Let's divide 78451844 by 636
The aim is to understand the frequency of 636 in 78451844.

Let's proceed to step 1:
7 divided by 636 is 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 636

Let's proceed to step 2:
636 can be fit into 78 0 times, resulting in a remainder of 78.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 78 to get 78.
Take the next digit (4) from the dividend and append it to 78, then repeat: 784 / 636

Moving on to step 3:
636 can be fit into 784 1 times, resulting in a remainder of 148.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 148 after subtracting 636 from 784.
Append the next digit (5) from the dividend to 148 and continue with: 1485 / 636

Let's proceed to step 4:
636 goes into 1485 2 times with a remainder of 213.
Put 2 as the next digit of the answer. 
Result so far: 12.0
Deduct 1272 from 1485 and we're left with 213.
Include the next digit (1) from the dividend after 213, then repeat: 2131 / 636

Advancing to step 5:
636 goes into 2131 3 times with a remainder of 223.
The number 3 becomes the next digit in our result. 
Result so far: 123.0
If we subtract 1908 from 2131, we get 223.
Take the next digit (8) from the dividend and append it to 223, then repeat: 2238 / 636

Advancing to step 6:
If we divide 2238 by 636, we get 3 and a remainder of 330.
The number 3 becomes the next digit in our result. 
Result so far: 1233.0
Subtracting 1908 from 2238 leaves us with 330.
Include the next digit (4) from the dividend after 330, then repeat: 3304 / 636

Advancing to step 7:
3304 divided by 636 is 5 with a remainder of 124.
Write down 5 as next digit of the result. 
Result so far: 12335.0
Subtract 3180 from 3304 to get 124.
Append the next digit (4) from the dividend to 124 and continue with: 1244 / 636

Advancing to step 8:
1244 divided by 636 is 1 with a remainder of 608.
Put 1 as the next digit of the answer. 
Result so far: 123351.0
Subtract 636 from 1244 to get 608.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6080, and continue the process.

Let's proceed to step 9:
636 can be fit into 6080 9 times, resulting in a remainder of 356.
Write down 9 as next digit of the result. 
Result so far: 123351.9
Deduct 5724 from 6080 and we're left 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.

Step 10:
636 goes into 3560 5 times with a remainder of 380.
The next digit of our result is 5. 
Result so far: 123351.95
If we subtract 3180 from 3560, we get 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Moving on to step 11:
If we divide 3800 by 636, we get 5 and a remainder of 620.
Use 5 as the next digit of our solution. 
Result so far: 123351.955
Subtracting 3180 from 3800 leaves us with 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

Our division results in 123351.955 with a remaining 0.062.
