We're dividing 77442072 by 909 
We want to figure out the number of times 77442072 can be divided by 909.

Step 1:
The number 909 fits into 7 0 times, leaving a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Take the next digit (7) from the dividend and append it to 7, then repeat: 77 / 909

Advancing to step 2:
909 can be fit into 77 0 times, resulting in a remainder of 77.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 77, we get 77.
Fetch the next digit (4) from the dividend, attach it to 77 and continue: 774 / 909

Advancing to step 3:
If we divide 774 by 909, we get 0 and a remainder of 774.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 774, we get 774.
Append the next digit (4) from the dividend to 774 and continue with: 7744 / 909

Advancing to step 4:
909 goes into 7744 8 times with a remainder of 472.
Write down 8 as next digit of the result. 
Result so far: 8.0
If we take 7272 away from 7744, we end up with 472.
Grab the next digit (2) from the dividend, add it to 472, then carry on: 4722 / 909

Advancing to step 5:
If we divide 4722 by 909, we get 5 and a remainder of 177.
Write down 5 as next digit of the result. 
Result so far: 85.0
Subtracting 4545 from 4722 leaves us with 177.
Append the next digit (0) from the dividend to 177 and continue with: 1770 / 909

Moving on to step 6:
909 can be fit into 1770 1 times, resulting in a remainder of 861.
The next digit of our result is 1. 
Result so far: 851.0
If we take 909 away from 1770, we end up with 861.
Include the next digit (7) from the dividend after 861, then repeat: 8617 / 909

Going ahead to step 7:
909 goes into 8617 9 times with a remainder of 436.
Write down 9 as next digit of the result. 
Result so far: 8519.0
If we take 8181 away from 8617, we end up with 436.
Grab the next digit (2) from the dividend, add it to 436, then carry on: 4362 / 909

Going ahead to step 8:
When dividing 4362 by 909, we get 4 with a remainder of 726.
The number 4 becomes the next digit in our result. 
Result so far: 85194.0
If we take 3636 away from 4362, we end up with 726.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7260, and continue the process.

Let's proceed to step 9:
909 can be fit into 7260 7 times, resulting in a remainder of 897.
Write down 7 as next digit of the result. 
Result so far: 85194.7
Subtract 6363 from 7260 to get 897.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8970, and continue the process.

Step 10:
When dividing 8970 by 909, we get 9 with a remainder of 789.
Record the quotient 9 as the next digit in the result. 
Result so far: 85194.79
Deduct 8181 from 8970 and we're left with 789.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7890, and continue the process.

Moving on to step 11:
When dividing 7890 by 909, we get 8 with a remainder of 618.
Record the quotient 8 as the next digit in the result. 
Result so far: 85194.798
Subtracting 7272 from 7890 leaves us with 618.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6180, and continue the process.

Let's proceed to step 12:
909 goes into 6180 6 times with a remainder of 726.
Record the quotient 6 as the next digit in the result. 
Result so far: 85194.7986
Deduct 5454 from 6180 and we're left with 726.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7260, and continue the process.

Moving on to step 13:
909 can be fit into 7260 7 times, resulting in a remainder of 897.
Write down 7 as next digit of the result. 
Result so far: 85194.79867
If we take 6363 away from 7260, we end up with 897.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8970, and continue the process.

Let's proceed to step 14:
8970 divided by 909 is 9 with a remainder of 789.
Use 9 as the next digit of our solution. 
Result so far: 85194.798679
Subtracting 8181 from 8970 leaves us with 789.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7890, and continue the process.

Advancing to step 15:
909 can be fit into 7890 8 times, resulting in a remainder of 618.
Use 8 as the next digit of our solution. 
Result so far: 85194.7986798
The remainder is 618 after subtracting 7272 from 7890.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6180, and continue the process.

Step 16:
909 can be fit into 6180 6 times, resulting in a remainder of 726.
The number 6 becomes the next digit in our result. 
Result so far: 85194.79867986
Subtract 5454 from 6180 to get 726.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7260, and continue the process.

The final result is 85194.79867986 with a remainder of 7.26e-07.
