Let's divide 557372 by 78
We want to figure out the number of times 557372 can be divided by 78.

Step 1:
78 goes into 5 0 times with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Append the next digit (5) from the dividend to 5 and continue with: 55 / 78

Going ahead to step 2:
If we divide 55 by 78, we get 0 and a remainder of 55.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 55, we get 55.
Append the next digit (7) from the dividend to 55 and continue with: 557 / 78

Advancing to step 3:
If we divide 557 by 78, we get 7 and a remainder of 11.
Put 7 as the next digit of the answer. 
Result so far: 7.0
The remainder is 11 after subtracting 546 from 557.
Grab the next digit (3) from the dividend, add it to 11, then carry on: 113 / 78

Moving on to step 4:
If we divide 113 by 78, we get 1 and a remainder of 35.
The number 1 becomes the next digit in our result. 
Result so far: 71.0
Subtracting 78 from 113 leaves us with 35.
Append the next digit (7) from the dividend to 35 and continue with: 357 / 78

Advancing to step 5:
If we divide 357 by 78, we get 4 and a remainder of 45.
Put 4 as the next digit of the answer. 
Result so far: 714.0
The remainder is 45 after subtracting 312 from 357.
Append the next digit (2) from the dividend to 45 and continue with: 452 / 78

Advancing to step 6:
If we divide 452 by 78, we get 5 and a remainder of 62.
Use 5 as the next digit of our solution. 
Result so far: 7145.0
Subtracting 390 from 452 leaves us with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Step 7:
620 divided by 78 is 7 with a remainder of 74.
Use 7 as the next digit of our solution. 
Result so far: 7145.7
Subtracting 546 from 620 leaves us with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Advancing to step 8:
When dividing 740 by 78, we get 9 with a remainder of 38.
Use 9 as the next digit of our solution. 
Result so far: 7145.79
If we take 702 away from 740, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 9:
78 can be fit into 380 4 times, resulting in a remainder of 68.
Record the quotient 4 as the next digit in the result. 
Result so far: 7145.794
If we take 312 away from 380, we end up with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Moving on to step 10:
The number 78 fits into 680 8 times, leaving a remainder of 56.
Use 8 as the next digit of our solution. 
Result so far: 7145.7948
If we subtract 624 from 680, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Advancing to step 11:
78 can be fit into 560 7 times, resulting in a remainder of 14.
Use 7 as the next digit of our solution. 
Result so far: 7145.79487
If we take 546 away from 560, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 12:
If we divide 140 by 78, we get 1 and a remainder of 62.
Write down 1 as next digit of the result. 
Result so far: 7145.794871
If we take 78 away from 140, we end up with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Going ahead to step 13:
If we divide 620 by 78, we get 7 and a remainder of 74.
Record the quotient 7 as the next digit in the result. 
Result so far: 7145.7948717
If we take 546 away from 620, we end up with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Step 14:
78 goes into 740 9 times with a remainder of 38.
Put 9 as the next digit of the answer. 
Result so far: 7145.79487179
The remainder is 38 after subtracting 702 from 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

The final outcome is 7145.79487179, with a leftover of 3.8e-08.
