We look at the division of 38939547 by 840 
Let's see how many times 840 fits into 38939547.

Going ahead to step 1:
If we divide 3 by 840, we get 0 and a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Grab the next digit (8) from the dividend, add it to 3, then carry on: 38 / 840

Moving on to step 2:
38 divided by 840 is 0 with a remainder of 38.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 38 and we're left with 38.
Grab the next digit (9) from the dividend, add it to 38, then carry on: 389 / 840

Moving on to step 3:
840 goes into 389 0 times with a remainder of 389.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 389, we end up with 389.
Bring next digit (3) of the dividend behind the 389 and repeat the process: 3893 / 840

On to step 4:
If we divide 3893 by 840, we get 4 and a remainder of 533.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we take 3360 away from 3893, we end up with 533.
Include the next digit (9) from the dividend after 533, then repeat: 5339 / 840

On to step 5:
When dividing 5339 by 840, we get 6 with a remainder of 299.
Put 6 as the next digit of the answer. 
Result so far: 46.0
If we subtract 5040 from 5339, we get 299.
Append the next digit (5) from the dividend to 299 and continue with: 2995 / 840

Advancing to step 6:
If we divide 2995 by 840, we get 3 and a remainder of 475.
Write down 3 as next digit of the result. 
Result so far: 463.0
Subtract 2520 from 2995 to get 475.
Append the next digit (4) from the dividend to 475 and continue with: 4754 / 840

Going ahead to step 7:
When dividing 4754 by 840, we get 5 with a remainder of 554.
The number 5 becomes the next digit in our result. 
Result so far: 4635.0
Subtract 4200 from 4754 to get 554.
Grab the next digit (7) from the dividend, add it to 554, then carry on: 5547 / 840

Let's proceed to step 8:
When dividing 5547 by 840, we get 6 with a remainder of 507.
The number 6 becomes the next digit in our result. 
Result so far: 46356.0
The remainder is 507 after subtracting 5040 from 5547.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5070, and continue the process.

On to step 9:
The number 840 fits into 5070 6 times, leaving a remainder of 30.
The number 6 becomes the next digit in our result. 
Result so far: 46356.6
Subtracting 5040 from 5070 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 10:
300 divided by 840 is 0 with a remainder of 300.
The next digit of our result is 0. 
Result so far: 46356.6
Subtracting 0 from 300 leaves us with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Step 11:
The number 840 fits into 3000 3 times, leaving a remainder of 480.
The next digit of our result is 3. 
Result so far: 46356.603
The remainder is 480 after subtracting 2520 from 3000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Step 12:
840 goes into 4800 5 times with a remainder of 600.
Write down 5 as next digit of the result. 
Result so far: 46356.6035
If we subtract 4200 from 4800, we get 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Let's proceed to step 13:
The number 840 fits into 6000 7 times, leaving a remainder of 120.
Record the quotient 7 as the next digit in the result. 
Result so far: 46356.60357
If we take 5880 away from 6000, we end up with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Advancing to step 14:
840 goes into 1200 1 times with a remainder of 360.
Record the quotient 1 as the next digit in the result. 
Result so far: 46356.603571
Deduct 840 from 1200 and we're left with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

On to step 15:
The number 840 fits into 3600 4 times, leaving a remainder of 240.
Record the quotient 4 as the next digit in the result. 
Result so far: 46356.6035714
If we subtract 3360 from 3600, we get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Step 16:
If we divide 2400 by 840, we get 2 and a remainder of 720.
The next digit of our result is 2. 
Result so far: 46356.60357142
If we take 1680 away from 2400, we end up with 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7200, and continue the process.

In conclusion, the division gives 46356.60357142 with a balance of 7.2e-07.
