78054002 divided by 553 
We want to divide 78054002 by 553.

Let's proceed to step 1:
When dividing 7 by 553, we get 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 553

Moving on to step 2:
78 divided by 553 is 0 with a remainder of 78.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 78, we get 78.
Bring next digit (0) of the dividend behind the 78 and repeat the process: 780 / 553

Let's proceed to step 3:
553 goes into 780 1 times with a remainder of 227.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 553 from 780 leaves us with 227.
Take the next digit (5) from the dividend and append it to 227, then repeat: 2275 / 553

Step 4:
If we divide 2275 by 553, we get 4 and a remainder of 63.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
Subtract 2212 from 2275 to get 63.
Grab the next digit (4) from the dividend, add it to 63, then carry on: 634 / 553

Let's proceed to step 5:
If we divide 634 by 553, we get 1 and a remainder of 81.
Use 1 as the next digit of our solution. 
Result so far: 141.0
Deduct 553 from 634 and we're left with 81.
Fetch the next digit (0) from the dividend, attach it to 81 and continue: 810 / 553

On to step 6:
The number 553 fits into 810 1 times, leaving a remainder of 257.
The next digit of our result is 1. 
Result so far: 1411.0
The remainder is 257 after subtracting 553 from 810.
Grab the next digit (0) from the dividend, add it to 257, then carry on: 2570 / 553

Going ahead to step 7:
The number 553 fits into 2570 4 times, leaving a remainder of 358.
Record the quotient 4 as the next digit in the result. 
Result so far: 14114.0
Subtracting 2212 from 2570 leaves us with 358.
Take the next digit (2) from the dividend and append it to 358, then repeat: 3582 / 553

Advancing to step 8:
If we divide 3582 by 553, we get 6 and a remainder of 264.
Write down 6 as next digit of the result. 
Result so far: 141146.0
If we take 3318 away from 3582, we end up with 264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

Step 9:
If we divide 2640 by 553, we get 4 and a remainder of 428.
Use 4 as the next digit of our solution. 
Result so far: 141146.4
The remainder is 428 after subtracting 2212 from 2640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4280, and continue the process.

Moving on to step 10:
553 goes into 4280 7 times with a remainder of 409.
Put 7 as the next digit of the answer. 
Result so far: 141146.47
Subtracting 3871 from 4280 leaves us with 409.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4090, and continue the process.

Moving on to step 11:
553 goes into 4090 7 times with a remainder of 219.
Write down 7 as next digit of the result. 
Result so far: 141146.477
The remainder is 219 after subtracting 3871 from 4090.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2190, and continue the process.

The quotient of the division is 141146.477, and the remainder is 0.0219.
