Let's divide 13598484 by 840
We want to figure out the number of times 13598484 can be divided by 840.

Step 1:
840 can be fit into 1 0 times, resulting in a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 840

Going ahead to step 2:
The number 840 fits into 13 0 times, leaving a remainder of 13.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 13 to get 13.
Grab the next digit (5) from the dividend, add it to 13, then carry on: 135 / 840

Moving on to step 3:
The number 840 fits into 135 0 times, leaving a remainder of 135.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 135 leaves us with 135.
Include the next digit (9) from the dividend after 135, then repeat: 1359 / 840

Let's proceed to step 4:
If we divide 1359 by 840, we get 1 and a remainder of 519.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 840 from 1359 leaves us with 519.
Bring next digit (8) of the dividend behind the 519 and repeat the process: 5198 / 840

Step 5:
840 can be fit into 5198 6 times, resulting in a remainder of 158.
Write down 6 as next digit of the result. 
Result so far: 16.0
If we take 5040 away from 5198, we end up with 158.
Bring next digit (4) of the dividend behind the 158 and repeat the process: 1584 / 840

On to step 6:
840 goes into 1584 1 times with a remainder of 744.
Record the quotient 1 as the next digit in the result. 
Result so far: 161.0
The remainder is 744 after subtracting 840 from 1584.
Take the next digit (8) from the dividend and append it to 744, then repeat: 7448 / 840

Moving on to step 7:
When dividing 7448 by 840, we get 8 with a remainder of 728.
The next digit of our result is 8. 
Result so far: 1618.0
If we take 6720 away from 7448, we end up with 728.
Take the next digit (4) from the dividend and append it to 728, then repeat: 7284 / 840

On to step 8:
When dividing 7284 by 840, we get 8 with a remainder of 564.
Use 8 as the next digit of our solution. 
Result so far: 16188.0
Subtracting 6720 from 7284 leaves us with 564.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5640, and continue the process.

Going ahead to step 9:
840 goes into 5640 6 times with a remainder of 600.
The number 6 becomes the next digit in our result. 
Result so far: 16188.6
If we take 5040 away from 5640, we end up with 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Moving on to step 10:
If we divide 6000 by 840, we get 7 and a remainder of 120.
The next digit of our result is 7. 
Result so far: 16188.67
If we subtract 5880 from 6000, we get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

On to step 11:
840 goes into 1200 1 times with a remainder of 360.
The number 1 becomes the next digit in our result. 
Result so far: 16188.671
If we subtract 840 from 1200, we get 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Step 12:
3600 divided by 840 is 4 with a remainder of 240.
Use 4 as the next digit of our solution. 
Result so far: 16188.6714
Subtracting 3360 from 3600 leaves us with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Advancing to step 13:
If we divide 2400 by 840, we get 2 and a remainder of 720.
Record the quotient 2 as the next digit in the result. 
Result so far: 16188.67142
If we subtract 1680 from 2400, we get 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7200, and continue the process.

Let's proceed to step 14:
840 can be fit into 7200 8 times, resulting in a remainder of 480.
Use 8 as the next digit of our solution. 
Result so far: 16188.671428
Deduct 6720 from 7200 and we're left with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Let's proceed to step 15:
When dividing 4800 by 840, we get 5 with a remainder of 600.
Record the quotient 5 as the next digit in the result. 
Result so far: 16188.6714285
Subtracting 4200 from 4800 leaves us with 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Moving on to step 16:
840 can be fit into 6000 7 times, resulting in a remainder of 120.
Put 7 as the next digit of the answer. 
Result so far: 16188.67142857
The remainder is 120 after subtracting 5880 from 6000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Our division results in 16188.67142857 with a remaining 1.2e-07.
