Let's divide 84030942 by 561
Let's see how many times 561 fits into 84030942.

Step 1:
561 goes into 8 0 times with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Take the next digit (4) from the dividend and append it to 8, then repeat: 84 / 561

Going ahead to step 2:
When dividing 84 by 561, we get 0 with a remainder of 84.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 84 after subtracting 0 from 84.
Fetch the next digit (0) from the dividend, attach it to 84 and continue: 840 / 561

Advancing to step 3:
840 divided by 561 is 1 with a remainder of 279.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 561 away from 840, we end up with 279.
Append the next digit (3) from the dividend to 279 and continue with: 2793 / 561

Step 4:
561 can be fit into 2793 4 times, resulting in a remainder of 549.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
If we subtract 2244 from 2793, we get 549.
Bring next digit (0) of the dividend behind the 549 and repeat the process: 5490 / 561

Step 5:
If we divide 5490 by 561, we get 9 and a remainder of 441.
Use 9 as the next digit of our solution. 
Result so far: 149.0
Deduct 5049 from 5490 and we're left with 441.
Grab the next digit (9) from the dividend, add it to 441, then carry on: 4419 / 561

On to step 6:
If we divide 4419 by 561, we get 7 and a remainder of 492.
Use 7 as the next digit of our solution. 
Result so far: 1497.0
If we subtract 3927 from 4419, we get 492.
Grab the next digit (4) from the dividend, add it to 492, then carry on: 4924 / 561

Moving on to step 7:
561 can be fit into 4924 8 times, resulting in a remainder of 436.
The next digit of our result is 8. 
Result so far: 14978.0
If we take 4488 away from 4924, we end up with 436.
Include the next digit (2) from the dividend after 436, then repeat: 4362 / 561

On to step 8:
The number 561 fits into 4362 7 times, leaving a remainder of 435.
The next digit of our result is 7. 
Result so far: 149787.0
Deduct 3927 from 4362 and we're left with 435.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4350, and continue the process.

Advancing to step 9:
If we divide 4350 by 561, we get 7 and a remainder of 423.
Record the quotient 7 as the next digit in the result. 
Result so far: 149787.7
Subtracting 3927 from 4350 leaves us with 423.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4230, and continue the process.

Step 10:
4230 divided by 561 is 7 with a remainder of 303.
The number 7 becomes the next digit in our result. 
Result so far: 149787.77
If we take 3927 away from 4230, we end up with 303.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3030, and continue the process.

The final result is 149787.77 with a remainder of 0.303.
