Let's divide 78193086 by 552
We want to divide 78193086 by 552.

Advancing to step 1:
The number 552 fits into 7 0 times, leaving a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 552

Moving on to step 2:
78 divided by 552 is 0 with a remainder of 78.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 78, we get 78.
Fetch the next digit (1) from the dividend, attach it to 78 and continue: 781 / 552

Let's proceed to step 3:
781 divided by 552 is 1 with a remainder of 229.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 552 away from 781, we end up with 229.
Include the next digit (9) from the dividend after 229, then repeat: 2299 / 552

Going ahead to step 4:
The number 552 fits into 2299 4 times, leaving a remainder of 91.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
If we subtract 2208 from 2299, we get 91.
Take the next digit (3) from the dividend and append it to 91, then repeat: 913 / 552

Let's proceed to step 5:
The number 552 fits into 913 1 times, leaving a remainder of 361.
Write down 1 as next digit of the result. 
Result so far: 141.0
Deduct 552 from 913 and we're left with 361.
Include the next digit (0) from the dividend after 361, then repeat: 3610 / 552

Advancing to step 6:
552 goes into 3610 6 times with a remainder of 298.
The number 6 becomes the next digit in our result. 
Result so far: 1416.0
Subtract 3312 from 3610 to get 298.
Grab the next digit (8) from the dividend, add it to 298, then carry on: 2988 / 552

Let's proceed to step 7:
2988 divided by 552 is 5 with a remainder of 228.
Record the quotient 5 as the next digit in the result. 
Result so far: 14165.0
If we take 2760 away from 2988, we end up with 228.
Fetch the next digit (6) from the dividend, attach it to 228 and continue: 2286 / 552

On to step 8:
If we divide 2286 by 552, we get 4 and a remainder of 78.
Write down 4 as next digit of the result. 
Result so far: 141654.0
Subtracting 2208 from 2286 leaves us with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

On to step 9:
When dividing 780 by 552, we get 1 with a remainder of 228.
Record the quotient 1 as the next digit in the result. 
Result so far: 141654.1
Deduct 552 from 780 and we're left with 228.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

Going ahead to step 10:
If we divide 2280 by 552, we get 4 and a remainder of 72.
Put 4 as the next digit of the answer. 
Result so far: 141654.14
If we subtract 2208 from 2280, we get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Advancing to step 11:
552 goes into 720 1 times with a remainder of 168.
The number 1 becomes the next digit in our result. 
Result so far: 141654.141
Subtracting 552 from 720 leaves us with 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Going ahead to step 12:
552 can be fit into 1680 3 times, resulting in a remainder of 24.
Put 3 as the next digit of the answer. 
Result so far: 141654.1413
Subtracting 1656 from 1680 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 13:
The number 552 fits into 240 0 times, leaving a remainder of 240.
The next digit of our result is 0. 
Result so far: 141654.1413
The remainder is 240 after subtracting 0 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Moving on to step 14:
552 goes into 2400 4 times with a remainder of 192.
Put 4 as the next digit of the answer. 
Result so far: 141654.141304
If we subtract 2208 from 2400, we get 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Advancing to step 15:
1920 divided by 552 is 3 with a remainder of 264.
The next digit of our result is 3. 
Result so far: 141654.1413043
The remainder is 264 after subtracting 1656 from 1920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

Advancing to step 16:
If we divide 2640 by 552, we get 4 and a remainder of 432.
The next digit of our result is 4. 
Result so far: 141654.14130434
Subtract 2208 from 2640 to get 432.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4320, and continue the process.

After the division, we end up with 141654.14130434 and a remainder of 4.32e-07.
