We're dividing 278542 by 202 
We're looking to find how many times 202 goes into 278542.

Advancing to step 1:
2 divided by 202 is 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Bring next digit (7) of the dividend behind the 2 and repeat the process: 27 / 202

Moving on to step 2:
202 can be fit into 27 0 times, resulting in a remainder of 27.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 27 and we're left with 27.
Append the next digit (8) from the dividend to 27 and continue with: 278 / 202

Going ahead to step 3:
278 divided by 202 is 1 with a remainder of 76.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 202 from 278 to get 76.
Fetch the next digit (5) from the dividend, attach it to 76 and continue: 765 / 202

On to step 4:
The number 202 fits into 765 3 times, leaving a remainder of 159.
The next digit of our result is 3. 
Result so far: 13.0
Subtracting 606 from 765 leaves us with 159.
Take the next digit (4) from the dividend and append it to 159, then repeat: 1594 / 202

Step 5:
The number 202 fits into 1594 7 times, leaving a remainder of 180.
The number 7 becomes the next digit in our result. 
Result so far: 137.0
If we take 1414 away from 1594, we end up with 180.
Include the next digit (2) from the dividend after 180, then repeat: 1802 / 202

Let's proceed to step 6:
When dividing 1802 by 202, we get 8 with a remainder of 186.
The number 8 becomes the next digit in our result. 
Result so far: 1378.0
Subtract 1616 from 1802 to get 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

Advancing to step 7:
1860 divided by 202 is 9 with a remainder of 42.
Write down 9 as next digit of the result. 
Result so far: 1378.9
The remainder is 42 after subtracting 1818 from 1860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 8:
When dividing 420 by 202, we get 2 with a remainder of 16.
Use 2 as the next digit of our solution. 
Result so far: 1378.92
If we take 404 away from 420, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 9:
202 can be fit into 160 0 times, resulting in a remainder of 160.
Record the quotient 0 as the next digit in the result. 
Result so far: 1378.92
The remainder is 160 after subtracting 0 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Step 10:
1600 divided by 202 is 7 with a remainder of 186.
Write down 7 as next digit of the result. 
Result so far: 1378.9207
Subtract 1414 from 1600 to get 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

On to step 11:
The number 202 fits into 1860 9 times, leaving a remainder of 42.
Record the quotient 9 as the next digit in the result. 
Result so far: 1378.92079
Subtract 1818 from 1860 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 12:
202 goes into 420 2 times with a remainder of 16.
The next digit of our result is 2. 
Result so far: 1378.920792
If we subtract 404 from 420, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 13:
The number 202 fits into 160 0 times, leaving a remainder of 160.
Write down 0 as next digit of the result. 
Result so far: 1378.920792
Subtracting 0 from 160 leaves us with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Advancing to step 14:
1600 divided by 202 is 7 with a remainder of 186.
Record the quotient 7 as the next digit in the result. 
Result so far: 1378.92079207
The remainder is 186 after subtracting 1414 from 1600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

The final outcome is 1378.92079207, with a leftover of 1.86e-07.
