83475142 ÷ 726 
The aim is to understand the frequency of 726 in 83475142.

Step 1:
When dividing 8 by 726, we get 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Grab the next digit (3) from the dividend, add it to 8, then carry on: 83 / 726

Advancing to step 2:
83 divided by 726 is 0 with a remainder of 83.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 83 after subtracting 0 from 83.
Bring next digit (4) of the dividend behind the 83 and repeat the process: 834 / 726

Moving on to step 3:
The number 726 fits into 834 1 times, leaving a remainder of 108.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 726 from 834, we get 108.
Bring next digit (7) of the dividend behind the 108 and repeat the process: 1087 / 726

Step 4:
If we divide 1087 by 726, we get 1 and a remainder of 361.
Use 1 as the next digit of our solution. 
Result so far: 11.0
Subtracting 726 from 1087 leaves us with 361.
Take the next digit (5) from the dividend and append it to 361, then repeat: 3615 / 726

Moving on to step 5:
When dividing 3615 by 726, we get 4 with a remainder of 711.
Write down 4 as next digit of the result. 
Result so far: 114.0
If we take 2904 away from 3615, we end up with 711.
Include the next digit (1) from the dividend after 711, then repeat: 7111 / 726

Advancing to step 6:
7111 divided by 726 is 9 with a remainder of 577.
The next digit of our result is 9. 
Result so far: 1149.0
Subtract 6534 from 7111 to get 577.
Fetch the next digit (4) from the dividend, attach it to 577 and continue: 5774 / 726

Let's proceed to step 7:
726 goes into 5774 7 times with a remainder of 692.
The number 7 becomes the next digit in our result. 
Result so far: 11497.0
The remainder is 692 after subtracting 5082 from 5774.
Grab the next digit (2) from the dividend, add it to 692, then carry on: 6922 / 726

On to step 8:
If we divide 6922 by 726, we get 9 and a remainder of 388.
The number 9 becomes the next digit in our result. 
Result so far: 114979.0
If we take 6534 away from 6922, we end up with 388.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3880, and continue the process.

Advancing to step 9:
The number 726 fits into 3880 5 times, leaving a remainder of 250.
Put 5 as the next digit of the answer. 
Result so far: 114979.5
Subtracting 3630 from 3880 leaves us with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

On to step 10:
726 goes into 2500 3 times with a remainder of 322.
The number 3 becomes the next digit in our result. 
Result so far: 114979.53
If we take 2178 away from 2500, we end up with 322.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3220, and continue the process.

Let's proceed to step 11:
726 goes into 3220 4 times with a remainder of 316.
Write down 4 as next digit of the result. 
Result so far: 114979.534
If we subtract 2904 from 3220, we get 316.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3160, and continue the process.

Let's proceed to step 12:
3160 divided by 726 is 4 with a remainder of 256.
The number 4 becomes the next digit in our result. 
Result so far: 114979.5344
Deduct 2904 from 3160 and we're left with 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

After the division, we end up with 114979.5344 and a remainder of 0.00256.
