40375523 divided by 561 
We want to divide 40375523 by 561.

Let's proceed to step 1:
When dividing 4 by 561, we get 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Include the next digit (0) from the dividend after 4, then repeat: 40 / 561

Step 2:
When dividing 40 by 561, we get 0 with a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 40, we end up with 40.
Append the next digit (3) from the dividend to 40 and continue with: 403 / 561

Going ahead to step 3:
561 can be fit into 403 0 times, resulting in a remainder of 403.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 403, we end up with 403.
Bring next digit (7) of the dividend behind the 403 and repeat the process: 4037 / 561

Let's proceed to step 4:
The number 561 fits into 4037 7 times, leaving a remainder of 110.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
The remainder is 110 after subtracting 3927 from 4037.
Grab the next digit (5) from the dividend, add it to 110, then carry on: 1105 / 561

Step 5:
If we divide 1105 by 561, we get 1 and a remainder of 544.
The next digit of our result is 1. 
Result so far: 71.0
If we subtract 561 from 1105, we get 544.
Take the next digit (5) from the dividend and append it to 544, then repeat: 5445 / 561

Moving on to step 6:
The number 561 fits into 5445 9 times, leaving a remainder of 396.
The next digit of our result is 9. 
Result so far: 719.0
Subtracting 5049 from 5445 leaves us with 396.
Include the next digit (2) from the dividend after 396, then repeat: 3962 / 561

Going ahead to step 7:
561 goes into 3962 7 times with a remainder of 35.
Record the quotient 7 as the next digit in the result. 
Result so far: 7197.0
The remainder is 35 after subtracting 3927 from 3962.
Take the next digit (3) from the dividend and append it to 35, then repeat: 353 / 561

Moving on to step 8:
The number 561 fits into 353 0 times, leaving a remainder of 353.
The next digit of our result is 0. 
Result so far: 71970.0
Deduct 0 from 353 and we're left with 353.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3530, and continue the process.

Let's proceed to step 9:
561 can be fit into 3530 6 times, resulting in a remainder of 164.
The next digit of our result is 6. 
Result so far: 71970.6
If we subtract 3366 from 3530, we get 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Moving on to step 10:
When dividing 1640 by 561, we get 2 with a remainder of 518.
Put 2 as the next digit of the answer. 
Result so far: 71970.62
Subtract 1122 from 1640 to get 518.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5180, and continue the process.

Let's proceed to step 11:
If we divide 5180 by 561, we get 9 and a remainder of 131.
The next digit of our result is 9. 
Result so far: 71970.629
Deduct 5049 from 5180 and we're left with 131.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1310, and continue the process.

Advancing to step 12:
561 goes into 1310 2 times with a remainder of 188.
Record the quotient 2 as the next digit in the result. 
Result so far: 71970.6292
Subtracting 1122 from 1310 leaves us with 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Moving on to step 13:
561 goes into 1880 3 times with a remainder of 197.
The number 3 becomes the next digit in our result. 
Result so far: 71970.62923
Deduct 1683 from 1880 and we're left with 197.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1970, and continue the process.

Moving on to step 14:
561 goes into 1970 3 times with a remainder of 287.
Use 3 as the next digit of our solution. 
Result so far: 71970.629233
Subtracting 1683 from 1970 leaves us with 287.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2870, and continue the process.

In conclusion, the division gives 71970.629233 with a balance of 2.87e-05.
