51487682 divided by 387 
We want to divide 51487682 by 387.

On to step 1:
If we divide 5 by 387, we get 0 and a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Include the next digit (1) from the dividend after 5, then repeat: 51 / 387

Step 2:
The number 387 fits into 51 0 times, leaving a remainder of 51.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 51 after subtracting 0 from 51.
Bring next digit (4) of the dividend behind the 51 and repeat the process: 514 / 387

Advancing to step 3:
387 goes into 514 1 times with a remainder of 127.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 127 after subtracting 387 from 514.
Grab the next digit (8) from the dividend, add it to 127, then carry on: 1278 / 387

Advancing to step 4:
If we divide 1278 by 387, we get 3 and a remainder of 117.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
The remainder is 117 after subtracting 1161 from 1278.
Grab the next digit (7) from the dividend, add it to 117, then carry on: 1177 / 387

On to step 5:
If we divide 1177 by 387, we get 3 and a remainder of 16.
Write down 3 as next digit of the result. 
Result so far: 133.0
Deduct 1161 from 1177 and we're left with 16.
Grab the next digit (6) from the dividend, add it to 16, then carry on: 166 / 387

Moving on to step 6:
The number 387 fits into 166 0 times, leaving a remainder of 166.
The next digit of our result is 0. 
Result so far: 1330.0
Subtract 0 from 166 to get 166.
Take the next digit (8) from the dividend and append it to 166, then repeat: 1668 / 387

Step 7:
The number 387 fits into 1668 4 times, leaving a remainder of 120.
Write down 4 as next digit of the result. 
Result so far: 13304.0
Deduct 1548 from 1668 and we're left with 120.
Take the next digit (2) from the dividend and append it to 120, then repeat: 1202 / 387

On to step 8:
387 goes into 1202 3 times with a remainder of 41.
Record the quotient 3 as the next digit in the result. 
Result so far: 133043.0
If we subtract 1161 from 1202, we get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Advancing to step 9:
387 can be fit into 410 1 times, resulting in a remainder of 23.
The number 1 becomes the next digit in our result. 
Result so far: 133043.1
Subtracting 387 from 410 leaves us with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Advancing to step 10:
When dividing 230 by 387, we get 0 with a remainder of 230.
Record the quotient 0 as the next digit in the result. 
Result so far: 133043.1
Subtracting 0 from 230 leaves us with 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Advancing to step 11:
2300 divided by 387 is 5 with a remainder of 365.
Use 5 as the next digit of our solution. 
Result so far: 133043.105
If we take 1935 away from 2300, we end up with 365.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3650, and continue the process.

Let's proceed to step 12:
If we divide 3650 by 387, we get 9 and a remainder of 167.
Write down 9 as next digit of the result. 
Result so far: 133043.1059
If we subtract 3483 from 3650, we get 167.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1670, and continue the process.

Advancing to step 13:
If we divide 1670 by 387, we get 4 and a remainder of 122.
Use 4 as the next digit of our solution. 
Result so far: 133043.10594
If we take 1548 away from 1670, we end up with 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

Step 14:
If we divide 1220 by 387, we get 3 and a remainder of 59.
Write down 3 as next digit of the result. 
Result so far: 133043.105943
Subtracting 1161 from 1220 leaves us with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Going ahead to step 15:
If we divide 590 by 387, we get 1 and a remainder of 203.
The next digit of our result is 1. 
Result so far: 133043.1059431
If we take 387 away from 590, we end up with 203.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2030, and continue the process.

Advancing to step 16:
When dividing 2030 by 387, we get 5 with a remainder of 95.
The next digit of our result is 5. 
Result so far: 133043.10594315
If we subtract 1935 from 2030, we get 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

The quotient of the division is 133043.10594315, and the remainder is 9.5e-08.
