Let's divide 78505315 by 57
We're looking to find how many times 57 goes into 78505315.

Advancing to step 1:
If we divide 7 by 57, we get 0 and a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 57

On to step 2:
When dividing 78 by 57, we get 1 with a remainder of 21.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 57 from 78 and we're left with 21.
Fetch the next digit (5) from the dividend, attach it to 21 and continue: 215 / 57

Moving on to step 3:
When dividing 215 by 57, we get 3 with a remainder of 44.
The next digit of our result is 3. 
Result so far: 13.0
Subtracting 171 from 215 leaves us with 44.
Take the next digit (0) from the dividend and append it to 44, then repeat: 440 / 57

On to step 4:
If we divide 440 by 57, we get 7 and a remainder of 41.
Put 7 as the next digit of the answer. 
Result so far: 137.0
Subtract 399 from 440 to get 41.
Include the next digit (5) from the dividend after 41, then repeat: 415 / 57

Step 5:
If we divide 415 by 57, we get 7 and a remainder of 16.
Put 7 as the next digit of the answer. 
Result so far: 1377.0
Deduct 399 from 415 and we're left with 16.
Include the next digit (3) from the dividend after 16, then repeat: 163 / 57

Let's proceed to step 6:
When dividing 163 by 57, we get 2 with a remainder of 49.
Use 2 as the next digit of our solution. 
Result so far: 13772.0
Deduct 114 from 163 and we're left with 49.
Fetch the next digit (1) from the dividend, attach it to 49 and continue: 491 / 57

Going ahead to step 7:
57 goes into 491 8 times with a remainder of 35.
The number 8 becomes the next digit in our result. 
Result so far: 137728.0
If we take 456 away from 491, we end up with 35.
Append the next digit (5) from the dividend to 35 and continue with: 355 / 57

Step 8:
57 goes into 355 6 times with a remainder of 13.
The next digit of our result is 6. 
Result so far: 1377286.0
Subtracting 342 from 355 leaves us 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.

Going ahead to step 9:
When dividing 130 by 57, we get 2 with a remainder of 16.
Use 2 as the next digit of our solution. 
Result so far: 1377286.2
Subtracting 114 from 130 leaves us 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.

On to step 10:
160 divided by 57 is 2 with a remainder of 46.
Write down 2 as next digit of the result. 
Result so far: 1377286.22
Deduct 114 from 160 and we're left with 46.
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 1377286.22 with a remainder of 0.046.
