We divide 643822 by 7
Let's see how many times 7 fits into 643822.

Advancing to step 1:
6 divided by 7 is 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 7

Advancing to step 2:
64 divided by 7 is 9 with a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 9.0
If we subtract 63 from 64, we get 1.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 7

Step 3:
7 can be fit into 13 1 times, resulting in a remainder of 6.
The number 1 becomes the next digit in our result. 
Result so far: 91.0
Subtracting 7 from 13 leaves us with 6.
Fetch the next digit (8) from the dividend, attach it to 6 and continue: 68 / 7

On to step 4:
The number 7 fits into 68 9 times, leaving a remainder of 5.
Record the quotient 9 as the next digit in the result. 
Result so far: 919.0
If we subtract 63 from 68, we get 5.
Include the next digit (2) from the dividend after 5, then repeat: 52 / 7

Moving on to step 5:
If we divide 52 by 7, we get 7 and a remainder of 3.
Record the quotient 7 as the next digit in the result. 
Result so far: 9197.0
Deduct 49 from 52 and we're left with 3.
Fetch the next digit (2) from the dividend, attach it to 3 and continue: 32 / 7

Step 6:
When dividing 32 by 7, we get 4 with a remainder of 4.
Record the quotient 4 as the next digit in the result. 
Result so far: 91974.0
Deduct 28 from 32 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 7:
40 divided by 7 is 5 with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 91974.5
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 8:
The number 7 fits into 50 7 times, leaving a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 91974.57
Subtract 49 from 50 to 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 9:
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: 91974.571
Deduct 7 from 10 and we're left 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.

Advancing to step 10:
7 goes into 30 4 times with a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 91974.5714
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.

Step 11:
7 goes into 20 2 times with a remainder of 6.
The next digit of our result is 2. 
Result so far: 91974.57142
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.

Moving on to step 12:
60 divided by 7 is 8 with a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 91974.571428
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.

Going ahead to step 13:
7 goes into 40 5 times with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 91974.5714285
If we subtract 35 from 40, we 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.

Moving on to step 14:
The number 7 fits into 50 7 times, leaving a remainder of 1.
The next digit of our result is 7. 
Result so far: 91974.57142857
Subtracting 49 from 50 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Our division results in 91974.57142857 with a remaining 1e-09.
