821389 divided by 7 
Let's see how many times 7 fits into 821389.

Let's proceed to step 1:
When dividing 8 by 7, we get 1 with a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 7 away from 8, we end up with 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 7

Let's proceed to step 2:
The number 7 fits into 12 1 times, leaving a remainder of 5.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
If we take 7 away from 12, we end up with 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 7

Let's proceed to step 3:
The number 7 fits into 51 7 times, leaving a remainder of 2.
Record the quotient 7 as the next digit in the result. 
Result so far: 117.0
If we take 49 away from 51, we end up with 2.
Grab the next digit (3) from the dividend, add it to 2, then carry on: 23 / 7

Going ahead to step 4:
The number 7 fits into 23 3 times, leaving a remainder of 2.
Record the quotient 3 as the next digit in the result. 
Result so far: 1173.0
The remainder is 2 after subtracting 21 from 23.
Grab the next digit (8) from the dividend, add it to 2, then carry on: 28 / 7

Going ahead to step 5:
If we divide 28 by 7, we get 4 and a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 11734.0
The remainder is 0 after subtracting 28 from 28.
Take the next digit (9) from the dividend and append it to 0, then repeat: 9 / 7

On to step 6:
When dividing 9 by 7, we get 1 with a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 117341.0
Deduct 7 from 9 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 7:
When dividing 20 by 7, we get 2 with a remainder of 6.
The next digit of our result is 2. 
Result so far: 117341.2
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 8:
60 divided by 7 is 8 with a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 117341.28
Deduct 56 from 60 and we're left 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 9:
If we divide 40 by 7, we get 5 and a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 117341.285
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.

Let's proceed to step 10:
7 can be fit into 50 7 times, resulting in a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 117341.2857
If we subtract 49 from 50, we get 1.
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 11:
The number 7 fits into 10 1 times, leaving a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 117341.28571
If we take 7 away from 10, we end up 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.

On to step 12:
If we divide 30 by 7, we get 4 and a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 117341.285714
Subtract 28 from 30 to 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 13:
7 goes into 20 2 times with a remainder of 6.
Write down 2 as next digit of the result. 
Result so far: 117341.2857142
If we subtract 14 from 20, we get 6.
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 14:
7 goes into 60 8 times with a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 117341.28571428
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.

The final outcome is 117341.28571428, with a leftover of 4e-09.
