We want to figure out the number of times 56406398 can be divided by 278.

On to step 1:
The number 278 fits into 5 0 times, leaving a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Append the next digit (6) from the dividend to 5 and continue with: 56 / 278

On to step 2:
56 divided by 278 is 0 with a remainder of 56.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 56, we get 56.
Grab the next digit (4) from the dividend, add it to 56, then carry on: 564 / 278

Let's proceed to step 3:
278 can be fit into 564 2 times, resulting in a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Deduct 556 from 564 and we're left with 8.
Take the next digit (0) from the dividend and append it to 8, then repeat: 80 / 278

On to step 4:
When dividing 80 by 278, we get 0 with a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 20.0
If we take 0 away from 80, we end up with 80.
Grab the next digit (6) from the dividend, add it to 80, then carry on: 806 / 278

Advancing to step 5:
The number 278 fits into 806 2 times, leaving a remainder of 250.
The number 2 becomes the next digit in our result. 
Result so far: 202.0
Deduct 556 from 806 and we're left with 250.
Take the next digit (3) from the dividend and append it to 250, then repeat: 2503 / 278

Going ahead to step 6:
When dividing 2503 by 278, we get 9 with a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 2029.0
If we subtract 2502 from 2503, we get 1.
Fetch the next digit (9) from the dividend, attach it to 1 and continue: 19 / 278

Advancing to step 7:
19 divided by 278 is 0 with a remainder of 19.
Put 0 as the next digit of the answer. 
Result so far: 20290.0
If we take 0 away from 19, we end up with 19.
Take the next digit (8) from the dividend and append it to 19, then repeat: 198 / 278

Advancing to step 8:
When dividing 198 by 278, we get 0 with a remainder of 198.
The next digit of our result is 0. 
Result so far: 202900.0
Deduct 0 from 198 and we're left with 198.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1980, and continue the process.

Moving on to step 9:
1980 divided by 278 is 7 with a remainder of 34.
The next digit of our result is 7. 
Result so far: 202900.7
The remainder is 34 after subtracting 1946 from 1980.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 10:
340 divided by 278 is 1 with a remainder of 62.
Write down 1 as next digit of the result. 
Result so far: 202900.71
If we subtract 278 from 340, we get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Moving on to step 11:
278 goes into 620 2 times with a remainder of 64.
Put 2 as the next digit of the answer. 
Result so far: 202900.712
The remainder is 64 after subtracting 556 from 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

On to step 12:
640 divided by 278 is 2 with a remainder of 84.
Record the quotient 2 as the next digit in the result. 
Result so far: 202900.7122
If we take 556 away from 640, we end up with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Our division results in 202900.7122 with a remaining 0.00084.
