We're dividing 149290 by 7 
We want to figure out the number of times 149290 can be divided by 7.

Let's proceed 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
Deduct 0 from 1 and we're left with 1.
Include the next digit (4) from the dividend after 1, then repeat: 14 / 7

On to step 2:
7 can be fit into 14 2 times, resulting in a remainder of 0.
The next digit of our result is 2. 
Result so far: 2.0
The remainder is 0 after subtracting 14 from 14.
Grab the next digit (9) from the dividend, add it to 0, then carry on: 9 / 7

Let's proceed to step 3:
When dividing 9 by 7, we get 1 with a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 21.0
If we take 7 away from 9, we end up with 2.
Bring next digit (2) of the dividend behind the 2 and repeat the process: 22 / 7

Advancing to step 4:
The number 7 fits into 22 3 times, leaving a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 213.0
Deduct 21 from 22 and we're left with 1.
Bring next digit (9) of the dividend behind the 1 and repeat the process: 19 / 7

Let's proceed to step 5:
When dividing 19 by 7, we get 2 with a remainder of 5.
Record the quotient 2 as the next digit in the result. 
Result so far: 2132.0
If we take 14 away from 19, we end up with 5.
Fetch the next digit (0) from the dividend, attach it to 5 and continue: 50 / 7

Step 6:
50 divided by 7 is 7 with a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 21327.0
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.

Moving on to step 7:
7 can be fit into 10 1 times, resulting in a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 21327.1
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.

On to step 8:
30 divided by 7 is 4 with a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 21327.14
The remainder is 2 after subtracting 28 from 30.
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 9:
7 can be fit into 20 2 times, resulting in a remainder of 6.
The next digit of our result is 2. 
Result so far: 21327.142
If we subtract 14 from 20, we 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 10:
7 goes into 60 8 times with a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 21327.1428
Deduct 56 from 60 and we're left 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.

Moving on to step 11:
7 can be fit into 40 5 times, resulting in a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 21327.14285
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.

Let's proceed to step 12:
If we divide 50 by 7, we get 7 and a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 21327.142857
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 13:
If we divide 10 by 7, we get 1 and a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 21327.1428571
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 14:
7 can be fit into 30 4 times, resulting in a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 21327.14285714
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.

The final outcome is 21327.14285714, with a leftover of 2e-09.
