We look at the division of 251583 by 7 
We're looking to find how many times 7 goes into 251583.

Let's proceed to step 1:
7 goes into 2 0 times with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Bring next digit (5) of the dividend behind the 2 and repeat the process: 25 / 7

Advancing to step 2:
The number 7 fits into 25 3 times, leaving a remainder of 4.
The next digit of our result is 3. 
Result so far: 3.0
Deduct 21 from 25 and we're left with 4.
Bring next digit (1) of the dividend behind the 4 and repeat the process: 41 / 7

On to step 3:
The number 7 fits into 41 5 times, leaving a remainder of 6.
The next digit of our result is 5. 
Result so far: 35.0
If we subtract 35 from 41, we get 6.
Include the next digit (5) from the dividend after 6, then repeat: 65 / 7

Advancing to step 4:
If we divide 65 by 7, we get 9 and a remainder of 2.
Record the quotient 9 as the next digit in the result. 
Result so far: 359.0
If we subtract 63 from 65, we get 2.
Grab the next digit (8) from the dividend, add it to 2, then carry on: 28 / 7

Step 5:
7 can be fit into 28 4 times, resulting in a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 3594.0
Subtract 28 from 28 to get 0.
Include the next digit (3) from the dividend after 0, then repeat: 3 / 7

On to step 6:
7 goes into 3 0 times with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 35940.0
Subtracting 0 from 3 leaves us 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 7:
If we divide 30 by 7, we get 4 and a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 35940.4
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.

Let's proceed to step 8:
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: 35940.42
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.

Advancing to step 9:
The number 7 fits into 60 8 times, leaving a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 35940.428
Subtracting 56 from 60 leaves us 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.

Advancing to step 10:
7 can be fit into 40 5 times, resulting in a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 35940.4285
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 11:
7 can be fit into 50 7 times, resulting in a remainder of 1.
Write down 7 as next digit of the result. 
Result so far: 35940.42857
If we take 49 away from 50, we end up 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.

Advancing to step 12:
When dividing 10 by 7, we get 1 with a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 35940.428571
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.

Moving on to step 13:
30 divided by 7 is 4 with a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 35940.4285714
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.

Going ahead to step 14:
The number 7 fits into 20 2 times, leaving a remainder of 6.
The next digit of our result is 2. 
Result so far: 35940.42857142
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.

After the division, we end up with 35940.42857142 and a remainder of 6e-09.
