We look at the division of 86715590 by 744 
The aim is to understand the frequency of 744 in 86715590.

Moving on to step 1:
If we divide 8 by 744, we get 0 and a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Bring next digit (6) of the dividend behind the 8 and repeat the process: 86 / 744

Advancing to step 2:
If we divide 86 by 744, we get 0 and a remainder of 86.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 86 and we're left with 86.
Bring next digit (7) of the dividend behind the 86 and repeat the process: 867 / 744

On to step 3:
If we divide 867 by 744, we get 1 and a remainder of 123.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 744 from 867 leaves us with 123.
Include the next digit (1) from the dividend after 123, then repeat: 1231 / 744

On to step 4:
1231 divided by 744 is 1 with a remainder of 487.
Write down 1 as next digit of the result. 
Result so far: 11.0
The remainder is 487 after subtracting 744 from 1231.
Fetch the next digit (5) from the dividend, attach it to 487 and continue: 4875 / 744

Let's proceed to step 5:
744 can be fit into 4875 6 times, resulting in a remainder of 411.
Record the quotient 6 as the next digit in the result. 
Result so far: 116.0
Subtract 4464 from 4875 to get 411.
Bring next digit (5) of the dividend behind the 411 and repeat the process: 4115 / 744

Moving on to step 6:
744 goes into 4115 5 times with a remainder of 395.
The number 5 becomes the next digit in our result. 
Result so far: 1165.0
The remainder is 395 after subtracting 3720 from 4115.
Append the next digit (9) from the dividend to 395 and continue with: 3959 / 744

On to step 7:
If we divide 3959 by 744, we get 5 and a remainder of 239.
Put 5 as the next digit of the answer. 
Result so far: 11655.0
The remainder is 239 after subtracting 3720 from 3959.
Bring next digit (0) of the dividend behind the 239 and repeat the process: 2390 / 744

Step 8:
When dividing 2390 by 744, we get 3 with a remainder of 158.
Record the quotient 3 as the next digit in the result. 
Result so far: 116553.0
If we take 2232 away from 2390, we end up with 158.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

Moving on to step 9:
The number 744 fits into 1580 2 times, leaving a remainder of 92.
Put 2 as the next digit of the answer. 
Result so far: 116553.2
If we subtract 1488 from 1580, we get 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

On to step 10:
When dividing 920 by 744, we get 1 with a remainder of 176.
The next digit of our result is 1. 
Result so far: 116553.21
Deduct 744 from 920 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 11:
1760 divided by 744 is 2 with a remainder of 272.
Record the quotient 2 as the next digit in the result. 
Result so far: 116553.212
If we subtract 1488 from 1760, we get 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

Going ahead to step 12:
When dividing 2720 by 744, we get 3 with a remainder of 488.
Use 3 as the next digit of our solution. 
Result so far: 116553.2123
If we subtract 2232 from 2720, we get 488.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4880, and continue the process.

Step 13:
When dividing 4880 by 744, we get 6 with a remainder of 416.
Use 6 as the next digit of our solution. 
Result so far: 116553.21236
Deduct 4464 from 4880 and we're left 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.

On to step 14:
4160 divided by 744 is 5 with a remainder of 440.
Record the quotient 5 as the next digit in the result. 
Result so far: 116553.212365
If we take 3720 away from 4160, we end up with 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Let's proceed to step 15:
744 goes into 4400 5 times with a remainder of 680.
Record the quotient 5 as the next digit in the result. 
Result so far: 116553.2123655
Subtracting 3720 from 4400 leaves us with 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6800, and continue the process.

The quotient of the division is 116553.2123655, and the remainder is 6.8e-06.
