We're dividing 77245970 by 769 
Our goal is to divide 77245970 by 769.

Let's proceed to step 1:
When dividing 7 by 769, we get 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Append the next digit (7) from the dividend to 7 and continue with: 77 / 769

Advancing to step 2:
769 goes into 77 0 times with a remainder of 77.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 77 after subtracting 0 from 77.
Include the next digit (2) from the dividend after 77, then repeat: 772 / 769

Let's proceed to step 3:
When dividing 772 by 769, we get 1 with a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 3 after subtracting 769 from 772.
Fetch the next digit (4) from the dividend, attach it to 3 and continue: 34 / 769

Going ahead to step 4:
The number 769 fits into 34 0 times, leaving a remainder of 34.
The next digit of our result is 0. 
Result so far: 10.0
Subtract 0 from 34 to get 34.
Fetch the next digit (5) from the dividend, attach it to 34 and continue: 345 / 769

Moving on to step 5:
If we divide 345 by 769, we get 0 and a remainder of 345.
The number 0 becomes the next digit in our result. 
Result so far: 100.0
If we take 0 away from 345, we end up with 345.
Take the next digit (9) from the dividend and append it to 345, then repeat: 3459 / 769

Going ahead to step 6:
The number 769 fits into 3459 4 times, leaving a remainder of 383.
Record the quotient 4 as the next digit in the result. 
Result so far: 1004.0
Subtracting 3076 from 3459 leaves us with 383.
Include the next digit (7) from the dividend after 383, then repeat: 3837 / 769

Advancing to step 7:
769 can be fit into 3837 4 times, resulting in a remainder of 761.
The next digit of our result is 4. 
Result so far: 10044.0
The remainder is 761 after subtracting 3076 from 3837.
Take the next digit (0) from the dividend and append it to 761, then repeat: 7610 / 769

On to step 8:
769 can be fit into 7610 9 times, resulting in a remainder of 689.
Write down 9 as next digit of the result. 
Result so far: 100449.0
Deduct 6921 from 7610 and we're left with 689.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6890, and continue the process.

On to step 9:
If we divide 6890 by 769, we get 8 and a remainder of 738.
Use 8 as the next digit of our solution. 
Result so far: 100449.8
If we take 6152 away from 6890, we end up with 738.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7380, and continue the process.

Let's proceed to step 10:
769 goes into 7380 9 times with a remainder of 459.
The number 9 becomes the next digit in our result. 
Result so far: 100449.89
Subtracting 6921 from 7380 leaves us with 459.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4590, and continue the process.

Step 11:
If we divide 4590 by 769, we get 5 and a remainder of 745.
Write down 5 as next digit of the result. 
Result so far: 100449.895
If we take 3845 away from 4590, we end up with 745.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7450, and continue the process.

Going ahead to step 12:
If we divide 7450 by 769, we get 9 and a remainder of 529.
Write down 9 as next digit of the result. 
Result so far: 100449.8959
Subtract 6921 from 7450 to get 529.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5290, and continue the process.

Advancing to step 13:
769 can be fit into 5290 6 times, resulting in a remainder of 676.
Put 6 as the next digit of the answer. 
Result so far: 100449.89596
If we subtract 4614 from 5290, we get 676.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6760, and continue the process.

Moving on to step 14:
When dividing 6760 by 769, we get 8 with a remainder of 608.
Record the quotient 8 as the next digit in the result. 
Result so far: 100449.895968
The remainder is 608 after subtracting 6152 from 6760.
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 15:
The number 769 fits into 6080 7 times, leaving a remainder of 697.
Record the quotient 7 as the next digit in the result. 
Result so far: 100449.8959687
Deduct 5383 from 6080 and we're left with 697.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6970, and continue the process.

Going ahead to step 16:
When dividing 6970 by 769, we get 9 with a remainder of 49.
The number 9 becomes the next digit in our result. 
Result so far: 100449.89596879
Subtracting 6921 from 6970 leaves us with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

After the division, we end up with 100449.89596879 and a remainder of 4.9e-08.
