720336 ÷ 57 
We're looking to find how many times 57 goes into 720336.

Going ahead to step 1:
If we divide 7 by 57, we get 0 and a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Take the next digit (2) from the dividend and append it to 7, then repeat: 72 / 57

Advancing to step 2:
72 divided by 57 is 1 with a remainder of 15.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 57 from 72 leaves us with 15.
Grab the next digit (0) from the dividend, add it to 15, then carry on: 150 / 57

On to step 3:
57 can be fit into 150 2 times, resulting in a remainder of 36.
Put 2 as the next digit of the answer. 
Result so far: 12.0
Deduct 114 from 150 and we're left with 36.
Append the next digit (3) from the dividend to 36 and continue with: 363 / 57

Step 4:
If we divide 363 by 57, we get 6 and a remainder of 21.
Put 6 as the next digit of the answer. 
Result so far: 126.0
Deduct 342 from 363 and we're left with 21.
Take the next digit (3) from the dividend and append it to 21, then repeat: 213 / 57

Moving on to step 5:
If we divide 213 by 57, we get 3 and a remainder of 42.
Record the quotient 3 as the next digit in the result. 
Result so far: 1263.0
If we subtract 171 from 213, we get 42.
Include the next digit (6) from the dividend after 42, then repeat: 426 / 57

On to step 6:
The number 57 fits into 426 7 times, leaving a remainder of 27.
Write down 7 as next digit of the result. 
Result so far: 12637.0
Subtract 399 from 426 to get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Advancing to step 7:
57 can be fit into 270 4 times, resulting in a remainder of 42.
Put 4 as the next digit of the answer. 
Result so far: 12637.4
If we take 228 away from 270, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 8:
The number 57 fits into 420 7 times, leaving a remainder of 21.
Write down 7 as next digit of the result. 
Result so far: 12637.47
If we take 399 away from 420, we end up with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Let's proceed to step 9:
If we divide 210 by 57, we get 3 and a remainder of 39.
The next digit of our result is 3. 
Result so far: 12637.473
If we take 171 away from 210, we end up with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

On to step 10:
When dividing 390 by 57, we get 6 with a remainder of 48.
The next digit of our result is 6. 
Result so far: 12637.4736
Subtracting 342 from 390 leaves us 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.

Step 11:
When dividing 480 by 57, we get 8 with a remainder of 24.
Put 8 as the next digit of the answer. 
Result so far: 12637.47368
If we subtract 456 from 480, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 12:
57 can be fit into 240 4 times, resulting in a remainder of 12.
Record the quotient 4 as the next digit in the result. 
Result so far: 12637.473684
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.

On to step 13:
57 goes into 120 2 times with a remainder of 6.
The number 2 becomes the next digit in our result. 
Result so far: 12637.4736842
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 14:
60 divided by 57 is 1 with a remainder of 3.
The next digit of our result is 1. 
Result so far: 12637.47368421
If we take 57 away from 60, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Our division results in 12637.47368421 with a remaining 3e-09.
