561990 ÷ 7 
We want to divide 561990 by 7.

Going ahead to step 1:
When dividing 5 by 7, we get 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Bring next digit (6) of the dividend behind the 5 and repeat the process: 56 / 7

Advancing to step 2:
When dividing 56 by 7, we get 8 with a remainder of 0.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
If we subtract 56 from 56, we get 0.
Grab the next digit (1) from the dividend, add it to 0, then carry on: 1 / 7

Moving on to step 3:
If we divide 1 by 7, we get 0 and a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 80.0
Subtract 0 from 1 to get 1.
Fetch the next digit (9) from the dividend, attach it to 1 and continue: 19 / 7

Advancing to step 4:
7 goes into 19 2 times with a remainder of 5.
Write down 2 as next digit of the result. 
Result so far: 802.0
If we subtract 14 from 19, we get 5.
Fetch the next digit (9) from the dividend, attach it to 5 and continue: 59 / 7

Going ahead to step 5:
7 goes into 59 8 times with a remainder of 3.
Put 8 as the next digit of the answer. 
Result so far: 8028.0
Deduct 56 from 59 and we're left with 3.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 7

Advancing to step 6:
If we divide 30 by 7, we get 4 and a remainder of 2.
The next digit of our result is 4. 
Result so far: 80284.0
If we subtract 28 from 30, we 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.

Let's proceed to step 7:
20 divided by 7 is 2 with a remainder of 6.
The next digit of our result is 2. 
Result so far: 80284.2
Deduct 14 from 20 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 8:
7 goes into 60 8 times with a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 80284.28
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 9:
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: 80284.285
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 10:
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: 80284.2857
The remainder is 1 after subtracting 49 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 11:
The number 7 fits into 10 1 times, leaving a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 80284.28571
The remainder is 3 after subtracting 7 from 10.
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 12:
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: 80284.285714
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 13:
The number 7 fits into 20 2 times, leaving a remainder of 6.
Use 2 as the next digit of our solution. 
Result so far: 80284.2857142
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.

Moving on to step 14:
The number 7 fits into 60 8 times, leaving a remainder of 4.
The next digit of our result is 8. 
Result so far: 80284.28571428
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.

Our division results in 80284.28571428 with a remaining 4e-09.
