78590113 divided by 945 
We want to figure out the number of times 78590113 can be divided by 945.

On to step 1:
945 can be fit into 7 0 times, resulting in a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 945

On to step 2:
945 goes into 78 0 times with a remainder of 78.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 78 and we're left with 78.
Take the next digit (5) from the dividend and append it to 78, then repeat: 785 / 945

Advancing to step 3:
If we divide 785 by 945, we get 0 and a remainder of 785.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 785 and we're left with 785.
Append the next digit (9) from the dividend to 785 and continue with: 7859 / 945

Moving on to step 4:
7859 divided by 945 is 8 with a remainder of 299.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
If we take 7560 away from 7859, we end up with 299.
Take the next digit (0) from the dividend and append it to 299, then repeat: 2990 / 945

Going ahead to step 5:
If we divide 2990 by 945, we get 3 and a remainder of 155.
The next digit of our result is 3. 
Result so far: 83.0
Deduct 2835 from 2990 and we're left with 155.
Append the next digit (1) from the dividend to 155 and continue with: 1551 / 945

Moving on to step 6:
When dividing 1551 by 945, we get 1 with a remainder of 606.
Record the quotient 1 as the next digit in the result. 
Result so far: 831.0
Subtracting 945 from 1551 leaves us with 606.
Fetch the next digit (1) from the dividend, attach it to 606 and continue: 6061 / 945

On to step 7:
945 goes into 6061 6 times with a remainder of 391.
Record the quotient 6 as the next digit in the result. 
Result so far: 8316.0
Deduct 5670 from 6061 and we're left with 391.
Append the next digit (3) from the dividend to 391 and continue with: 3913 / 945

Advancing to step 8:
The number 945 fits into 3913 4 times, leaving a remainder of 133.
Use 4 as the next digit of our solution. 
Result so far: 83164.0
Subtracting 3780 from 3913 leaves us with 133.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1330, and continue the process.

On to step 9:
If we divide 1330 by 945, we get 1 and a remainder of 385.
Write down 1 as next digit of the result. 
Result so far: 83164.1
The remainder is 385 after subtracting 945 from 1330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3850, and continue the process.

Let's proceed to step 10:
945 goes into 3850 4 times with a remainder of 70.
Put 4 as the next digit of the answer. 
Result so far: 83164.14
Subtract 3780 from 3850 to 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.

On to step 11:
The number 945 fits into 700 0 times, leaving a remainder of 700.
The next digit of our result is 0. 
Result so far: 83164.14
The remainder is 700 after subtracting 0 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

Advancing to step 12:
945 goes into 7000 7 times with a remainder of 385.
The next digit of our result is 7. 
Result so far: 83164.1407
Deduct 6615 from 7000 and we're left with 385.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3850, and continue the process.

Advancing to step 13:
If we divide 3850 by 945, we get 4 and a remainder of 70.
Put 4 as the next digit of the answer. 
Result so far: 83164.14074
The remainder is 70 after subtracting 3780 from 3850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Moving on to step 14:
945 can be fit into 700 0 times, resulting in a remainder of 700.
The number 0 becomes the next digit in our result. 
Result so far: 83164.14074
If we subtract 0 from 700, we get 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

Let's proceed to step 15:
7000 divided by 945 is 7 with a remainder of 385.
Use 7 as the next digit of our solution. 
Result so far: 83164.1407407
Deduct 6615 from 7000 and we're left with 385.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3850, and continue the process.

Step 16:
3850 divided by 945 is 4 with a remainder of 70.
Put 4 as the next digit of the answer. 
Result so far: 83164.14074074
Deduct 3780 from 3850 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Our division results in 83164.14074074 with a remaining 7e-08.
