Let's divide 64825428 by 840
We want to figure out the number of times 64825428 can be divided by 840.

On to step 1:
The number 840 fits into 6 0 times, leaving a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 840

Going ahead to step 2:
840 goes into 64 0 times with a remainder of 64.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 64, we end up with 64.
Take the next digit (8) from the dividend and append it to 64, then repeat: 648 / 840

Let's proceed to step 3:
648 divided by 840 is 0 with a remainder of 648.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 648 after subtracting 0 from 648.
Bring next digit (2) of the dividend behind the 648 and repeat the process: 6482 / 840

Going ahead to step 4:
When dividing 6482 by 840, we get 7 with a remainder of 602.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
If we subtract 5880 from 6482, we get 602.
Grab the next digit (5) from the dividend, add it to 602, then carry on: 6025 / 840

Step 5:
If we divide 6025 by 840, we get 7 and a remainder of 145.
Put 7 as the next digit of the answer. 
Result so far: 77.0
If we subtract 5880 from 6025, we get 145.
Bring next digit (4) of the dividend behind the 145 and repeat the process: 1454 / 840

Moving on to step 6:
840 can be fit into 1454 1 times, resulting in a remainder of 614.
Use 1 as the next digit of our solution. 
Result so far: 771.0
Subtracting 840 from 1454 leaves us with 614.
Bring next digit (2) of the dividend behind the 614 and repeat the process: 6142 / 840

Advancing to step 7:
When dividing 6142 by 840, we get 7 with a remainder of 262.
Use 7 as the next digit of our solution. 
Result so far: 7717.0
The remainder is 262 after subtracting 5880 from 6142.
Include the next digit (8) from the dividend after 262, then repeat: 2628 / 840

Moving on to step 8:
The number 840 fits into 2628 3 times, leaving a remainder of 108.
Record the quotient 3 as the next digit in the result. 
Result so far: 77173.0
The remainder is 108 after subtracting 2520 from 2628.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Step 9:
If we divide 1080 by 840, we get 1 and a remainder of 240.
Use 1 as the next digit of our solution. 
Result so far: 77173.1
Subtracting 840 from 1080 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.

Going ahead to step 10:
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: 77173.12
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.

Moving on to step 11:
840 goes into 7200 8 times with a remainder of 480.
Write down 8 as next digit of the result. 
Result so far: 77173.128
If we take 6720 away from 7200, we end up 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 12:
If we divide 4800 by 840, we get 5 and a remainder of 600.
Use 5 as the next digit of our solution. 
Result so far: 77173.1285
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.

On to step 13:
The number 840 fits into 6000 7 times, leaving a remainder of 120.
Use 7 as the next digit of our solution. 
Result so far: 77173.12857
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.

Let's proceed to step 14:
The number 840 fits into 1200 1 times, leaving a remainder of 360.
Use 1 as the next digit of our solution. 
Result so far: 77173.128571
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.

On to step 15:
If we divide 3600 by 840, we get 4 and a remainder of 240.
The number 4 becomes the next digit in our result. 
Result so far: 77173.1285714
The remainder is 240 after subtracting 3360 from 3600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Moving on to step 16:
840 goes into 2400 2 times with a remainder of 720.
Write down 2 as next digit of the result. 
Result so far: 77173.12857142
Deduct 1680 from 2400 and we're left 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.

The final outcome is 77173.12857142, with a leftover of 7.2e-07.
