Let's divide 321831 by 7
Our goal is to divide 321831 by 7.

On to step 1:
3 divided by 7 is 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Bring next digit (2) of the dividend behind the 3 and repeat the process: 32 / 7

On to step 2:
7 goes into 32 4 times with a remainder of 4.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtract 28 from 32 to get 4.
Take the next digit (1) from the dividend and append it to 4, then repeat: 41 / 7

Going ahead to step 3:
The number 7 fits into 41 5 times, leaving a remainder of 6.
Put 5 as the next digit of the answer. 
Result so far: 45.0
Deduct 35 from 41 and we're left with 6.
Grab the next digit (8) from the dividend, add it to 6, then carry on: 68 / 7

Going ahead to step 4:
68 divided by 7 is 9 with a remainder of 5.
Record the quotient 9 as the next digit in the result. 
Result so far: 459.0
Subtracting 63 from 68 leaves us with 5.
Take the next digit (3) from the dividend and append it to 5, then repeat: 53 / 7

Step 5:
The number 7 fits into 53 7 times, leaving a remainder of 4.
Record the quotient 7 as the next digit in the result. 
Result so far: 4597.0
If we subtract 49 from 53, we get 4.
Fetch the next digit (1) from the dividend, attach it to 4 and continue: 41 / 7

Step 6:
If we divide 41 by 7, we get 5 and a remainder of 6.
Record the quotient 5 as the next digit in the result. 
Result so far: 45975.0
The remainder is 6 after subtracting 35 from 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 7:
60 divided by 7 is 8 with a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 45975.8
If we subtract 56 from 60, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 8:
If we divide 40 by 7, we get 5 and a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 45975.85
Deduct 35 from 40 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 9:
50 divided by 7 is 7 with a remainder of 1.
The next digit of our result is 7. 
Result so far: 45975.857
The remainder is 1 after subtracting 49 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 10:
The number 7 fits into 10 1 times, leaving a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 45975.8571
Subtracting 7 from 10 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 11:
When dividing 30 by 7, we get 4 with a remainder of 2.
The next digit of our result is 4. 
Result so far: 45975.85714
If we subtract 28 from 30, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 12:
7 goes into 20 2 times with a remainder of 6.
The next digit of our result is 2. 
Result so far: 45975.857142
If we take 14 away from 20, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 13:
The number 7 fits into 60 8 times, leaving a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 45975.8571428
Subtracting 56 from 60 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 14:
40 divided by 7 is 5 with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 45975.85714285
Subtract 35 from 40 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

After the division, we end up with 45975.85714285 and a remainder of 5e-09.
