We're dividing 386972 by 49 
We want to figure out the number of times 386972 can be divided by 49.

Moving on to step 1:
The number 49 fits into 3 0 times, leaving a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Append the next digit (8) from the dividend to 3 and continue with: 38 / 49

Advancing to step 2:
If we divide 38 by 49, we get 0 and a remainder of 38.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 38, we end up with 38.
Append the next digit (6) from the dividend to 38 and continue with: 386 / 49

On to step 3:
49 can be fit into 386 7 times, resulting in a remainder of 43.
The next digit of our result is 7. 
Result so far: 7.0
Subtract 343 from 386 to get 43.
Include the next digit (9) from the dividend after 43, then repeat: 439 / 49

Moving on to step 4:
439 divided by 49 is 8 with a remainder of 47.
Put 8 as the next digit of the answer. 
Result so far: 78.0
Deduct 392 from 439 and we're left with 47.
Bring next digit (7) of the dividend behind the 47 and repeat the process: 477 / 49

Advancing to step 5:
The number 49 fits into 477 9 times, leaving a remainder of 36.
Record the quotient 9 as the next digit in the result. 
Result so far: 789.0
Subtracting 441 from 477 leaves us with 36.
Fetch the next digit (2) from the dividend, attach it to 36 and continue: 362 / 49

Moving on to step 6:
If we divide 362 by 49, we get 7 and a remainder of 19.
Write down 7 as next digit of the result. 
Result so far: 7897.0
If we take 343 away from 362, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 7:
When dividing 190 by 49, we get 3 with a remainder of 43.
Put 3 as the next digit of the answer. 
Result so far: 7897.3
Deduct 147 from 190 and we're left 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.

Advancing to step 8:
If we divide 430 by 49, we get 8 and a remainder of 38.
The number 8 becomes the next digit in our result. 
Result so far: 7897.38
The remainder is 38 after subtracting 392 from 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 9:
The number 49 fits into 380 7 times, leaving a remainder of 37.
The number 7 becomes the next digit in our result. 
Result so far: 7897.387
Subtracting 343 from 380 leaves us with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Going ahead to step 10:
370 divided by 49 is 7 with a remainder of 27.
Record the quotient 7 as the next digit in the result. 
Result so far: 7897.3877
Subtract 343 from 370 to get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

After the division, we end up with 7897.3877 and a remainder of 0.00027.
