We look at the division of 77838317 by 647 
We want to divide 77838317 by 647.

Let's proceed to step 1:
647 can be fit into 7 0 times, resulting in a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Include the next digit (7) from the dividend after 7, then repeat: 77 / 647

On to step 2:
If we divide 77 by 647, we get 0 and a remainder of 77.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 77, we get 77.
Include the next digit (8) from the dividend after 77, then repeat: 778 / 647

Moving on to step 3:
When dividing 778 by 647, we get 1 with a remainder of 131.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 647 away from 778, we end up with 131.
Include the next digit (3) from the dividend after 131, then repeat: 1313 / 647

Step 4:
The number 647 fits into 1313 2 times, leaving a remainder of 19.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
Subtract 1294 from 1313 to get 19.
Take the next digit (8) from the dividend and append it to 19, then repeat: 198 / 647

Moving on to step 5:
When dividing 198 by 647, we get 0 with a remainder of 198.
Record the quotient 0 as the next digit in the result. 
Result so far: 120.0
If we subtract 0 from 198, we get 198.
Bring next digit (3) of the dividend behind the 198 and repeat the process: 1983 / 647

Advancing to step 6:
When dividing 1983 by 647, we get 3 with a remainder of 42.
Use 3 as the next digit of our solution. 
Result so far: 1203.0
Subtracting 1941 from 1983 leaves us with 42.
Include the next digit (1) from the dividend after 42, then repeat: 421 / 647

Going ahead to step 7:
647 can be fit into 421 0 times, resulting in a remainder of 421.
The next digit of our result is 0. 
Result so far: 12030.0
If we subtract 0 from 421, we get 421.
Bring next digit (7) of the dividend behind the 421 and repeat the process: 4217 / 647

Advancing to step 8:
647 goes into 4217 6 times with a remainder of 335.
Write down 6 as next digit of the result. 
Result so far: 120306.0
If we subtract 3882 from 4217, we get 335.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3350, and continue the process.

Let's proceed to step 9:
If we divide 3350 by 647, we get 5 and a remainder of 115.
Record the quotient 5 as the next digit in the result. 
Result so far: 120306.5
The remainder is 115 after subtracting 3235 from 3350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

On to step 10:
647 goes into 1150 1 times with a remainder of 503.
Use 1 as the next digit of our solution. 
Result so far: 120306.51
Deduct 647 from 1150 and we're left with 503.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5030, and continue the process.

Going ahead to step 11:
If we divide 5030 by 647, we get 7 and a remainder of 501.
Record the quotient 7 as the next digit in the result. 
Result so far: 120306.517
If we take 4529 away from 5030, we end up with 501.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5010, and continue the process.

Moving on to step 12:
5010 divided by 647 is 7 with a remainder of 481.
Use 7 as the next digit of our solution. 
Result so far: 120306.5177
Subtracting 4529 from 5010 leaves us with 481.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4810, and continue the process.

The quotient of the division is 120306.5177, and the remainder is 0.00481.
