73821381 divided by 561 
We want to figure out the number of times 73821381 can be divided by 561.

On to step 1:
561 can be fit into 7 0 times, resulting in a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Fetch the next digit (3) from the dividend, attach it to 7 and continue: 73 / 561

Step 2:
When dividing 73 by 561, we get 0 with a remainder of 73.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 73, we end up with 73.
Append the next digit (8) from the dividend to 73 and continue with: 738 / 561

Going ahead to step 3:
When dividing 738 by 561, we get 1 with a remainder of 177.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 561 from 738 and we're left with 177.
Append the next digit (2) from the dividend to 177 and continue with: 1772 / 561

Moving on to step 4:
When dividing 1772 by 561, we get 3 with a remainder of 89.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
If we take 1683 away from 1772, we end up with 89.
Fetch the next digit (1) from the dividend, attach it to 89 and continue: 891 / 561

Moving on to step 5:
The number 561 fits into 891 1 times, leaving a remainder of 330.
Record the quotient 1 as the next digit in the result. 
Result so far: 131.0
Deduct 561 from 891 and we're left with 330.
Take the next digit (3) from the dividend and append it to 330, then repeat: 3303 / 561

On to step 6:
If we divide 3303 by 561, we get 5 and a remainder of 498.
Put 5 as the next digit of the answer. 
Result so far: 1315.0
If we take 2805 away from 3303, we end up with 498.
Take the next digit (8) from the dividend and append it to 498, then repeat: 4988 / 561

Let's proceed to step 7:
561 can be fit into 4988 8 times, resulting in a remainder of 500.
Write down 8 as next digit of the result. 
Result so far: 13158.0
Deduct 4488 from 4988 and we're left with 500.
Grab the next digit (1) from the dividend, add it to 500, then carry on: 5001 / 561

Let's proceed to step 8:
561 goes into 5001 8 times with a remainder of 513.
The next digit of our result is 8. 
Result so far: 131588.0
The remainder is 513 after subtracting 4488 from 5001.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5130, and continue the process.

On to step 9:
561 can be fit into 5130 9 times, resulting in a remainder of 81.
Use 9 as the next digit of our solution. 
Result so far: 131588.9
If we subtract 5049 from 5130, we get 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Step 10:
The number 561 fits into 810 1 times, leaving a remainder of 249.
The next digit of our result is 1. 
Result so far: 131588.91
If we take 561 away from 810, we end up with 249.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2490, and continue the process.

Step 11:
The number 561 fits into 2490 4 times, leaving a remainder of 246.
The number 4 becomes the next digit in our result. 
Result so far: 131588.914
If we take 2244 away from 2490, we end up with 246.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2460, and continue the process.

Going ahead to step 12:
561 goes into 2460 4 times with a remainder of 216.
Put 4 as the next digit of the answer. 
Result so far: 131588.9144
Subtract 2244 from 2460 to get 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

In conclusion, the division gives 131588.9144 with a balance of 0.00216.
