124478 divided by 7 
We're looking to find how many times 7 goes into 124478.

Advancing to step 1:
If we divide 1 by 7, we get 0 and a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 7

On to step 2:
If we divide 12 by 7, we get 1 and 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.
Bring next digit (4) of the dividend behind the 5 and repeat the process: 54 / 7

Let's proceed to step 3:
7 can be fit into 54 7 times, resulting in a remainder of 5.
Put 7 as the next digit of the answer. 
Result so far: 17.0
Subtracting 49 from 54 leaves us with 5.
Append the next digit (4) from the dividend to 5 and continue with: 54 / 7

Step 4:
If we divide 54 by 7, we get 7 and a remainder of 5.
Write down 7 as next digit of the result. 
Result so far: 177.0
If we subtract 49 from 54, we get 5.
Fetch the next digit (7) from the dividend, attach it to 5 and continue: 57 / 7

On to step 5:
7 goes into 57 8 times with a remainder of 1.
Write down 8 as next digit of the result. 
Result so far: 1778.0
If we take 56 away from 57, we end up with 1.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 7

Advancing to step 6:
If we divide 18 by 7, we get 2 and a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 17782.0
The remainder is 4 after subtracting 14 from 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 7:
When dividing 40 by 7, we get 5 with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 17782.5
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.

Step 8:
If we divide 50 by 7, we get 7 and a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 17782.57
Subtract 49 from 50 to 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.

Step 9:
When dividing 10 by 7, we get 1 with a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 17782.571
Deduct 7 from 10 and we're left 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 10:
7 goes into 30 4 times with a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 17782.5714
If we take 28 away from 30, we end up 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 11:
20 divided by 7 is 2 with a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 17782.57142
Subtract 14 from 20 to get 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 12:
If we divide 60 by 7, we get 8 and a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 17782.571428
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.

Step 13:
The number 7 fits into 40 5 times, leaving a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 17782.5714285
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.

Moving on to step 14:
7 can be fit into 50 7 times, resulting in a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 17782.57142857
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.

The final outcome is 17782.57142857, with a leftover of 1e-09.
