We're dividing 70809783 by 831 
We want to figure out the number of times 70809783 can be divided by 831.

Advancing to step 1:
831 goes into 7 0 times with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Take the next digit (0) from the dividend and append it to 7, then repeat: 70 / 831

On to step 2:
70 divided by 831 is 0 with a remainder of 70.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 70, we get 70.
Fetch the next digit (8) from the dividend, attach it to 70 and continue: 708 / 831

Let's proceed to step 3:
If we divide 708 by 831, we get 0 and a remainder of 708.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 708, we get 708.
Fetch the next digit (0) from the dividend, attach it to 708 and continue: 7080 / 831

Let's proceed to step 4:
If we divide 7080 by 831, we get 8 and a remainder of 432.
Put 8 as the next digit of the answer. 
Result so far: 8.0
If we subtract 6648 from 7080, we get 432.
Fetch the next digit (9) from the dividend, attach it to 432 and continue: 4329 / 831

On to step 5:
4329 divided by 831 is 5 with a remainder of 174.
Write down 5 as next digit of the result. 
Result so far: 85.0
The remainder is 174 after subtracting 4155 from 4329.
Bring next digit (7) of the dividend behind the 174 and repeat the process: 1747 / 831

Moving on to step 6:
The number 831 fits into 1747 2 times, leaving a remainder of 85.
Use 2 as the next digit of our solution. 
Result so far: 852.0
Deduct 1662 from 1747 and we're left with 85.
Fetch the next digit (8) from the dividend, attach it to 85 and continue: 858 / 831

Let's proceed to step 7:
831 goes into 858 1 times with a remainder of 27.
The number 1 becomes the next digit in our result. 
Result so far: 8521.0
Subtract 831 from 858 to get 27.
Grab the next digit (3) from the dividend, add it to 27, then carry on: 273 / 831

Moving on to step 8:
If we divide 273 by 831, we get 0 and a remainder of 273.
Record the quotient 0 as the next digit in the result. 
Result so far: 85210.0
Deduct 0 from 273 and we're left with 273.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2730, and continue the process.

Let's proceed to step 9:
When dividing 2730 by 831, we get 3 with a remainder of 237.
Put 3 as the next digit of the answer. 
Result so far: 85210.3
Subtracting 2493 from 2730 leaves us with 237.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2370, and continue the process.

On to step 10:
If we divide 2370 by 831, we get 2 and a remainder of 708.
Write down 2 as next digit of the result. 
Result so far: 85210.32
Subtracting 1662 from 2370 leaves us with 708.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7080, and continue the process.

On to step 11:
7080 divided by 831 is 8 with a remainder of 432.
The number 8 becomes the next digit in our result. 
Result so far: 85210.328
If we take 6648 away from 7080, we end up with 432.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4320, and continue the process.

On to step 12:
If we divide 4320 by 831, we get 5 and a remainder of 165.
The number 5 becomes the next digit in our result. 
Result so far: 85210.3285
Subtracting 4155 from 4320 leaves us with 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

On to step 13:
If we divide 1650 by 831, we get 1 and a remainder of 819.
The next digit of our result is 1. 
Result so far: 85210.32851
The remainder is 819 after subtracting 831 from 1650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8190, and continue the process.

Step 14:
The number 831 fits into 8190 9 times, leaving a remainder of 711.
Put 9 as the next digit of the answer. 
Result so far: 85210.328519
Deduct 7479 from 8190 and we're left with 711.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7110, and continue the process.

Moving on to step 15:
7110 divided by 831 is 8 with a remainder of 462.
The number 8 becomes the next digit in our result. 
Result so far: 85210.3285198
If we subtract 6648 from 7110, we get 462.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4620, and continue the process.

Moving on to step 16:
When dividing 4620 by 831, we get 5 with a remainder of 465.
The number 5 becomes the next digit in our result. 
Result so far: 85210.32851985
If we subtract 4155 from 4620, we get 465.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4650, and continue the process.

Our division results in 85210.32851985 with a remaining 4.65e-07.
