We look at the division of 148978 by 7 
Let's see how many times 7 fits into 148978.

Advancing to step 1:
7 goes into 1 0 times with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Append the next digit (4) from the dividend to 1 and continue with: 14 / 7

On to step 2:
7 goes into 14 2 times with a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we subtract 14 from 14, we get 0.
Append the next digit (8) from the dividend to 0 and continue with: 8 / 7

Advancing to step 3:
7 goes into 8 1 times with a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 21.0
If we subtract 7 from 8, we get 1.
Grab the next digit (9) from the dividend, add it to 1, then carry on: 19 / 7

On to step 4:
If we divide 19 by 7, we get 2 and a remainder of 5.
Put 2 as the next digit of the answer. 
Result so far: 212.0
Subtracting 14 from 19 leaves us with 5.
Append the next digit (7) from the dividend to 5 and continue with: 57 / 7

Advancing to step 5:
When dividing 57 by 7, we get 8 with a remainder of 1.
The number 8 becomes the next digit in our result. 
Result so far: 2128.0
Subtract 56 from 57 to get 1.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 7

Let's proceed to step 6:
7 can be fit into 18 2 times, resulting in a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 21282.0
If we take 14 away from 18, 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.

Let's proceed to step 7:
When dividing 40 by 7, we get 5 with a remainder of 5.
The next digit of our result is 5. 
Result so far: 21282.5
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 8:
If we divide 50 by 7, we get 7 and a remainder of 1.
Use 7 as the next digit of our solution. 
Result so far: 21282.57
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.

Step 9:
The number 7 fits into 10 1 times, leaving a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 21282.571
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.

Moving on to step 10:
If we divide 30 by 7, we get 4 and a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 21282.5714
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.

On to step 11:
When dividing 20 by 7, we get 2 with a remainder of 6.
Record the quotient 2 as the next digit in the result. 
Result so far: 21282.57142
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.

On to step 12:
The number 7 fits into 60 8 times, leaving a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 21282.571428
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.

On to step 13:
7 can be fit into 40 5 times, resulting in a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 21282.5714285
Subtracting 35 from 40 leaves us 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 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: 21282.57142857
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.

The quotient of the division is 21282.57142857, and the remainder is 1e-09.
