We divide 78990747 by 636
We're looking to find how many times 636 goes into 78990747.

Step 1:
When dividing 7 by 636, we get 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
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 / 636

Advancing to step 2:
636 goes into 78 0 times with a remainder of 78.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 78, we get 78.
Bring next digit (9) of the dividend behind the 78 and repeat the process: 789 / 636

Moving on to step 3:
636 can be fit into 789 1 times, resulting in a remainder of 153.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 636 from 789, we get 153.
Append the next digit (9) from the dividend to 153 and continue with: 1539 / 636

Going ahead to step 4:
The number 636 fits into 1539 2 times, leaving a remainder of 267.
Use 2 as the next digit of our solution. 
Result so far: 12.0
If we take 1272 away from 1539, we end up with 267.
Bring next digit (0) of the dividend behind the 267 and repeat the process: 2670 / 636

On to step 5:
2670 divided by 636 is 4 with a remainder of 126.
The number 4 becomes the next digit in our result. 
Result so far: 124.0
If we take 2544 away from 2670, we end up with 126.
Take the next digit (7) from the dividend and append it to 126, then repeat: 1267 / 636

Let's proceed to step 6:
When dividing 1267 by 636, we get 1 with a remainder of 631.
The next digit of our result is 1. 
Result so far: 1241.0
The remainder is 631 after subtracting 636 from 1267.
Include the next digit (4) from the dividend after 631, then repeat: 6314 / 636

Let's proceed to step 7:
When dividing 6314 by 636, we get 9 with a remainder of 590.
Record the quotient 9 as the next digit in the result. 
Result so far: 12419.0
Deduct 5724 from 6314 and we're left with 590.
Include the next digit (7) from the dividend after 590, then repeat: 5907 / 636

Let's proceed to step 8:
5907 divided by 636 is 9 with a remainder of 183.
Use 9 as the next digit of our solution. 
Result so far: 124199.0
Subtract 5724 from 5907 to get 183.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1830, and continue the process.

Moving on to step 9:
636 goes into 1830 2 times with a remainder of 558.
The next digit of our result is 2. 
Result so far: 124199.2
Subtract 1272 from 1830 to get 558.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5580, and continue the process.

Let's proceed to step 10:
5580 divided by 636 is 8 with a remainder of 492.
Record the quotient 8 as the next digit in the result. 
Result so far: 124199.28
The remainder is 492 after subtracting 5088 from 5580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4920, and continue the process.

On to step 11:
636 can be fit into 4920 7 times, resulting in a remainder of 468.
Use 7 as the next digit of our solution. 
Result so far: 124199.287
Deduct 4452 from 4920 and we're left with 468.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4680, and continue the process.

Moving on to step 12:
If we divide 4680 by 636, we get 7 and a remainder of 228.
Use 7 as the next digit of our solution. 
Result so far: 124199.2877
The remainder is 228 after subtracting 4452 from 4680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

After the division, we end up with 124199.2877 and a remainder of 0.00228.
