21500505 ÷ 57 
We want to divide 21500505 by 57.

Let's proceed to step 1:
When dividing 2 by 57, we get 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 57

Let's proceed to step 2:
If we divide 21 by 57, we get 0 and a remainder of 21.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 21 and we're left with 21.
Take the next digit (5) from the dividend and append it to 21, then repeat: 215 / 57

Moving on to step 3:
57 goes into 215 3 times with a remainder of 44.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtract 171 from 215 to get 44.
Take the next digit (0) from the dividend and append it to 44, then repeat: 440 / 57

Let's proceed to step 4:
57 goes into 440 7 times with a remainder of 41.
Put 7 as the next digit of the answer. 
Result so far: 37.0
The remainder is 41 after subtracting 399 from 440.
Include the next digit (0) from the dividend after 41, then repeat: 410 / 57

Let's proceed to step 5:
If we divide 410 by 57, we get 7 and a remainder of 11.
Put 7 as the next digit of the answer. 
Result so far: 377.0
If we subtract 399 from 410, we get 11.
Include the next digit (5) from the dividend after 11, then repeat: 115 / 57

Advancing to step 6:
The number 57 fits into 115 2 times, leaving a remainder of 1.
Record the quotient 2 as the next digit in the result. 
Result so far: 3772.0
If we take 114 away from 115, we end up with 1.
Fetch the next digit (0) from the dividend, attach it to 1 and continue: 10 / 57

Advancing to step 7:
10 divided by 57 is 0 with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 37720.0
Subtracting 0 from 10 leaves us with 10.
Include the next digit (5) from the dividend after 10, then repeat: 105 / 57

Step 8:
The number 57 fits into 105 1 times, leaving a remainder of 48.
Put 1 as the next digit of the answer. 
Result so far: 377201.0
Deduct 57 from 105 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 9:
57 goes into 480 8 times with a remainder of 24.
The number 8 becomes the next digit in our result. 
Result so far: 377201.8
Deduct 456 from 480 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 10:
240 divided by 57 is 4 with a remainder of 12.
Record the quotient 4 as the next digit in the result. 
Result so far: 377201.84
If we take 228 away from 240, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 11:
57 goes into 120 2 times with a remainder of 6.
The next digit of our result is 2. 
Result so far: 377201.842
If we subtract 114 from 120, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 12:
57 goes into 60 1 times with a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 377201.8421
Subtract 57 from 60 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 13:
57 can be fit into 30 0 times, resulting in a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 377201.8421
If we subtract 0 from 30, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 14:
When dividing 300 by 57, we get 5 with a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 377201.842105
Subtracting 285 from 300 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 15:
If we divide 150 by 57, we get 2 and a remainder of 36.
Record the quotient 2 as the next digit in the result. 
Result so far: 377201.8421052
Subtract 114 from 150 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 16:
If we divide 360 by 57, we get 6 and a remainder of 18.
Use 6 as the next digit of our solution. 
Result so far: 377201.84210526
Deduct 342 from 360 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

The final result is 377201.84210526 with a remainder of 1.8e-08.
