We divide 321857 by 7
We want to figure out the number of times 321857 can be divided by 7.

Moving on to step 1:
The number 7 fits into 3 0 times, leaving a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Include the next digit (2) from the dividend after 3, then repeat: 32 / 7

Moving on to step 2:
When dividing 32 by 7, we get 4 with a remainder of 4.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Deduct 28 from 32 and we're left with 4.
Bring next digit (1) of the dividend behind the 4 and repeat the process: 41 / 7

On to step 3:
7 goes into 41 5 times with a remainder of 6.
Write down 5 as next digit of the result. 
Result so far: 45.0
Deduct 35 from 41 and we're left with 6.
Bring next digit (8) of the dividend behind the 6 and repeat the process: 68 / 7

Let's proceed to step 4:
68 divided by 7 is 9 with a remainder of 5.
Put 9 as the next digit of the answer. 
Result so far: 459.0
Deduct 63 from 68 and we're left with 5.
Bring next digit (5) of the dividend behind the 5 and repeat the process: 55 / 7

Moving on to step 5:
When dividing 55 by 7, we get 7 with a remainder of 6.
Put 7 as the next digit of the answer. 
Result so far: 4597.0
Subtracting 49 from 55 leaves us with 6.
Append the next digit (7) from the dividend to 6 and continue with: 67 / 7

On to step 6:
7 can be fit into 67 9 times, resulting in a remainder of 4.
The next digit of our result is 9. 
Result so far: 45979.0
The remainder is 4 after subtracting 63 from 67.
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 7:
40 divided by 7 is 5 with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 45979.5
Subtracting 35 from 40 leaves us 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.

Going ahead to step 8:
When dividing 50 by 7, we get 7 with a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 45979.57
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.

Step 9:
7 goes into 10 1 times with a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 45979.571
Subtract 7 from 10 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 10:
7 goes into 30 4 times with a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 45979.5714
The remainder is 2 after subtracting 28 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 11:
If we divide 20 by 7, we get 2 and a remainder of 6.
Use 2 as the next digit of our solution. 
Result so far: 45979.57142
Deduct 14 from 20 and we're left 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 12:
7 can be fit into 60 8 times, resulting in a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 45979.571428
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.

Going ahead to step 13:
When dividing 40 by 7, we get 5 with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 45979.5714285
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.

On to step 14:
When dividing 50 by 7, we get 7 with a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 45979.57142857
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.

The final outcome is 45979.57142857, with a leftover of 1e-09.
