We divide 80858873 by 945
We want to divide 80858873 by 945.

Step 1:
The number 945 fits into 8 0 times, leaving a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 945

Moving on to step 2:
The number 945 fits into 80 0 times, leaving a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 80, we end up with 80.
Take the next digit (8) from the dividend and append it to 80, then repeat: 808 / 945

Step 3:
945 goes into 808 0 times with a remainder of 808.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 808 after subtracting 0 from 808.
Append the next digit (5) from the dividend to 808 and continue with: 8085 / 945

Advancing to step 4:
If we divide 8085 by 945, we get 8 and a remainder of 525.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
The remainder is 525 after subtracting 7560 from 8085.
Fetch the next digit (8) from the dividend, attach it to 525 and continue: 5258 / 945

Moving on to step 5:
5258 divided by 945 is 5 with a remainder of 533.
Record the quotient 5 as the next digit in the result. 
Result so far: 85.0
The remainder is 533 after subtracting 4725 from 5258.
Grab the next digit (8) from the dividend, add it to 533, then carry on: 5338 / 945

Going ahead to step 6:
When dividing 5338 by 945, we get 5 with a remainder of 613.
The number 5 becomes the next digit in our result. 
Result so far: 855.0
Deduct 4725 from 5338 and we're left with 613.
Fetch the next digit (7) from the dividend, attach it to 613 and continue: 6137 / 945

Let's proceed to step 7:
945 can be fit into 6137 6 times, resulting in a remainder of 467.
Put 6 as the next digit of the answer. 
Result so far: 8556.0
The remainder is 467 after subtracting 5670 from 6137.
Grab the next digit (3) from the dividend, add it to 467, then carry on: 4673 / 945

Advancing to step 8:
945 goes into 4673 4 times with a remainder of 893.
Put 4 as the next digit of the answer. 
Result so far: 85564.0
Subtracting 3780 from 4673 leaves us with 893.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8930, and continue the process.

Step 9:
The number 945 fits into 8930 9 times, leaving a remainder of 425.
The number 9 becomes the next digit in our result. 
Result so far: 85564.9
If we subtract 8505 from 8930, we get 425.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4250, and continue the process.

Advancing to step 10:
If we divide 4250 by 945, we get 4 and a remainder of 470.
The number 4 becomes the next digit in our result. 
Result so far: 85564.94
Subtracting 3780 from 4250 leaves us with 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4700, and continue the process.

On to step 11:
When dividing 4700 by 945, we get 4 with a remainder of 920.
Use 4 as the next digit of our solution. 
Result so far: 85564.944
If we subtract 3780 from 4700, we get 920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9200, and continue the process.

The quotient of the division is 85564.944, and the remainder is 0.092.
