Let's divide 81360674 by 561
We want to figure out the number of times 81360674 can be divided by 561.

Moving on to step 1:
561 can be fit into 8 0 times, resulting in a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 561

Moving on to step 2:
The number 561 fits into 81 0 times, leaving a remainder of 81.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 81 to get 81.
Fetch the next digit (3) from the dividend, attach it to 81 and continue: 813 / 561

Let's proceed to step 3:
813 divided by 561 is 1 with a remainder of 252.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 561 from 813 and we're left with 252.
Grab the next digit (6) from the dividend, add it to 252, then carry on: 2526 / 561

Advancing to step 4:
If we divide 2526 by 561, we get 4 and a remainder of 282.
Put 4 as the next digit of the answer. 
Result so far: 14.0
Deduct 2244 from 2526 and we're left with 282.
Include the next digit (0) from the dividend after 282, then repeat: 2820 / 561

Advancing to step 5:
561 goes into 2820 5 times with a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 145.0
Subtract 2805 from 2820 to get 15.
Append the next digit (6) from the dividend to 15 and continue with: 156 / 561

Step 6:
When dividing 156 by 561, we get 0 with a remainder of 156.
Write down 0 as next digit of the result. 
Result so far: 1450.0
Deduct 0 from 156 and we're left with 156.
Include the next digit (7) from the dividend after 156, then repeat: 1567 / 561

Moving on to step 7:
When dividing 1567 by 561, we get 2 with a remainder of 445.
Put 2 as the next digit of the answer. 
Result so far: 14502.0
The remainder is 445 after subtracting 1122 from 1567.
Take the next digit (4) from the dividend and append it to 445, then repeat: 4454 / 561

Step 8:
561 goes into 4454 7 times with a remainder of 527.
Record the quotient 7 as the next digit in the result. 
Result so far: 145027.0
Subtracting 3927 from 4454 leaves us with 527.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5270, and continue the process.

Advancing to step 9:
The number 561 fits into 5270 9 times, leaving a remainder of 221.
Put 9 as the next digit of the answer. 
Result so far: 145027.9
Subtracting 5049 from 5270 leaves us with 221.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2210, and continue the process.

Moving on to step 10:
If we divide 2210 by 561, we get 3 and a remainder of 527.
Put 3 as the next digit of the answer. 
Result so far: 145027.93
Deduct 1683 from 2210 and we're left with 527.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5270, and continue the process.

Advancing to step 11:
5270 divided by 561 is 9 with a remainder of 221.
Write down 9 as next digit of the result. 
Result so far: 145027.939
If we subtract 5049 from 5270, we get 221.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2210, and continue the process.

Going ahead to step 12:
561 goes into 2210 3 times with a remainder of 527.
Put 3 as the next digit of the answer. 
Result so far: 145027.9393
If we subtract 1683 from 2210, we get 527.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5270, and continue the process.

Advancing to step 13:
5270 divided by 561 is 9 with a remainder of 221.
Write down 9 as next digit of the result. 
Result so far: 145027.93939
If we take 5049 away from 5270, we end up with 221.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2210, and continue the process.

Let's proceed to step 14:
If we divide 2210 by 561, we get 3 and a remainder of 527.
Write down 3 as next digit of the result. 
Result so far: 145027.939393
The remainder is 527 after subtracting 1683 from 2210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5270, and continue the process.

On to step 15:
The number 561 fits into 5270 9 times, leaving a remainder of 221.
Put 9 as the next digit of the answer. 
Result so far: 145027.9393939
Deduct 5049 from 5270 and we're left with 221.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2210, and continue the process.

On to step 16:
If we divide 2210 by 561, we get 3 and a remainder of 527.
Use 3 as the next digit of our solution. 
Result so far: 145027.93939393
Subtracting 1683 from 2210 leaves us with 527.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5270, and continue the process.

The final outcome is 145027.93939393, with a leftover of 5.27e-07.
