracting 3804 from 3900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

On to step 12:
If we divide 960 by 634, we get 1 and a remainder of 326.
The number 1 becomes the next digit in our result. 
Result so far: 127852.6561
Deduct 634 from 960 and we're left with 326.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3260, and continue the process.

On to step 13:
If we divide 3260 by 634, we get 5 and a remainder of 90.
Write down 5 as next digit of the result. 
Result so far: 127852.65615
Subtract 3170 from 3260 to get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

On to step 14:
634 goes into 900 1 times with a remainder of 266.
The number 1 becomes the next digit in our result. 
Result so far: 127852.656151
If we take 634 away from 900, we end up with 266.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2660, and continue the process.

Advancing to step 15:
When dividing 2660 by 634, we get 4 with a remainder of 124.
The number 4 becomes the next digit in our result. 
Result so far: 127852.6561514
Deduct 2536 from 2660 and we're left with 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

Advancing to step 16:
The number 634 fits into 1240 1 times, leaving a remainder of 606.
Put 1 as the next digit of the answer. 
Result so far: 127852.65615141
Subtracting 634 from 1240 leaves us with 606.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6060, and continue the process.

After the division, we end up with 127852.65615141 and a remainder of 6.06e-07.
