778960 divided by 57 
We want to figure out the number of times 778960 can be divided by 57.

Advancing to step 1:
57 can be fit into 7 0 times, resulting in a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Append the next digit (7) from the dividend to 7 and continue with: 77 / 57

Moving on to step 2:
If we divide 77 by 57, we get 1 and a remainder of 20.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 57 from 77 leaves us with 20.
Grab the next digit (8) from the dividend, add it to 20, then carry on: 208 / 57

On to step 3:
208 divided by 57 is 3 with a remainder of 37.
Put 3 as the next digit of the answer. 
Result so far: 13.0
Deduct 171 from 208 and we're left with 37.
Append the next digit (9) from the dividend to 37 and continue with: 379 / 57

Step 4:
If we divide 379 by 57, we get 6 and a remainder of 37.
Use 6 as the next digit of our solution. 
Result so far: 136.0
If we take 342 away from 379, we end up with 37.
Append the next digit (6) from the dividend to 37 and continue with: 376 / 57

Moving on to step 5:
The number 57 fits into 376 6 times, leaving a remainder of 34.
Use 6 as the next digit of our solution. 
Result so far: 1366.0
If we subtract 342 from 376, we get 34.
Fetch the next digit (0) from the dividend, attach it to 34 and continue: 340 / 57

Let's proceed to step 6:
340 divided by 57 is 5 with a remainder of 55.
Write down 5 as next digit of the result. 
Result so far: 13665.0
If we take 285 away from 340, we end up 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 7:
When dividing 550 by 57, we get 9 with a remainder of 37.
Use 9 as the next digit of our solution. 
Result so far: 13665.9
Subtract 513 from 550 to get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Let's proceed to step 8:
When dividing 370 by 57, we get 6 with a remainder of 28.
The number 6 becomes the next digit in our result. 
Result so far: 13665.96
If we take 342 away from 370, we end up 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.

Step 9:
57 goes into 280 4 times with a remainder of 52.
Use 4 as the next digit of our solution. 
Result so far: 13665.964
The remainder is 52 after subtracting 228 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Step 10:
57 can be fit into 520 9 times, resulting in a remainder of 7.
Use 9 as the next digit of our solution. 
Result so far: 13665.9649
Deduct 513 from 520 and we're left 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.

Let's proceed to step 11:
70 divided by 57 is 1 with a remainder of 13.
The next digit of our result is 1. 
Result so far: 13665.96491
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.

Let's proceed to step 12:
When dividing 130 by 57, we get 2 with a remainder of 16.
Record the quotient 2 as the next digit in the result. 
Result so far: 13665.964912
If we take 114 away from 130, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 13:
57 can be fit into 160 2 times, resulting in a remainder of 46.
The number 2 becomes the next digit in our result. 
Result so far: 13665.9649122
The remainder is 46 after subtracting 114 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

The final result is 13665.9649122 with a remainder of 4.6e-07.
