78485919 ÷ 536 
The aim is to understand the frequency of 536 in 78485919.

Step 1:
536 goes into 7 0 times with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 536

Step 2:
78 divided by 536 is 0 with a remainder of 78.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 78 leaves us with 78.
Fetch the next digit (4) from the dividend, attach it to 78 and continue: 784 / 536

Going ahead to step 3:
When dividing 784 by 536, we get 1 with a remainder of 248.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 536 from 784, we get 248.
Fetch the next digit (8) from the dividend, attach it to 248 and continue: 2488 / 536

Let's proceed to step 4:
536 can be fit into 2488 4 times, resulting in a remainder of 344.
Put 4 as the next digit of the answer. 
Result so far: 14.0
If we take 2144 away from 2488, we end up with 344.
Grab the next digit (5) from the dividend, add it to 344, then carry on: 3445 / 536

Advancing to step 5:
536 goes into 3445 6 times with a remainder of 229.
The next digit of our result is 6. 
Result so far: 146.0
If we subtract 3216 from 3445, we get 229.
Bring next digit (9) of the dividend behind the 229 and repeat the process: 2299 / 536

Let's proceed to step 6:
When dividing 2299 by 536, we get 4 with a remainder of 155.
Use 4 as the next digit of our solution. 
Result so far: 1464.0
The remainder is 155 after subtracting 2144 from 2299.
Append the next digit (1) from the dividend to 155 and continue with: 1551 / 536

Let's proceed to step 7:
536 goes into 1551 2 times with a remainder of 479.
Write down 2 as next digit of the result. 
Result so far: 14642.0
Deduct 1072 from 1551 and we're left with 479.
Take the next digit (9) from the dividend and append it to 479, then repeat: 4799 / 536

Step 8:
536 can be fit into 4799 8 times, resulting in a remainder of 511.
The next digit of our result is 8. 
Result so far: 146428.0
Subtract 4288 from 4799 to get 511.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5110, and continue the process.

Moving on to step 9:
If we divide 5110 by 536, we get 9 and a remainder of 286.
The number 9 becomes the next digit in our result. 
Result so far: 146428.9
If we take 4824 away from 5110, we end up with 286.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2860, and continue the process.

Let's proceed to step 10:
536 can be fit into 2860 5 times, resulting in a remainder of 180.
Write down 5 as next digit of the result. 
Result so far: 146428.95
Deduct 2680 from 2860 and we're left with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Let's proceed to step 11:
The number 536 fits into 1800 3 times, leaving a remainder of 192.
The next digit of our result is 3. 
Result so far: 146428.953
Deduct 1608 from 1800 and we're left with 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Moving on to step 12:
When dividing 1920 by 536, we get 3 with a remainder of 312.
Put 3 as the next digit of the answer. 
Result so far: 146428.9533
Subtracting 1608 from 1920 leaves us with 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

The final result is 146428.9533 with a remainder of 0.00312.
