Let's divide 561901 by 1
We want to divide 561901 by 1.

Step 1:
The number 1 fits into 5 5 times, leaving a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 5.0
If we take 5 away from 5, we end up with 0.
Take the next digit (6) from the dividend and append it to 0, then repeat: 6 / 1

Let's proceed to step 2:
1 goes into 6 6 times with a remainder of 0.
Use 6 as the next digit of our solution. 
Result so far: 56.0
Deduct 6 from 6 and we're left with 0.
Grab the next digit (1) from the dividend, add it to 0, then carry on: 1 / 1

Going ahead to step 3:
1 can be fit into 1 1 times, resulting in a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 561.0
Subtract 1 from 1 to get 0.
Fetch the next digit (9) from the dividend, attach it to 0 and continue: 9 / 1

Step 4:
1 goes into 9 9 times with a remainder of 0.
The next digit of our result is 9. 
Result so far: 5619.0
The remainder is 0 after subtracting 9 from 9.
Bring next digit (0) of the dividend behind the 0 and repeat the process: 0 / 1

Advancing to step 5:
0 divided by 1 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 56190.0
If we subtract 0 from 0, we get 0.
Append the next digit (1) from the dividend to 0 and continue with: 1 / 1

On to step 6:
The number 1 fits into 1 1 times, leaving a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 561901.0
The remainder is 0 after subtracting 1 from 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 7:
0 divided by 1 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 561901.0
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 8:
1 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 561901.0
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 561901.0 with a remainder of 0.0.
