We divide 126147 by 7
We want to figure out the number of times 126147 can be divided by 7.

Going ahead to step 1:
When dividing 1 by 7, we get 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 7

On to step 2:
7 goes into 12 1 times with a remainder of 5.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 5 after subtracting 7 from 12.
Take the next digit (6) from the dividend and append it to 5, then repeat: 56 / 7

Advancing to step 3:
7 can be fit into 56 8 times, resulting in a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 18.0
Subtract 56 from 56 to get 0.
Append the next digit (1) from the dividend to 0 and continue with: 1 / 7

Step 4:
The number 7 fits into 1 0 times, leaving a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 180.0
If we subtract 0 from 1, we get 1.
Grab the next digit (4) from the dividend, add it to 1, then carry on: 14 / 7

Let's proceed to step 5:
If we divide 14 by 7, we get 2 and a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 1802.0
Subtract 14 from 14 to get 0.
Append the next digit (7) from the dividend to 0 and continue with: 7 / 7

Advancing to step 6:
If we divide 7 by 7, we get 1 and a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 18021.0
Subtracting 7 from 7 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 7:
When dividing 0 by 7, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 18021.0
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 8:
0 divided by 7 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 18021.0
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 18021.0 and a remainder of 0.0.
