We look at the division of 77561730 by 945 
We want to figure out the number of times 77561730 can be divided by 945.

Going ahead to step 1:
When dividing 7 by 945, we get 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Bring next digit (7) of the dividend behind the 7 and repeat the process: 77 / 945

Advancing to step 2:
When dividing 77 by 945, we get 0 with a remainder of 77.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 77 and we're left with 77.
Append the next digit (5) from the dividend to 77 and continue with: 775 / 945

Advancing to step 3:
If we divide 775 by 945, we get 0 and a remainder of 775.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 775 and we're left with 775.
Include the next digit (6) from the dividend after 775, then repeat: 7756 / 945

On to step 4:
When dividing 7756 by 945, we get 8 with a remainder of 196.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
If we subtract 7560 from 7756, we get 196.
Fetch the next digit (1) from the dividend, attach it to 196 and continue: 1961 / 945

On to step 5:
1961 divided by 945 is 2 with a remainder of 71.
Put 2 as the next digit of the answer. 
Result so far: 82.0
If we take 1890 away from 1961, we end up with 71.
Bring next digit (7) of the dividend behind the 71 and repeat the process: 717 / 945

Going ahead to step 6:
945 goes into 717 0 times with a remainder of 717.
Record the quotient 0 as the next digit in the result. 
Result so far: 820.0
Subtracting 0 from 717 leaves us with 717.
Bring next digit (3) of the dividend behind the 717 and repeat the process: 7173 / 945

Moving on to step 7:
When dividing 7173 by 945, we get 7 with a remainder of 558.
Write down 7 as next digit of the result. 
Result so far: 8207.0
If we subtract 6615 from 7173, we get 558.
Take the next digit (0) from the dividend and append it to 558, then repeat: 5580 / 945

Moving on to step 8:
If we divide 5580 by 945, we get 5 and a remainder of 855.
Record the quotient 5 as the next digit in the result. 
Result so far: 82075.0
Subtract 4725 from 5580 to get 855.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8550, and continue the process.

On to step 9:
If we divide 8550 by 945, we get 9 and a remainder of 45.
Put 9 as the next digit of the answer. 
Result so far: 82075.9
Subtracting 8505 from 8550 leaves us with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Let's proceed to step 10:
If we divide 450 by 945, we get 0 and a remainder of 450.
Record the quotient 0 as the next digit in the result. 
Result so far: 82075.9
If we subtract 0 from 450, we get 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

Advancing to step 11:
945 can be fit into 4500 4 times, resulting in a remainder of 720.
Put 4 as the next digit of the answer. 
Result so far: 82075.904
Subtracting 3780 from 4500 leaves us with 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7200, and continue the process.

Advancing to step 12:
When dividing 7200 by 945, we get 7 with a remainder of 585.
The next digit of our result is 7. 
Result so far: 82075.9047
If we subtract 6615 from 7200, we get 585.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5850, and continue the process.

Let's proceed to step 13:
When dividing 5850 by 945, we get 6 with a remainder of 180.
The number 6 becomes the next digit in our result. 
Result so far: 82075.90476
Subtracting 5670 from 5850 leaves us with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Step 14:
When dividing 1800 by 945, we get 1 with a remainder of 855.
The next digit of our result is 1. 
Result so far: 82075.904761
If we take 945 away from 1800, we end up with 855.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8550, and continue the process.

Going ahead to step 15:
945 goes into 8550 9 times with a remainder of 45.
Put 9 as the next digit of the answer. 
Result so far: 82075.9047619
Deduct 8505 from 8550 and we're left with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 16:
945 can be fit into 450 0 times, resulting in a remainder of 450.
Use 0 as the next digit of our solution. 
Result so far: 82075.9047619
If we subtract 0 from 450, we get 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

The final outcome is 82075.9047619, with a leftover of 4.5e-07.
