30689835 ÷ 831 
We want to divide 30689835 by 831.

Let's proceed to step 1:
831 goes into 3 0 times with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 831

Advancing to step 2:
831 goes into 30 0 times with a remainder of 30.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 30, we get 30.
Fetch the next digit (6) from the dividend, attach it to 30 and continue: 306 / 831

Advancing to step 3:
831 can be fit into 306 0 times, resulting in a remainder of 306.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 306 to get 306.
Bring next digit (8) of the dividend behind the 306 and repeat the process: 3068 / 831

Moving on to step 4:
The number 831 fits into 3068 3 times, leaving a remainder of 575.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we subtract 2493 from 3068, we get 575.
Include the next digit (9) from the dividend after 575, then repeat: 5759 / 831

Going ahead to step 5:
If we divide 5759 by 831, we get 6 and a remainder of 773.
The number 6 becomes the next digit in our result. 
Result so far: 36.0
Deduct 4986 from 5759 and we're left with 773.
Grab the next digit (8) from the dividend, add it to 773, then carry on: 7738 / 831

Step 6:
If we divide 7738 by 831, we get 9 and a remainder of 259.
The number 9 becomes the next digit in our result. 
Result so far: 369.0
Subtract 7479 from 7738 to get 259.
Include the next digit (3) from the dividend after 259, then repeat: 2593 / 831

Going ahead to step 7:
When dividing 2593 by 831, we get 3 with a remainder of 100.
Put 3 as the next digit of the answer. 
Result so far: 3693.0
If we take 2493 away from 2593, we end up with 100.
Bring next digit (5) of the dividend behind the 100 and repeat the process: 1005 / 831

Step 8:
831 goes into 1005 1 times with a remainder of 174.
Use 1 as the next digit of our solution. 
Result so far: 36931.0
Subtracting 831 from 1005 leaves us with 174.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

Let's proceed to step 9:
831 can be fit into 1740 2 times, resulting in a remainder of 78.
Write down 2 as next digit of the result. 
Result so far: 36931.2
If we take 1662 away from 1740, we end up with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Going ahead to step 10:
When dividing 780 by 831, we get 0 with a remainder of 780.
Write down 0 as next digit of the result. 
Result so far: 36931.2
Deduct 0 from 780 and we're left with 780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7800, and continue the process.

Let's proceed to step 11:
831 can be fit into 7800 9 times, resulting in a remainder of 321.
Use 9 as the next digit of our solution. 
Result so far: 36931.209
Deduct 7479 from 7800 and we're left with 321.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3210, and continue the process.

On to step 12:
The number 831 fits into 3210 3 times, leaving a remainder of 717.
Record the quotient 3 as the next digit in the result. 
Result so far: 36931.2093
Subtract 2493 from 3210 to get 717.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7170, and continue the process.

Let's proceed to step 13:
The number 831 fits into 7170 8 times, leaving a remainder of 522.
Put 8 as the next digit of the answer. 
Result so far: 36931.20938
Subtract 6648 from 7170 to get 522.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5220, and continue the process.

On to step 14:
The number 831 fits into 5220 6 times, leaving a remainder of 234.
Use 6 as the next digit of our solution. 
Result so far: 36931.209386
Subtract 4986 from 5220 to get 234.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2340, and continue the process.

Moving on to step 15:
The number 831 fits into 2340 2 times, leaving a remainder of 678.
The number 2 becomes the next digit in our result. 
Result so far: 36931.2093862
The remainder is 678 after subtracting 1662 from 2340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6780, and continue the process.

On to step 16:
831 goes into 6780 8 times with a remainder of 132.
Put 8 as the next digit of the answer. 
Result so far: 36931.20938628
Deduct 6648 from 6780 and we're left with 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

After the division, we end up with 36931.20938628 and a remainder of 1.32e-07.
