55180015 ÷ 279 
We want to divide 55180015 by 279.

Advancing to step 1:
The number 279 fits into 5 0 times, leaving a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Bring next digit (5) of the dividend behind the 5 and repeat the process: 55 / 279

Advancing to step 2:
279 goes into 55 0 times with a remainder of 55.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 55, we end up with 55.
Grab the next digit (1) from the dividend, add it to 55, then carry on: 551 / 279

Let's proceed to step 3:
The number 279 fits into 551 1 times, leaving a remainder of 272.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 279 from 551, we get 272.
Bring next digit (8) of the dividend behind the 272 and repeat the process: 2728 / 279

On to step 4:
When dividing 2728 by 279, we get 9 with a remainder of 217.
The number 9 becomes the next digit in our result. 
Result so far: 19.0
The remainder is 217 after subtracting 2511 from 2728.
Bring next digit (0) of the dividend behind the 217 and repeat the process: 2170 / 279

Moving on to step 5:
When dividing 2170 by 279, we get 7 with a remainder of 217.
The next digit of our result is 7. 
Result so far: 197.0
If we take 1953 away from 2170, we end up with 217.
Fetch the next digit (0) from the dividend, attach it to 217 and continue: 2170 / 279

Going ahead to step 6:
279 can be fit into 2170 7 times, resulting in a remainder of 217.
The next digit of our result is 7. 
Result so far: 1977.0
If we take 1953 away from 2170, we end up with 217.
Fetch the next digit (1) from the dividend, attach it to 217 and continue: 2171 / 279

Step 7:
If we divide 2171 by 279, we get 7 and a remainder of 218.
Write down 7 as next digit of the result. 
Result so far: 19777.0
Subtracting 1953 from 2171 leaves us with 218.
Append the next digit (5) from the dividend to 218 and continue with: 2185 / 279

Let's proceed to step 8:
279 can be fit into 2185 7 times, resulting in a remainder of 232.
Write down 7 as next digit of the result. 
Result so far: 197777.0
Subtract 1953 from 2185 to get 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Step 9:
The number 279 fits into 2320 8 times, leaving a remainder of 88.
Put 8 as the next digit of the answer. 
Result so far: 197777.8
If we subtract 2232 from 2320, we get 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Moving on to step 10:
880 divided by 279 is 3 with a remainder of 43.
Use 3 as the next digit of our solution. 
Result so far: 197777.83
Subtracting 837 from 880 leaves us with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Going ahead to step 11:
When dividing 430 by 279, we get 1 with a remainder of 151.
The next digit of our result is 1. 
Result so far: 197777.831
The remainder is 151 after subtracting 279 from 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1510, and continue the process.

Advancing to step 12:
279 goes into 1510 5 times with a remainder of 115.
The number 5 becomes the next digit in our result. 
Result so far: 197777.8315
Subtracting 1395 from 1510 leaves us with 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Advancing to step 13:
The number 279 fits into 1150 4 times, leaving a remainder of 34.
Use 4 as the next digit of our solution. 
Result so far: 197777.83154
The remainder is 34 after subtracting 1116 from 1150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 14:
279 can be fit into 340 1 times, resulting in a remainder of 61.
Use 1 as the next digit of our solution. 
Result so far: 197777.831541
Deduct 279 from 340 and we're left with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Moving on to step 15:
279 goes into 610 2 times with a remainder of 52.
Record the quotient 2 as the next digit in the result. 
Result so far: 197777.8315412
Subtract 558 from 610 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Moving on to step 16:
520 divided by 279 is 1 with a remainder of 241.
The number 1 becomes the next digit in our result. 
Result so far: 197777.83154121
The remainder is 241 after subtracting 279 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2410, and continue the process.

The final outcome is 197777.83154121, with a leftover of 2.41e-07.
