We look at the division of 126376 by 7 
We want to divide 126376 by 7.

Advancing to step 1:
When dividing 1 by 7, we get 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 7

Step 2:
7 goes into 12 1 times with a remainder of 5.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 5 after subtracting 7 from 12.
Bring next digit (6) of the dividend behind the 5 and repeat the process: 56 / 7

Step 3:
When dividing 56 by 7, we get 8 with a remainder of 0.
The next digit of our result is 8. 
Result so far: 18.0
Subtracting 56 from 56 leaves us with 0.
Append the next digit (3) from the dividend to 0 and continue with: 3 / 7

Step 4:
If we divide 3 by 7, we get 0 and a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 180.0
If we subtract 0 from 3, we get 3.
Bring next digit (7) of the dividend behind the 3 and repeat the process: 37 / 7

Let's proceed to step 5:
The number 7 fits into 37 5 times, leaving a remainder of 2.
Write down 5 as next digit of the result. 
Result so far: 1805.0
The remainder is 2 after subtracting 35 from 37.
Append the next digit (6) from the dividend to 2 and continue with: 26 / 7

Advancing to step 6:
The number 7 fits into 26 3 times, leaving a remainder of 5.
Write down 3 as next digit of the result. 
Result so far: 18053.0
If we take 21 away from 26, 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.

Moving on to step 7:
If we divide 50 by 7, we get 7 and a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 18053.7
If we subtract 49 from 50, we 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.

Moving on to step 8:
If we divide 10 by 7, we get 1 and a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 18053.71
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.

Step 9:
The number 7 fits into 30 4 times, leaving a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 18053.714
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.

Advancing to step 10:
7 can be fit into 20 2 times, resulting in a remainder of 6.
The number 2 becomes the next digit in our result. 
Result so far: 18053.7142
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.

Let's proceed to step 11:
When dividing 60 by 7, we get 8 with a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 18053.71428
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.

Moving on to step 12:
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: 18053.714285
Deduct 35 from 40 and we're left 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.

On to step 13:
50 divided by 7 is 7 with a remainder of 1.
The next digit of our result is 7. 
Result so far: 18053.7142857
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.

Going ahead to step 14:
If we divide 10 by 7, we get 1 and a remainder of 3.
The next digit of our result is 1. 
Result so far: 18053.71428571
If we subtract 7 from 10, we 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.

The quotient of the division is 18053.71428571, and the remainder is 3e-09.
