8448215 divided by 561 
Let's see how many times 561 fits into 8448215.

Advancing to step 1:
8 divided by 561 is 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Append the next digit (4) from the dividend to 8 and continue with: 84 / 561

Moving on to step 2:
The number 561 fits into 84 0 times, leaving a remainder of 84.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 84 after subtracting 0 from 84.
Grab the next digit (4) from the dividend, add it to 84, then carry on: 844 / 561

Let's proceed to step 3:
844 divided by 561 is 1 with a remainder of 283.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 561 from 844 and we're left with 283.
Include the next digit (8) from the dividend after 283, then repeat: 2838 / 561

On to step 4:
When dividing 2838 by 561, we get 5 with a remainder of 33.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
If we subtract 2805 from 2838, we get 33.
Fetch the next digit (2) from the dividend, attach it to 33 and continue: 332 / 561

Moving on to step 5:
If we divide 332 by 561, we get 0 and a remainder of 332.
Record the quotient 0 as the next digit in the result. 
Result so far: 150.0
Subtracting 0 from 332 leaves us with 332.
Take the next digit (1) from the dividend and append it to 332, then repeat: 3321 / 561

Moving on to step 6:
561 can be fit into 3321 5 times, resulting in a remainder of 516.
Record the quotient 5 as the next digit in the result. 
Result so far: 1505.0
Subtract 2805 from 3321 to get 516.
Grab the next digit (5) from the dividend, add it to 516, then carry on: 5165 / 561

Moving on to step 7:
If we divide 5165 by 561, we get 9 and a remainder of 116.
The number 9 becomes the next digit in our result. 
Result so far: 15059.0
The remainder is 116 after subtracting 5049 from 5165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Let's proceed to step 8:
When dividing 1160 by 561, we get 2 with a remainder of 38.
The number 2 becomes the next digit in our result. 
Result so far: 15059.2
Subtract 1122 from 1160 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 9:
If we divide 380 by 561, we get 0 and a remainder of 380.
Record the quotient 0 as the next digit in the result. 
Result so far: 15059.2
The remainder is 380 after subtracting 0 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Moving on to step 10:
The number 561 fits into 3800 6 times, leaving a remainder of 434.
The number 6 becomes the next digit in our result. 
Result so far: 15059.206
If we subtract 3366 from 3800, we get 434.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4340, and continue the process.

Going ahead to step 11:
4340 divided by 561 is 7 with a remainder of 413.
Put 7 as the next digit of the answer. 
Result so far: 15059.2067
Subtracting 3927 from 4340 leaves us with 413.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4130, and continue the process.

Advancing to step 12:
If we divide 4130 by 561, we get 7 and a remainder of 203.
Use 7 as the next digit of our solution. 
Result so far: 15059.20677
If we take 3927 away from 4130, we end up with 203.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2030, and continue the process.

The final result is 15059.20677 with a remainder of 0.000203.
