48513589 ÷ 840 
We want to figure out the number of times 48513589 can be divided by 840.

On to step 1:
840 can be fit into 4 0 times, resulting in a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Take the next digit (8) from the dividend and append it to 4, then repeat: 48 / 840

Moving on to step 2:
If we divide 48 by 840, we get 0 and a remainder of 48.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 48 to get 48.
Include the next digit (5) from the dividend after 48, then repeat: 485 / 840

On to step 3:
840 can be fit into 485 0 times, resulting in a remainder of 485.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 485 to get 485.
Include the next digit (1) from the dividend after 485, then repeat: 4851 / 840

Advancing to step 4:
When dividing 4851 by 840, we get 5 with a remainder of 651.
Use 5 as the next digit of our solution. 
Result so far: 5.0
If we take 4200 away from 4851, we end up with 651.
Append the next digit (3) from the dividend to 651 and continue with: 6513 / 840

On to step 5:
The number 840 fits into 6513 7 times, leaving a remainder of 633.
Write down 7 as next digit of the result. 
Result so far: 57.0
Deduct 5880 from 6513 and we're left with 633.
Grab the next digit (5) from the dividend, add it to 633, then carry on: 6335 / 840

Advancing to step 6:
If we divide 6335 by 840, we get 7 and a remainder of 455.
The number 7 becomes the next digit in our result. 
Result so far: 577.0
Deduct 5880 from 6335 and we're left with 455.
Take the next digit (8) from the dividend and append it to 455, then repeat: 4558 / 840

On to step 7:
840 goes into 4558 5 times with a remainder of 358.
The number 5 becomes the next digit in our result. 
Result so far: 5775.0
If we take 4200 away from 4558, we end up with 358.
Take the next digit (9) from the dividend and append it to 358, then repeat: 3589 / 840

On to step 8:
If we divide 3589 by 840, we get 4 and a remainder of 229.
Use 4 as the next digit of our solution. 
Result so far: 57754.0
If we subtract 3360 from 3589, we get 229.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2290, and continue the process.

Let's proceed to step 9:
840 can be fit into 2290 2 times, resulting in a remainder of 610.
Put 2 as the next digit of the answer. 
Result so far: 57754.2
Subtracting 1680 from 2290 leaves us with 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6100, and continue the process.

Advancing to step 10:
If we divide 6100 by 840, we get 7 and a remainder of 220.
Put 7 as the next digit of the answer. 
Result so far: 57754.27
If we subtract 5880 from 6100, we get 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Let's proceed to step 11:
840 can be fit into 2200 2 times, resulting in a remainder of 520.
The next digit of our result is 2. 
Result so far: 57754.272
Subtracting 1680 from 2200 leaves us with 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Moving on to step 12:
5200 divided by 840 is 6 with a remainder of 160.
Record the quotient 6 as the next digit in the result. 
Result so far: 57754.2726
Subtracting 5040 from 5200 leaves us with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

On to step 13:
The number 840 fits into 1600 1 times, leaving a remainder of 760.
Put 1 as the next digit of the answer. 
Result so far: 57754.27261
The remainder is 760 after subtracting 840 from 1600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7600, and continue the process.

Step 14:
If we divide 7600 by 840, we get 9 and a remainder of 40.
Put 9 as the next digit of the answer. 
Result so far: 57754.272619
Subtract 7560 from 7600 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 15:
If we divide 400 by 840, we get 0 and a remainder of 400.
The next digit of our result is 0. 
Result so far: 57754.272619
If we take 0 away from 400, we end up with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Let's proceed to step 16:
The number 840 fits into 4000 4 times, leaving a remainder of 640.
The next digit of our result is 4. 
Result so far: 57754.27261904
If we subtract 3360 from 4000, we get 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Our division results in 57754.27261904 with a remaining 6.4e-07.
