We divide 643654 by 7
Let's see how many times 7 fits into 643654.

Going ahead to step 1:
7 can be fit into 6 0 times, resulting in a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 7

Step 2:
7 goes into 64 9 times with a remainder of 1.
The next digit of our result is 9. 
Result so far: 9.0
If we take 63 away from 64, we end up with 1.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 7

Going ahead to step 3:
7 goes into 13 1 times with a remainder of 6.
Put 1 as the next digit of the answer. 
Result so far: 91.0
Subtracting 7 from 13 leaves us with 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 7

Let's proceed to step 4:
The number 7 fits into 66 9 times, leaving a remainder of 3.
The next digit of our result is 9. 
Result so far: 919.0
If we subtract 63 from 66, we get 3.
Grab the next digit (5) from the dividend, add it to 3, then carry on: 35 / 7

Advancing to step 5:
7 can be fit into 35 5 times, resulting in a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 9195.0
Subtract 35 from 35 to get 0.
Fetch the next digit (4) from the dividend, attach it to 0 and continue: 4 / 7

Let's proceed to step 6:
7 goes into 4 0 times with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 91950.0
The remainder is 4 after subtracting 0 from 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: 91950.5
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.

Advancing to step 8:
If we divide 50 by 7, we get 7 and a remainder of 1.
Use 7 as the next digit of our solution. 
Result so far: 91950.57
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.

On to step 9:
7 can be fit into 10 1 times, resulting in a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 91950.571
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:
When dividing 30 by 7, we get 4 with a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 91950.5714
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.

Step 11:
When dividing 20 by 7, we get 2 with a remainder of 6.
The next digit of our result is 2. 
Result so far: 91950.57142
The remainder is 6 after subtracting 14 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 12:
7 goes into 60 8 times with a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 91950.571428
Subtract 56 from 60 to 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.

Let's proceed to step 13:
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: 91950.5714285
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.

Step 14:
7 can be fit into 50 7 times, resulting in a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 91950.57142857
Deduct 49 from 50 and we're left 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 91950.57142857 with a remaining 1e-09.
