99642740 ÷ 387 
Our goal is to divide 99642740 by 387.

On to step 1:
387 can be fit into 9 0 times, resulting in a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Take the next digit (9) from the dividend and append it to 9, then repeat: 99 / 387

Step 2:
99 divided by 387 is 0 with a remainder of 99.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 99 leaves us with 99.
Bring next digit (6) of the dividend behind the 99 and repeat the process: 996 / 387

Advancing to step 3:
387 goes into 996 2 times with a remainder of 222.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Deduct 774 from 996 and we're left with 222.
Append the next digit (4) from the dividend to 222 and continue with: 2224 / 387

Going ahead to step 4:
The number 387 fits into 2224 5 times, leaving a remainder of 289.
Write down 5 as next digit of the result. 
Result so far: 25.0
If we take 1935 away from 2224, we end up with 289.
Append the next digit (2) from the dividend to 289 and continue with: 2892 / 387

Going ahead to step 5:
2892 divided by 387 is 7 with a remainder of 183.
The number 7 becomes the next digit in our result. 
Result so far: 257.0
If we take 2709 away from 2892, we end up with 183.
Include the next digit (7) from the dividend after 183, then repeat: 1837 / 387

Step 6:
If we divide 1837 by 387, we get 4 and a remainder of 289.
Put 4 as the next digit of the answer. 
Result so far: 2574.0
If we subtract 1548 from 1837, we get 289.
Append the next digit (4) from the dividend to 289 and continue with: 2894 / 387

Advancing to step 7:
387 goes into 2894 7 times with a remainder of 185.
The number 7 becomes the next digit in our result. 
Result so far: 25747.0
Deduct 2709 from 2894 and we're left with 185.
Take the next digit (0) from the dividend and append it to 185, then repeat: 1850 / 387

Let's proceed to step 8:
When dividing 1850 by 387, we get 4 with a remainder of 302.
Write down 4 as next digit of the result. 
Result so far: 257474.0
Deduct 1548 from 1850 and we're left with 302.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3020, and continue the process.

On to step 9:
If we divide 3020 by 387, we get 7 and a remainder of 311.
Use 7 as the next digit of our solution. 
Result so far: 257474.7
Deduct 2709 from 3020 and we're left with 311.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3110, and continue the process.

On to step 10:
The number 387 fits into 3110 8 times, leaving a remainder of 14.
Put 8 as the next digit of the answer. 
Result so far: 257474.78
If we subtract 3096 from 3110, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 11:
When dividing 140 by 387, we get 0 with a remainder of 140.
Write down 0 as next digit of the result. 
Result so far: 257474.78
Subtract 0 from 140 to get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

On to step 12:
387 can be fit into 1400 3 times, resulting in a remainder of 239.
The number 3 becomes the next digit in our result. 
Result so far: 257474.7803
Subtracting 1161 from 1400 leaves us with 239.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2390, and continue the process.

Going ahead to step 13:
387 goes into 2390 6 times with a remainder of 68.
The next digit of our result is 6. 
Result so far: 257474.78036
Subtract 2322 from 2390 to get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Let's proceed to step 14:
680 divided by 387 is 1 with a remainder of 293.
Record the quotient 1 as the next digit in the result. 
Result so far: 257474.780361
Deduct 387 from 680 and we're left with 293.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2930, and continue the process.

Let's proceed to step 15:
2930 divided by 387 is 7 with a remainder of 221.
Record the quotient 7 as the next digit in the result. 
Result so far: 257474.7803617
If we subtract 2709 from 2930, we get 221.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2210, and continue the process.

Advancing to step 16:
387 goes into 2210 5 times with a remainder of 275.
The number 5 becomes the next digit in our result. 
Result so far: 257474.78036175
Subtract 1935 from 2210 to get 275.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

The quotient of the division is 257474.78036175, and the remainder is 2.75e-07.
