Let's divide 76178290 by 486
We want to divide 76178290 by 486.

On to step 1:
486 goes into 7 0 times with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Take the next digit (6) from the dividend and append it to 7, then repeat: 76 / 486

Step 2:
If we divide 76 by 486, we get 0 and a remainder of 76.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 76, we end up with 76.
Bring next digit (1) of the dividend behind the 76 and repeat the process: 761 / 486

Going ahead to step 3:
486 goes into 761 1 times with a remainder of 275.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 486 from 761 leaves us with 275.
Take the next digit (7) from the dividend and append it to 275, then repeat: 2757 / 486

Moving on to step 4:
486 goes into 2757 5 times with a remainder of 327.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
Subtract 2430 from 2757 to get 327.
Include the next digit (8) from the dividend after 327, then repeat: 3278 / 486

Step 5:
3278 divided by 486 is 6 with a remainder of 362.
Put 6 as the next digit of the answer. 
Result so far: 156.0
Subtracting 2916 from 3278 leaves us with 362.
Fetch the next digit (2) from the dividend, attach it to 362 and continue: 3622 / 486

Moving on to step 6:
When dividing 3622 by 486, we get 7 with a remainder of 220.
Write down 7 as next digit of the result. 
Result so far: 1567.0
Subtract 3402 from 3622 to get 220.
Grab the next digit (9) from the dividend, add it to 220, then carry on: 2209 / 486

On to step 7:
If we divide 2209 by 486, we get 4 and a remainder of 265.
The next digit of our result is 4. 
Result so far: 15674.0
If we take 1944 away from 2209, we end up with 265.
Append the next digit (0) from the dividend to 265 and continue with: 2650 / 486

On to step 8:
2650 divided by 486 is 5 with a remainder of 220.
Put 5 as the next digit of the answer. 
Result so far: 156745.0
If we subtract 2430 from 2650, we get 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Going ahead to step 9:
When dividing 2200 by 486, we get 4 with a remainder of 256.
Record the quotient 4 as the next digit in the result. 
Result so far: 156745.4
Subtract 1944 from 2200 to get 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Advancing to step 10:
If we divide 2560 by 486, we get 5 and a remainder of 130.
The next digit of our result is 5. 
Result so far: 156745.45
Subtracting 2430 from 2560 leaves us with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

On to step 11:
486 goes into 1300 2 times with a remainder of 328.
Use 2 as the next digit of our solution. 
Result so far: 156745.452
The remainder is 328 after subtracting 972 from 1300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

Step 12:
486 goes into 3280 6 times with a remainder of 364.
Write down 6 as next digit of the result. 
Result so far: 156745.4526
Subtracting 2916 from 3280 leaves us with 364.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

Moving on to step 13:
486 can be fit into 3640 7 times, resulting in a remainder of 238.
The next digit of our result is 7. 
Result so far: 156745.45267
Subtracting 3402 from 3640 leaves us with 238.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

Advancing to step 14:
The number 486 fits into 2380 4 times, leaving a remainder of 436.
Write down 4 as next digit of the result. 
Result so far: 156745.452674
Deduct 1944 from 2380 and we're left with 436.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4360, and continue the process.

Moving on to step 15:
If we divide 4360 by 486, we get 8 and a remainder of 472.
The number 8 becomes the next digit in our result. 
Result so far: 156745.4526748
Subtract 3888 from 4360 to get 472.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4720, and continue the process.

On to step 16:
4720 divided by 486 is 9 with a remainder of 346.
The number 9 becomes the next digit in our result. 
Result so far: 156745.45267489
Deduct 4374 from 4720 and we're left with 346.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3460, and continue the process.

The quotient of the division is 156745.45267489, and the remainder is 3.46e-07.
