Let's divide 78144252 by 557
We're looking to find how many times 557 goes into 78144252.

Moving on to step 1:
When dividing 7 by 557, we get 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 557

Let's proceed to step 2:
If we divide 78 by 557, we get 0 and a remainder of 78.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 78 to get 78.
Bring next digit (1) of the dividend behind the 78 and repeat the process: 781 / 557

Going ahead to step 3:
557 goes into 781 1 times with a remainder of 224.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 224 after subtracting 557 from 781.
Take the next digit (4) from the dividend and append it to 224, then repeat: 2244 / 557

On to step 4:
2244 divided by 557 is 4 with a remainder of 16.
Write down 4 as next digit of the result. 
Result so far: 14.0
The remainder is 16 after subtracting 2228 from 2244.
Take the next digit (4) from the dividend and append it to 16, then repeat: 164 / 557

Advancing to step 5:
If we divide 164 by 557, we get 0 and a remainder of 164.
Use 0 as the next digit of our solution. 
Result so far: 140.0
The remainder is 164 after subtracting 0 from 164.
Fetch the next digit (2) from the dividend, attach it to 164 and continue: 1642 / 557

Moving on to step 6:
557 goes into 1642 2 times with a remainder of 528.
Write down 2 as next digit of the result. 
Result so far: 1402.0
Subtracting 1114 from 1642 leaves us with 528.
Append the next digit (5) from the dividend to 528 and continue with: 5285 / 557

On to step 7:
If we divide 5285 by 557, we get 9 and a remainder of 272.
Use 9 as the next digit of our solution. 
Result so far: 14029.0
Subtract 5013 from 5285 to get 272.
Take the next digit (2) from the dividend and append it to 272, then repeat: 2722 / 557

Advancing to step 8:
When dividing 2722 by 557, we get 4 with a remainder of 494.
The next digit of our result is 4. 
Result so far: 140294.0
Deduct 2228 from 2722 and we're left with 494.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4940, and continue the process.

Advancing to step 9:
The number 557 fits into 4940 8 times, leaving a remainder of 484.
The next digit of our result is 8. 
Result so far: 140294.8
If we subtract 4456 from 4940, we get 484.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4840, and continue the process.

Advancing to step 10:
If we divide 4840 by 557, we get 8 and a remainder of 384.
Put 8 as the next digit of the answer. 
Result so far: 140294.88
If we take 4456 away from 4840, we end up with 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

After the division, we end up with 140294.88 and a remainder of 0.384.
