76138278 ÷ 649 
Our goal is to divide 76138278 by 649.

On to step 1:
7 divided by 649 is 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Bring next digit (6) of the dividend behind the 7 and repeat the process: 76 / 649

Moving on to step 2:
If we divide 76 by 649, we get 0 and a remainder of 76.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 76, we get 76.
Include the next digit (1) from the dividend after 76, then repeat: 761 / 649

Moving on to step 3:
761 divided by 649 is 1 with a remainder of 112.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 649 from 761 to get 112.
Fetch the next digit (3) from the dividend, attach it to 112 and continue: 1123 / 649

On to step 4:
1123 divided by 649 is 1 with a remainder of 474.
Write down 1 as next digit of the result. 
Result so far: 11.0
The remainder is 474 after subtracting 649 from 1123.
Take the next digit (8) from the dividend and append it to 474, then repeat: 4748 / 649

Advancing to step 5:
The number 649 fits into 4748 7 times, leaving a remainder of 205.
The number 7 becomes the next digit in our result. 
Result so far: 117.0
The remainder is 205 after subtracting 4543 from 4748.
Append the next digit (2) from the dividend to 205 and continue with: 2052 / 649

Step 6:
649 goes into 2052 3 times with a remainder of 105.
The number 3 becomes the next digit in our result. 
Result so far: 1173.0
If we take 1947 away from 2052, we end up with 105.
Bring next digit (7) of the dividend behind the 105 and repeat the process: 1057 / 649

Advancing to step 7:
The number 649 fits into 1057 1 times, leaving a remainder of 408.
Put 1 as the next digit of the answer. 
Result so far: 11731.0
Subtracting 649 from 1057 leaves us with 408.
Bring next digit (8) of the dividend behind the 408 and repeat the process: 4088 / 649

On to step 8:
649 goes into 4088 6 times with a remainder of 194.
The number 6 becomes the next digit in our result. 
Result so far: 117316.0
If we subtract 3894 from 4088, we get 194.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1940, and continue the process.

Moving on to step 9:
649 goes into 1940 2 times with a remainder of 642.
Put 2 as the next digit of the answer. 
Result so far: 117316.2
Subtracting 1298 from 1940 leaves us with 642.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6420, and continue the process.

Going ahead to step 10:
6420 divided by 649 is 9 with a remainder of 579.
Put 9 as the next digit of the answer. 
Result so far: 117316.29
If we subtract 5841 from 6420, we get 579.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5790, and continue the process.

Moving on to step 11:
When dividing 5790 by 649, we get 8 with a remainder of 598.
Put 8 as the next digit of the answer. 
Result so far: 117316.298
If we take 5192 away from 5790, we end up with 598.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5980, and continue the process.

Advancing to step 12:
649 can be fit into 5980 9 times, resulting in a remainder of 139.
The next digit of our result is 9. 
Result so far: 117316.2989
If we subtract 5841 from 5980, we get 139.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1390, and continue the process.

Step 13:
If we divide 1390 by 649, we get 2 and a remainder of 92.
Use 2 as the next digit of our solution. 
Result so far: 117316.29892
The remainder is 92 after subtracting 1298 from 1390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Moving on to step 14:
649 goes into 920 1 times with a remainder of 271.
Record the quotient 1 as the next digit in the result. 
Result so far: 117316.298921
Subtracting 649 from 920 leaves us with 271.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2710, and continue the process.

Let's proceed to step 15:
649 goes into 2710 4 times with a remainder of 114.
Use 4 as the next digit of our solution. 
Result so far: 117316.2989214
The remainder is 114 after subtracting 2596 from 2710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

Advancing to step 16:
When dividing 1140 by 649, we get 1 with a remainder of 491.
The number 1 becomes the next digit in our result. 
Result so far: 117316.29892141
If we take 649 away from 1140, we end up with 491.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4910, and continue the process.

Our division results in 117316.29892141 with a remaining 4.91e-07.
