We look at the division of 866978 by 49 
We want to figure out the number of times 866978 can be divided by 49.

Step 1:
When dividing 8 by 49, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 49

Going ahead to step 2:
49 can be fit into 86 1 times, resulting in a remainder of 37.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 49 away from 86, we end up with 37.
Bring next digit (6) of the dividend behind the 37 and repeat the process: 376 / 49

Step 3:
When dividing 376 by 49, we get 7 with a remainder of 33.
The next digit of our result is 7. 
Result so far: 17.0
Deduct 343 from 376 and we're left with 33.
Fetch the next digit (9) from the dividend, attach it to 33 and continue: 339 / 49

Let's proceed to step 4:
49 can be fit into 339 6 times, resulting in a remainder of 45.
Write down 6 as next digit of the result. 
Result so far: 176.0
If we subtract 294 from 339, we get 45.
Fetch the next digit (7) from the dividend, attach it to 45 and continue: 457 / 49

Moving on to step 5:
49 goes into 457 9 times with a remainder of 16.
The number 9 becomes the next digit in our result. 
Result so far: 1769.0
Subtract 441 from 457 to get 16.
Grab the next digit (8) from the dividend, add it to 16, then carry on: 168 / 49

Step 6:
168 divided by 49 is 3 with a remainder of 21.
The number 3 becomes the next digit in our result. 
Result so far: 17693.0
Subtracting 147 from 168 leaves us with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 7:
49 can be fit into 210 4 times, resulting in a remainder of 14.
The next digit of our result is 4. 
Result so far: 17693.4
Subtracting 196 from 210 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 8:
If we divide 140 by 49, we get 2 and a remainder of 42.
Record the quotient 2 as the next digit in the result. 
Result so far: 17693.42
Subtract 98 from 140 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.

Step 9:
49 can be fit into 420 8 times, resulting in a remainder of 28.
Use 8 as the next digit of our solution. 
Result so far: 17693.428
If we take 392 away from 420, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 10:
When dividing 280 by 49, we get 5 with a remainder of 35.
Use 5 as the next digit of our solution. 
Result so far: 17693.4285
Deduct 245 from 280 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

On to step 11:
350 divided by 49 is 7 with a remainder of 7.
Put 7 as the next digit of the answer. 
Result so far: 17693.42857
If we subtract 343 from 350, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 12:
When dividing 70 by 49, we get 1 with a remainder of 21.
Record the quotient 1 as the next digit in the result. 
Result so far: 17693.428571
If we subtract 49 from 70, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Let's proceed to step 13:
49 goes into 210 4 times with a remainder of 14.
Record the quotient 4 as the next digit in the result. 
Result so far: 17693.4285714
Subtract 196 from 210 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 14:
49 goes into 140 2 times with a remainder of 42.
Record the quotient 2 as the next digit in the result. 
Result so far: 17693.42857142
Subtracting 98 from 140 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

The final result is 17693.42857142 with a remainder of 4.2e-08.
