Let's divide 78333090 by 550
We want to figure out the number of times 78333090 can be divided by 550.

Step 1:
550 goes into 7 0 times with 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.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 550

Moving on to step 2:
When dividing 78 by 550, we get 0 with a remainder of 78.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 78, we end up with 78.
Append the next digit (3) from the dividend to 78 and continue with: 783 / 550

Let's proceed to step 3:
783 divided by 550 is 1 with a remainder of 233.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 550 away from 783, we end up with 233.
Grab the next digit (3) from the dividend, add it to 233, then carry on: 2333 / 550

Step 4:
2333 divided by 550 is 4 with a remainder of 133.
Write down 4 as next digit of the result. 
Result so far: 14.0
If we subtract 2200 from 2333, we get 133.
Bring next digit (3) of the dividend behind the 133 and repeat the process: 1333 / 550

Let's proceed to step 5:
The number 550 fits into 1333 2 times, leaving a remainder of 233.
Record the quotient 2 as the next digit in the result. 
Result so far: 142.0
If we take 1100 away from 1333, we end up with 233.
Bring next digit (0) of the dividend behind the 233 and repeat the process: 2330 / 550

Advancing to step 6:
550 goes into 2330 4 times with a remainder of 130.
Use 4 as the next digit of our solution. 
Result so far: 1424.0
Subtract 2200 from 2330 to get 130.
Append the next digit (9) from the dividend to 130 and continue with: 1309 / 550

On to step 7:
The number 550 fits into 1309 2 times, leaving a remainder of 209.
Record the quotient 2 as the next digit in the result. 
Result so far: 14242.0
The remainder is 209 after subtracting 1100 from 1309.
Fetch the next digit (0) from the dividend, attach it to 209 and continue: 2090 / 550

Advancing to step 8:
2090 divided by 550 is 3 with a remainder of 440.
Use 3 as the next digit of our solution. 
Result so far: 142423.0
If we subtract 1650 from 2090, we get 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Going ahead to step 9:
550 goes into 4400 8 times with a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 142423.8
Deduct 4400 from 4400 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 10:
550 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 142423.8
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 11:
550 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 142423.8
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 142423.8, with a leftover of 0.0.
