We look at the division of 7748311 by 649 
We want to divide 7748311 by 649.

On to step 1:
649 goes into 7 0 times with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Grab the next digit (7) from the dividend, add it to 7, then carry on: 77 / 649

Going ahead to step 2:
The number 649 fits into 77 0 times, leaving a remainder of 77.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 77 leaves us with 77.
Bring next digit (4) of the dividend behind the 77 and repeat the process: 774 / 649

Let's proceed to step 3:
649 goes into 774 1 times with a remainder of 125.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 649 from 774 and we're left with 125.
Include the next digit (8) from the dividend after 125, then repeat: 1258 / 649

Moving on to step 4:
649 goes into 1258 1 times with a remainder of 609.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
Subtracting 649 from 1258 leaves us with 609.
Bring next digit (3) of the dividend behind the 609 and repeat the process: 6093 / 649

Going ahead to step 5:
6093 divided by 649 is 9 with a remainder of 252.
Write down 9 as next digit of the result. 
Result so far: 119.0
If we subtract 5841 from 6093, we get 252.
Bring next digit (1) of the dividend behind the 252 and repeat the process: 2521 / 649

Going ahead to step 6:
The number 649 fits into 2521 3 times, leaving a remainder of 574.
Record the quotient 3 as the next digit in the result. 
Result so far: 1193.0
Subtract 1947 from 2521 to get 574.
Take the next digit (1) from the dividend and append it to 574, then repeat: 5741 / 649

Going ahead to step 7:
The number 649 fits into 5741 8 times, leaving a remainder of 549.
Write down 8 as next digit of the result. 
Result so far: 11938.0
If we subtract 5192 from 5741, we get 549.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5490, and continue the process.

Going ahead to step 8:
5490 divided by 649 is 8 with a remainder of 298.
The number 8 becomes the next digit in our result. 
Result so far: 11938.8
If we take 5192 away from 5490, we end up with 298.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2980, and continue the process.

Step 9:
2980 divided by 649 is 4 with a remainder of 384.
The next digit of our result is 4. 
Result so far: 11938.84
Subtracting 2596 from 2980 leaves us with 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Advancing to step 10:
The number 649 fits into 3840 5 times, leaving a remainder of 595.
The number 5 becomes the next digit in our result. 
Result so far: 11938.845
Subtracting 3245 from 3840 leaves us with 595.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5950, and continue the process.

On to step 11:
The number 649 fits into 5950 9 times, leaving a remainder of 109.
Put 9 as the next digit of the answer. 
Result so far: 11938.8459
Deduct 5841 from 5950 and we're left with 109.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1090, and continue the process.

On to step 12:
When dividing 1090 by 649, we get 1 with a remainder of 441.
Record the quotient 1 as the next digit in the result. 
Result so far: 11938.84591
Subtracting 649 from 1090 leaves us with 441.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4410, and continue the process.

Moving on to step 13:
4410 divided by 649 is 6 with a remainder of 516.
Use 6 as the next digit of our solution. 
Result so far: 11938.845916
Deduct 3894 from 4410 and we're left with 516.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5160, and continue the process.

Advancing to step 14:
If we divide 5160 by 649, we get 7 and a remainder of 617.
Use 7 as the next digit of our solution. 
Result so far: 11938.8459167
Deduct 4543 from 5160 and we're left with 617.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6170, and continue the process.

On to step 15:
649 can be fit into 6170 9 times, resulting in a remainder of 329.
The number 9 becomes the next digit in our result. 
Result so far: 11938.84591679
If we subtract 5841 from 6170, we get 329.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3290, and continue the process.

The final outcome is 11938.84591679, with a leftover of 3.29e-07.
