Let's divide 81435610 by 761
The aim is to understand the frequency of 761 in 81435610.

Advancing to step 1:
8 divided by 761 is 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.
Bring next digit (1) of the dividend behind the 8 and repeat the process: 81 / 761

On to step 2:
If we divide 81 by 761, we get 0 and a remainder of 81.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 81, we get 81.
Take the next digit (4) from the dividend and append it to 81, then repeat: 814 / 761

Going ahead to step 3:
When dividing 814 by 761, we get 1 with a remainder of 53.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 761 from 814 to get 53.
Include the next digit (3) from the dividend after 53, then repeat: 533 / 761

On to step 4:
The number 761 fits into 533 0 times, leaving a remainder of 533.
The next digit of our result is 0. 
Result so far: 10.0
The remainder is 533 after subtracting 0 from 533.
Fetch the next digit (5) from the dividend, attach it to 533 and continue: 5335 / 761

Step 5:
The number 761 fits into 5335 7 times, leaving a remainder of 8.
Write down 7 as next digit of the result. 
Result so far: 107.0
The remainder is 8 after subtracting 5327 from 5335.
Bring next digit (6) of the dividend behind the 8 and repeat the process: 86 / 761

Going ahead to step 6:
When dividing 86 by 761, we get 0 with a remainder of 86.
The number 0 becomes the next digit in our result. 
Result so far: 1070.0
Subtracting 0 from 86 leaves us with 86.
Bring next digit (1) of the dividend behind the 86 and repeat the process: 861 / 761

Moving on to step 7:
761 goes into 861 1 times with a remainder of 100.
The number 1 becomes the next digit in our result. 
Result so far: 10701.0
If we subtract 761 from 861, we get 100.
Bring next digit (0) of the dividend behind the 100 and repeat the process: 1000 / 761

On to step 8:
The number 761 fits into 1000 1 times, leaving a remainder of 239.
Use 1 as the next digit of our solution. 
Result so far: 107011.0
The remainder is 239 after subtracting 761 from 1000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2390, and continue the process.

On to step 9:
761 goes into 2390 3 times with a remainder of 107.
Use 3 as the next digit of our solution. 
Result so far: 107011.3
Deduct 2283 from 2390 and we're left with 107.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1070, and continue the process.

On to step 10:
761 can be fit into 1070 1 times, resulting in a remainder of 309.
Record the quotient 1 as the next digit in the result. 
Result so far: 107011.31
If we subtract 761 from 1070, we get 309.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3090, and continue the process.

On to step 11:
If we divide 3090 by 761, we get 4 and a remainder of 46.
Write down 4 as next digit of the result. 
Result so far: 107011.314
Deduct 3044 from 3090 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

On to step 12:
If we divide 460 by 761, we get 0 and a remainder of 460.
The next digit of our result is 0. 
Result so far: 107011.314
Deduct 0 from 460 and we're left with 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Going ahead to step 13:
761 can be fit into 4600 6 times, resulting in a remainder of 34.
The number 6 becomes the next digit in our result. 
Result so far: 107011.31406
Subtract 4566 from 4600 to get 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 14:
761 goes into 340 0 times with a remainder of 340.
The next digit of our result is 0. 
Result so far: 107011.31406
The remainder is 340 after subtracting 0 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Let's proceed to step 15:
3400 divided by 761 is 4 with a remainder of 356.
Use 4 as the next digit of our solution. 
Result so far: 107011.3140604
Subtracting 3044 from 3400 leaves us with 356.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3560, and continue the process.

Let's proceed to step 16:
When dividing 3560 by 761, we get 4 with a remainder of 516.
Record the quotient 4 as the next digit in the result. 
Result so far: 107011.31406044
If we subtract 3044 from 3560, we get 516.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5160, and continue the process.

The final outcome is 107011.31406044, with a leftover of 5.16e-07.
