Let's divide 851453 by 7
Our goal is to divide 851453 by 7.

Step 1:
7 goes into 8 1 times with a remainder of 1.
The next digit of our result is 1. 
Result so far: 1.0
If we take 7 away from 8, we end up with 1.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 7

Let's proceed to step 2:
When dividing 15 by 7, we get 2 with a remainder of 1.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
Subtract 14 from 15 to get 1.
Include the next digit (1) from the dividend after 1, then repeat: 11 / 7

Let's proceed to step 3:
7 can be fit into 11 1 times, resulting in a remainder of 4.
Use 1 as the next digit of our solution. 
Result so far: 121.0
Subtract 7 from 11 to get 4.
Grab the next digit (4) from the dividend, add it to 4, then carry on: 44 / 7

Going ahead to step 4:
44 divided by 7 is 6 with a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 1216.0
The remainder is 2 after subtracting 42 from 44.
Grab the next digit (5) from the dividend, add it to 2, then carry on: 25 / 7

Moving on to step 5:
The number 7 fits into 25 3 times, leaving a remainder of 4.
The next digit of our result is 3. 
Result so far: 12163.0
Deduct 21 from 25 and we're left with 4.
Bring next digit (3) of the dividend behind the 4 and repeat the process: 43 / 7

On to step 6:
7 goes into 43 6 times with a remainder of 1.
Put 6 as the next digit of the answer. 
Result so far: 121636.0
The remainder is 1 after subtracting 42 from 43.
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 7:
The number 7 fits into 10 1 times, leaving a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 121636.1
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 8:
If we divide 30 by 7, we get 4 and a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 121636.14
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.

Advancing to step 9:
20 divided by 7 is 2 with a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 121636.142
Subtracting 14 from 20 leaves us 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.

Let's proceed to step 10:
When dividing 60 by 7, we get 8 with a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 121636.1428
The remainder is 4 after subtracting 56 from 60.
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 11:
7 can be fit into 40 5 times, resulting in a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 121636.14285
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.

On to step 12:
The number 7 fits into 50 7 times, leaving a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 121636.142857
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.

Going ahead to step 13:
7 goes into 10 1 times with a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 121636.1428571
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.

Step 14:
If we divide 30 by 7, we get 4 and a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 121636.14285714
Subtracting 28 from 30 leaves us 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.

Our division results in 121636.14285714 with a remaining 2e-09.
