We're dividing 77563872 by 945 
We want to figure out the number of times 77563872 can be divided by 945.

Moving on to step 1:
945 goes into 7 0 times with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Fetch the next digit (7) from the dividend, attach it to 7 and continue: 77 / 945

Going ahead to step 2:
If we divide 77 by 945, we get 0 and a remainder of 77.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 77, we get 77.
Take the next digit (5) from the dividend and append it to 77, then repeat: 775 / 945

Step 3:
When dividing 775 by 945, we get 0 with a remainder of 775.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 775, we end up with 775.
Take the next digit (6) from the dividend and append it to 775, then repeat: 7756 / 945

Moving on to step 4:
945 goes into 7756 8 times with a remainder of 196.
Write down 8 as next digit of the result. 
Result so far: 8.0
Subtract 7560 from 7756 to get 196.
Bring next digit (3) of the dividend behind the 196 and repeat the process: 1963 / 945

Let's proceed to step 5:
945 can be fit into 1963 2 times, resulting in a remainder of 73.
Use 2 as the next digit of our solution. 
Result so far: 82.0
The remainder is 73 after subtracting 1890 from 1963.
Take the next digit (8) from the dividend and append it to 73, then repeat: 738 / 945

Let's proceed to step 6:
945 can be fit into 738 0 times, resulting in a remainder of 738.
Put 0 as the next digit of the answer. 
Result so far: 820.0
Subtracting 0 from 738 leaves us with 738.
Bring next digit (7) of the dividend behind the 738 and repeat the process: 7387 / 945

On to step 7:
The number 945 fits into 7387 7 times, leaving a remainder of 772.
The number 7 becomes the next digit in our result. 
Result so far: 8207.0
If we subtract 6615 from 7387, we get 772.
Include the next digit (2) from the dividend after 772, then repeat: 7722 / 945

Step 8:
When dividing 7722 by 945, we get 8 with a remainder of 162.
Put 8 as the next digit of the answer. 
Result so far: 82078.0
If we take 7560 away from 7722, we end up with 162.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1620, and continue the process.

On to step 9:
945 can be fit into 1620 1 times, resulting in a remainder of 675.
Put 1 as the next digit of the answer. 
Result so far: 82078.1
Deduct 945 from 1620 and we're left with 675.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6750, and continue the process.

Let's proceed to step 10:
When dividing 6750 by 945, we get 7 with a remainder of 135.
Record the quotient 7 as the next digit in the result. 
Result so far: 82078.17
If we subtract 6615 from 6750, we get 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Advancing to step 11:
1350 divided by 945 is 1 with a remainder of 405.
Write down 1 as next digit of the result. 
Result so far: 82078.171
The remainder is 405 after subtracting 945 from 1350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4050, and continue the process.

Let's proceed to step 12:
4050 divided by 945 is 4 with a remainder of 270.
Use 4 as the next digit of our solution. 
Result so far: 82078.1714
Subtract 3780 from 4050 to get 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Step 13:
If we divide 2700 by 945, we get 2 and a remainder of 810.
Write down 2 as next digit of the result. 
Result so far: 82078.17142
Subtracting 1890 from 2700 leaves us with 810.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8100, and continue the process.

On to step 14:
945 goes into 8100 8 times with a remainder of 540.
Use 8 as the next digit of our solution. 
Result so far: 82078.171428
Subtract 7560 from 8100 to get 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

Advancing to step 15:
When dividing 5400 by 945, we get 5 with a remainder of 675.
Record the quotient 5 as the next digit in the result. 
Result so far: 82078.1714285
The remainder is 675 after subtracting 4725 from 5400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6750, and continue the process.

Step 16:
The number 945 fits into 6750 7 times, leaving a remainder of 135.
Write down 7 as next digit of the result. 
Result so far: 82078.17142857
Deduct 6615 from 6750 and we're left with 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

The final result is 82078.17142857 with a remainder of 1.35e-07.
