51940703 ÷ 387 
We want to figure out the number of times 51940703 can be divided by 387.

Step 1:
If we divide 5 by 387, we get 0 and a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 387

Step 2:
If we divide 51 by 387, we get 0 and a remainder of 51.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 51, we end up with 51.
Take the next digit (9) from the dividend and append it to 51, then repeat: 519 / 387

On to step 3:
387 can be fit into 519 1 times, resulting in a remainder of 132.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 387 from 519 and we're left with 132.
Grab the next digit (4) from the dividend, add it to 132, then carry on: 1324 / 387

Moving on to step 4:
When dividing 1324 by 387, we get 3 with a remainder of 163.
The next digit of our result is 3. 
Result so far: 13.0
Subtract 1161 from 1324 to get 163.
Take the next digit (0) from the dividend and append it to 163, then repeat: 1630 / 387

Step 5:
If we divide 1630 by 387, we get 4 and a remainder of 82.
The number 4 becomes the next digit in our result. 
Result so far: 134.0
Deduct 1548 from 1630 and we're left with 82.
Bring next digit (7) of the dividend behind the 82 and repeat the process: 827 / 387

Advancing to step 6:
If we divide 827 by 387, we get 2 and a remainder of 53.
Write down 2 as next digit of the result. 
Result so far: 1342.0
Subtracting 774 from 827 leaves us with 53.
Take the next digit (0) from the dividend and append it to 53, then repeat: 530 / 387

Let's proceed to step 7:
If we divide 530 by 387, we get 1 and a remainder of 143.
The number 1 becomes the next digit in our result. 
Result so far: 13421.0
If we take 387 away from 530, we end up with 143.
Append the next digit (3) from the dividend to 143 and continue with: 1433 / 387

Advancing to step 8:
If we divide 1433 by 387, we get 3 and a remainder of 272.
The number 3 becomes the next digit in our result. 
Result so far: 134213.0
Subtract 1161 from 1433 to get 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

Let's proceed to step 9:
The number 387 fits into 2720 7 times, leaving a remainder of 11.
Put 7 as the next digit of the answer. 
Result so far: 134213.7
Subtract 2709 from 2720 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 10:
When dividing 110 by 387, we get 0 with a remainder of 110.
Write down 0 as next digit of the result. 
Result so far: 134213.7
Subtract 0 from 110 to get 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Step 11:
When dividing 1100 by 387, we get 2 with a remainder of 326.
Use 2 as the next digit of our solution. 
Result so far: 134213.702
The remainder is 326 after subtracting 774 from 1100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3260, and continue the process.

Moving on to step 12:
387 goes into 3260 8 times with a remainder of 164.
The number 8 becomes the next digit in our result. 
Result so far: 134213.7028
Deduct 3096 from 3260 and we're left with 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Let's proceed to step 13:
387 can be fit into 1640 4 times, resulting in a remainder of 92.
Write down 4 as next digit of the result. 
Result so far: 134213.70284
Subtract 1548 from 1640 to get 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Step 14:
387 goes into 920 2 times with a remainder of 146.
Record the quotient 2 as the next digit in the result. 
Result so far: 134213.702842
Subtract 774 from 920 to get 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

Going ahead to step 15:
If we divide 1460 by 387, we get 3 and a remainder of 299.
The number 3 becomes the next digit in our result. 
Result so far: 134213.7028423
If we take 1161 away from 1460, we end up with 299.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2990, and continue the process.

On to step 16:
387 can be fit into 2990 7 times, resulting in a remainder of 281.
Write down 7 as next digit of the result. 
Result so far: 134213.70284237
Deduct 2709 from 2990 and we're left with 281.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2810, and continue the process.

Our division results in 134213.70284237 with a remaining 2.81e-07.
