We look at the division of 641768 by 7 
We want to figure out the number of times 641768 can be divided by 7.

On to step 1:
If we divide 6 by 7, we get 0 and a remainder of 6.
Write down 0 as next digit of the result. 
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

On to step 2:
7 goes into 64 9 times with a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
The remainder is 1 after subtracting 63 from 64.
Fetch the next digit (1) from the dividend, attach it to 1 and continue: 11 / 7

On to step 3:
7 can be fit into 11 1 times, resulting in a remainder of 4.
The number 1 becomes the next digit in our result. 
Result so far: 91.0
If we take 7 away from 11, we end up with 4.
Take the next digit (7) from the dividend and append it to 4, then repeat: 47 / 7

On to step 4:
7 can be fit into 47 6 times, resulting in a remainder of 5.
Put 6 as the next digit of the answer. 
Result so far: 916.0
Deduct 42 from 47 and we're left with 5.
Grab the next digit (6) from the dividend, add it to 5, then carry on: 56 / 7

Let's proceed to step 5:
56 divided by 7 is 8 with a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 9168.0
Subtract 56 from 56 to get 0.
Take the next digit (8) from the dividend and append it to 0, then repeat: 8 / 7

On to step 6:
If we divide 8 by 7, we get 1 and a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 91681.0
Deduct 7 from 8 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.

Let's proceed to step 7:
10 divided by 7 is 1 with a remainder of 3.
The next digit of our result is 1. 
Result so far: 91681.1
The remainder is 3 after subtracting 7 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 8:
7 can be fit into 30 4 times, resulting in a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 91681.14
Deduct 28 from 30 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.

On to step 9:
20 divided by 7 is 2 with a remainder of 6.
Record the quotient 2 as the next digit in the result. 
Result so far: 91681.142
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.

Let's proceed to step 10:
60 divided by 7 is 8 with a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 91681.1428
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 11:
If we divide 40 by 7, we get 5 and a remainder of 5.
The next digit of our result is 5. 
Result so far: 91681.14285
If we take 35 away from 40, we end up 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.

Advancing to step 12:
When dividing 50 by 7, we get 7 with a remainder of 1.
Use 7 as the next digit of our solution. 
Result so far: 91681.142857
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.

Going ahead to step 13:
The number 7 fits into 10 1 times, leaving a remainder of 3.
The next digit of our result is 1. 
Result so far: 91681.1428571
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 14:
The number 7 fits into 30 4 times, leaving a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 91681.14285714
Deduct 28 from 30 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.

The final outcome is 91681.14285714, with a leftover of 2e-09.
