We're dividing 763309 by 57 
We're looking to find how many times 57 goes into 763309.

Advancing to step 1:
57 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
Deduct 0 from 7 and we're left with 7.
Grab the next digit (6) from the dividend, add it to 7, then carry on: 76 / 57

Advancing to step 2:
When dividing 76 by 57, we get 1 with a remainder of 19.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 57 from 76 leaves us with 19.
Include the next digit (3) from the dividend after 19, then repeat: 193 / 57

Advancing to step 3:
57 goes into 193 3 times with a remainder of 22.
Write down 3 as next digit of the result. 
Result so far: 13.0
If we take 171 away from 193, we end up with 22.
Include the next digit (3) from the dividend after 22, then repeat: 223 / 57

Moving on to step 4:
If we divide 223 by 57, we get 3 and a remainder of 52.
The number 3 becomes the next digit in our result. 
Result so far: 133.0
Subtract 171 from 223 to get 52.
Bring next digit (0) of the dividend behind the 52 and repeat the process: 520 / 57

Going ahead to step 5:
57 can be fit into 520 9 times, resulting in a remainder of 7.
Put 9 as the next digit of the answer. 
Result so far: 1339.0
Deduct 513 from 520 and we're left with 7.
Include the next digit (9) from the dividend after 7, then repeat: 79 / 57

Let's proceed to step 6:
The number 57 fits into 79 1 times, leaving a remainder of 22.
Use 1 as the next digit of our solution. 
Result so far: 13391.0
If we take 57 away from 79, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 7:
If we divide 220 by 57, we get 3 and a remainder of 49.
Use 3 as the next digit of our solution. 
Result so far: 13391.3
If we take 171 away from 220, we end up with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Let's proceed to step 8:
490 divided by 57 is 8 with a remainder of 34.
Record the quotient 8 as the next digit in the result. 
Result so far: 13391.38
Subtract 456 from 490 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 9:
When dividing 340 by 57, we get 5 with a remainder of 55.
Put 5 as the next digit of the answer. 
Result so far: 13391.385
Deduct 285 from 340 and we're left with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Advancing to step 10:
When dividing 550 by 57, we get 9 with a remainder of 37.
The next digit of our result is 9. 
Result so far: 13391.3859
The remainder is 37 after subtracting 513 from 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Moving on to step 11:
When dividing 370 by 57, we get 6 with a remainder of 28.
Use 6 as the next digit of our solution. 
Result so far: 13391.38596
Deduct 342 from 370 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 12:
57 goes into 280 4 times with a remainder of 52.
Put 4 as the next digit of the answer. 
Result so far: 13391.385964
Subtract 228 from 280 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Let's proceed to step 13:
57 can be fit into 520 9 times, resulting in a remainder of 7.
Put 9 as the next digit of the answer. 
Result so far: 13391.3859649
If we take 513 away from 520, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 14:
The number 57 fits into 70 1 times, leaving a remainder of 13.
The number 1 becomes the next digit in our result. 
Result so far: 13391.38596491
If we take 57 away from 70, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

In conclusion, the division gives 13391.38596491 with a balance of 1.3e-08.
