123126 ÷ 7 
We're looking to find how many times 7 goes into 123126.

Moving on to step 1:
1 divided by 7 is 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 7

Advancing to step 2:
7 can be fit into 12 1 times, resulting in a remainder of 5.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 7 from 12 and we're left with 5.
Take the next digit (3) from the dividend and append it to 5, then repeat: 53 / 7

Step 3:
When dividing 53 by 7, we get 7 with a remainder of 4.
Use 7 as the next digit of our solution. 
Result so far: 17.0
The remainder is 4 after subtracting 49 from 53.
Include the next digit (1) from the dividend after 4, then repeat: 41 / 7

Let's proceed to step 4:
41 divided by 7 is 5 with a remainder of 6.
The next digit of our result is 5. 
Result so far: 175.0
The remainder is 6 after subtracting 35 from 41.
Fetch the next digit (2) from the dividend, attach it to 6 and continue: 62 / 7

Step 5:
7 can be fit into 62 8 times, resulting in a remainder of 6.
Put 8 as the next digit of the answer. 
Result so far: 1758.0
Subtract 56 from 62 to get 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 7

Advancing to step 6:
66 divided by 7 is 9 with a remainder of 3.
Record the quotient 9 as the next digit in the result. 
Result so far: 17589.0
If we take 63 away from 66, 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.

Advancing to step 7:
The number 7 fits into 30 4 times, leaving a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 17589.4
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.

Advancing to step 8:
20 divided by 7 is 2 with a remainder of 6.
The number 2 becomes the next digit in our result. 
Result so far: 17589.42
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.

Going ahead to step 9:
7 goes into 60 8 times with a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 17589.428
If we take 56 away from 60, we end up 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:
If we divide 40 by 7, we get 5 and a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 17589.4285
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.

Let's proceed to step 11:
50 divided by 7 is 7 with a remainder of 1.
The next digit of our result is 7. 
Result so far: 17589.42857
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.

Moving on to step 12:
If we divide 10 by 7, we get 1 and a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 17589.428571
Subtracting 7 from 10 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.

Going ahead to step 13:
The number 7 fits into 30 4 times, leaving a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 17589.4285714
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.

Step 14:
When dividing 20 by 7, we get 2 with a remainder of 6.
Write down 2 as next digit of the result. 
Result so far: 17589.42857142
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.

After the division, we end up with 17589.42857142 and a remainder of 6e-09.
