990387 divided by 7 
We want to divide 990387 by 7.

Step 1:
If we divide 9 by 7, we get 1 and a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 7 away from 9, we end up with 2.
Include the next digit (9) from the dividend after 2, then repeat: 29 / 7

Going ahead to step 2:
29 divided by 7 is 4 with a remainder of 1.
The next digit of our result is 4. 
Result so far: 14.0
If we take 28 away from 29, we end up with 1.
Grab the next digit (0) from the dividend, add it to 1, then carry on: 10 / 7

Moving on to step 3:
When dividing 10 by 7, we get 1 with a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 141.0
Subtracting 7 from 10 leaves us with 3.
Include the next digit (3) from the dividend after 3, then repeat: 33 / 7

Let's proceed to step 4:
The number 7 fits into 33 4 times, leaving a remainder of 5.
Put 4 as the next digit of the answer. 
Result so far: 1414.0
Subtracting 28 from 33 leaves us with 5.
Take the next digit (8) from the dividend and append it to 5, then repeat: 58 / 7

On to step 5:
7 goes into 58 8 times with a remainder of 2.
Use 8 as the next digit of our solution. 
Result so far: 14148.0
If we subtract 56 from 58, we get 2.
Append the next digit (7) from the dividend to 2 and continue with: 27 / 7

Advancing to step 6:
7 can be fit into 27 3 times, resulting in a remainder of 6.
Record the quotient 3 as the next digit in the result. 
Result so far: 141483.0
The remainder is 6 after subtracting 21 from 27.
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 7:
7 can be fit into 60 8 times, resulting in a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 141483.8
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 8:
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: 141483.85
The remainder is 5 after subtracting 35 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 9:
When dividing 50 by 7, we get 7 with a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 141483.857
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 10:
When dividing 10 by 7, we get 1 with a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 141483.8571
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.

Advancing to step 11:
The number 7 fits into 30 4 times, leaving a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 141483.85714
Subtracting 28 from 30 leaves us 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 12:
The number 7 fits into 20 2 times, leaving a remainder of 6.
Write down 2 as next digit of the result. 
Result so far: 141483.857142
The remainder is 6 after subtracting 14 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 13:
The number 7 fits into 60 8 times, leaving a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 141483.8571428
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.

Moving on to step 14:
The number 7 fits into 40 5 times, leaving a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 141483.85714285
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.

The final outcome is 141483.85714285, with a leftover of 5e-09.
