We're dividing 84038084 by 648 
Our goal is to divide 84038084 by 648.

Going ahead to step 1:
648 goes into 8 0 times with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Append the next digit (4) from the dividend to 8 and continue with: 84 / 648

Going ahead to step 2:
84 divided by 648 is 0 with a remainder of 84.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 84 after subtracting 0 from 84.
Fetch the next digit (0) from the dividend, attach it to 84 and continue: 840 / 648

Advancing to step 3:
648 goes into 840 1 times with a remainder of 192.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 648 from 840 to get 192.
Grab the next digit (3) from the dividend, add it to 192, then carry on: 1923 / 648

Step 4:
648 goes into 1923 2 times with a remainder of 627.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
If we subtract 1296 from 1923, we get 627.
Bring next digit (8) of the dividend behind the 627 and repeat the process: 6278 / 648

Step 5:
648 goes into 6278 9 times with a remainder of 446.
Record the quotient 9 as the next digit in the result. 
Result so far: 129.0
The remainder is 446 after subtracting 5832 from 6278.
Fetch the next digit (0) from the dividend, attach it to 446 and continue: 4460 / 648

Going ahead to step 6:
When dividing 4460 by 648, we get 6 with a remainder of 572.
Use 6 as the next digit of our solution. 
Result so far: 1296.0
If we subtract 3888 from 4460, we get 572.
Bring next digit (8) of the dividend behind the 572 and repeat the process: 5728 / 648

Step 7:
If we divide 5728 by 648, we get 8 and a remainder of 544.
Record the quotient 8 as the next digit in the result. 
Result so far: 12968.0
The remainder is 544 after subtracting 5184 from 5728.
Bring next digit (4) of the dividend behind the 544 and repeat the process: 5444 / 648

Going ahead to step 8:
When dividing 5444 by 648, we get 8 with a remainder of 260.
Use 8 as the next digit of our solution. 
Result so far: 129688.0
If we subtract 5184 from 5444, we get 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Step 9:
The number 648 fits into 2600 4 times, leaving a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 129688.4
Subtracting 2592 from 2600 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 10:
When dividing 80 by 648, we get 0 with a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 129688.4
Deduct 0 from 80 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 11:
648 goes into 800 1 times with a remainder of 152.
Write down 1 as next digit of the result. 
Result so far: 129688.401
If we take 648 away from 800, we end up with 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Let's proceed to step 12:
648 can be fit into 1520 2 times, resulting in a remainder of 224.
Record the quotient 2 as the next digit in the result. 
Result so far: 129688.4012
The remainder is 224 after subtracting 1296 from 1520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Step 13:
2240 divided by 648 is 3 with a remainder of 296.
Use 3 as the next digit of our solution. 
Result so far: 129688.40123
The remainder is 296 after subtracting 1944 from 2240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

Let's proceed to step 14:
648 can be fit into 2960 4 times, resulting in a remainder of 368.
Write down 4 as next digit of the result. 
Result so far: 129688.401234
Deduct 2592 from 2960 and we're left with 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

On to step 15:
648 can be fit into 3680 5 times, resulting in a remainder of 440.
Record the quotient 5 as the next digit in the result. 
Result so far: 129688.4012345
If we take 3240 away from 3680, we end up with 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Moving on to step 16:
648 goes into 4400 6 times with a remainder of 512.
Put 6 as the next digit of the answer. 
Result so far: 129688.40123456
If we take 3888 away from 4400, we end up with 512.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5120, and continue the process.

Our division results in 129688.40123456 with a remaining 5.12e-07.
