3830991 ÷ 231 
We want to figure out the number of times 3830991 can be divided by 231.

Moving on to step 1:
When dividing 3 by 231, we get 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Include the next digit (8) from the dividend after 3, then repeat: 38 / 231

Going ahead to step 2:
If we divide 38 by 231, we get 0 and a remainder of 38.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 38 and we're left with 38.
Take the next digit (3) from the dividend and append it to 38, then repeat: 383 / 231

Moving on to step 3:
When dividing 383 by 231, we get 1 with a remainder of 152.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 152 after subtracting 231 from 383.
Bring next digit (0) of the dividend behind the 152 and repeat the process: 1520 / 231

Step 4:
231 goes into 1520 6 times with a remainder of 134.
The number 6 becomes the next digit in our result. 
Result so far: 16.0
The remainder is 134 after subtracting 1386 from 1520.
Grab the next digit (9) from the dividend, add it to 134, then carry on: 1349 / 231

Step 5:
If we divide 1349 by 231, we get 5 and a remainder of 194.
Record the quotient 5 as the next digit in the result. 
Result so far: 165.0
Deduct 1155 from 1349 and we're left with 194.
Append the next digit (9) from the dividend to 194 and continue with: 1949 / 231

Let's proceed to step 6:
231 goes into 1949 8 times with a remainder of 101.
The number 8 becomes the next digit in our result. 
Result so far: 1658.0
If we subtract 1848 from 1949, we get 101.
Bring next digit (1) of the dividend behind the 101 and repeat the process: 1011 / 231

Advancing to step 7:
231 goes into 1011 4 times with a remainder of 87.
The number 4 becomes the next digit in our result. 
Result so far: 16584.0
Deduct 924 from 1011 and we're left with 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Advancing to step 8:
231 can be fit into 870 3 times, resulting in a remainder of 177.
Write down 3 as next digit of the result. 
Result so far: 16584.3
Subtract 693 from 870 to get 177.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1770, and continue the process.

Step 9:
1770 divided by 231 is 7 with a remainder of 153.
Write down 7 as next digit of the result. 
Result so far: 16584.37
The remainder is 153 after subtracting 1617 from 1770.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1530, and continue the process.

On to step 10:
231 goes into 1530 6 times with a remainder of 144.
Use 6 as the next digit of our solution. 
Result so far: 16584.376
If we take 1386 away from 1530, we end up with 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Step 11:
When dividing 1440 by 231, we get 6 with a remainder of 54.
Use 6 as the next digit of our solution. 
Result so far: 16584.3766
Deduct 1386 from 1440 and we're left with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

The quotient of the division is 16584.3766, and the remainder is 0.00054.
