We're dividing 76449636 by 122 
We want to divide 76449636 by 122.

Step 1:
7 divided by 122 is 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Include the next digit (6) from the dividend after 7, then repeat: 76 / 122

On to step 2:
76 divided by 122 is 0 with a remainder of 76.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 76 and we're left with 76.
Include the next digit (4) from the dividend after 76, then repeat: 764 / 122

Moving on to step 3:
The number 122 fits into 764 6 times, leaving a remainder of 32.
Use 6 as the next digit of our solution. 
Result so far: 6.0
If we take 732 away from 764, we end up with 32.
Grab the next digit (4) from the dividend, add it to 32, then carry on: 324 / 122

Let's proceed to step 4:
122 can be fit into 324 2 times, resulting in a remainder of 80.
Record the quotient 2 as the next digit in the result. 
Result so far: 62.0
The remainder is 80 after subtracting 244 from 324.
Fetch the next digit (9) from the dividend, attach it to 80 and continue: 809 / 122

Moving on to step 5:
122 can be fit into 809 6 times, resulting in a remainder of 77.
The next digit of our result is 6. 
Result so far: 626.0
If we take 732 away from 809, we end up with 77.
Bring next digit (6) of the dividend behind the 77 and repeat the process: 776 / 122

Step 6:
776 divided by 122 is 6 with a remainder of 44.
Write down 6 as next digit of the result. 
Result so far: 6266.0
Subtract 732 from 776 to get 44.
Include the next digit (3) from the dividend after 44, then repeat: 443 / 122

Advancing to step 7:
122 can be fit into 443 3 times, resulting in a remainder of 77.
The next digit of our result is 3. 
Result so far: 62663.0
Deduct 366 from 443 and we're left with 77.
Grab the next digit (6) from the dividend, add it to 77, then carry on: 776 / 122

Advancing to step 8:
122 goes into 776 6 times with a remainder of 44.
Use 6 as the next digit of our solution. 
Result so far: 626636.0
If we subtract 732 from 776, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 9:
If we divide 440 by 122, we get 3 and a remainder of 74.
Use 3 as the next digit of our solution. 
Result so far: 626636.3
The remainder is 74 after subtracting 366 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

On to step 10:
122 can be fit into 740 6 times, resulting in a remainder of 8.
The next digit of our result is 6. 
Result so far: 626636.36
Subtract 732 from 740 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 11:
The number 122 fits into 80 0 times, leaving a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 626636.36
Subtracting 0 from 80 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 12:
122 can be fit into 800 6 times, resulting in a remainder of 68.
Put 6 as the next digit of the answer. 
Result so far: 626636.3606
If we subtract 732 from 800, we get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Let's proceed to step 13:
680 divided by 122 is 5 with a remainder of 70.
Write down 5 as next digit of the result. 
Result so far: 626636.36065
If we subtract 610 from 680, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Step 14:
122 goes into 700 5 times with a remainder of 90.
Put 5 as the next digit of the answer. 
Result so far: 626636.360655
Subtract 610 from 700 to get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

After the division, we end up with 626636.360655 and a remainder of 9e-06.
