78658264 ÷ 387 
We want to figure out the number of times 78658264 can be divided by 387.

On to step 1:
When dividing 7 by 387, we get 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 387

Going ahead to step 2:
387 can be fit into 78 0 times, resulting in a remainder of 78.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 78 and we're left with 78.
Include the next digit (6) from the dividend after 78, then repeat: 786 / 387

Moving on to step 3:
786 divided by 387 is 2 with a remainder of 12.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Deduct 774 from 786 and we're left with 12.
Bring next digit (5) of the dividend behind the 12 and repeat the process: 125 / 387

Moving on to step 4:
387 goes into 125 0 times with a remainder of 125.
Use 0 as the next digit of our solution. 
Result so far: 20.0
If we take 0 away from 125, we end up with 125.
Take the next digit (8) from the dividend and append it to 125, then repeat: 1258 / 387

Let's proceed to step 5:
The number 387 fits into 1258 3 times, leaving a remainder of 97.
The number 3 becomes the next digit in our result. 
Result so far: 203.0
The remainder is 97 after subtracting 1161 from 1258.
Include the next digit (2) from the dividend after 97, then repeat: 972 / 387

Let's proceed to step 6:
The number 387 fits into 972 2 times, leaving a remainder of 198.
The number 2 becomes the next digit in our result. 
Result so far: 2032.0
The remainder is 198 after subtracting 774 from 972.
Append the next digit (6) from the dividend to 198 and continue with: 1986 / 387

Advancing to step 7:
387 can be fit into 1986 5 times, resulting in a remainder of 51.
Use 5 as the next digit of our solution. 
Result so far: 20325.0
If we subtract 1935 from 1986, we get 51.
Include the next digit (4) from the dividend after 51, then repeat: 514 / 387

Advancing to step 8:
387 can be fit into 514 1 times, resulting in a remainder of 127.
The number 1 becomes the next digit in our result. 
Result so far: 203251.0
Deduct 387 from 514 and we're left with 127.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1270, and continue the process.

Moving on to step 9:
The number 387 fits into 1270 3 times, leaving a remainder of 109.
Write down 3 as next digit of the result. 
Result so far: 203251.3
If we take 1161 away from 1270, we end up with 109.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1090, and continue the process.

Step 10:
The number 387 fits into 1090 2 times, leaving a remainder of 316.
Put 2 as the next digit of the answer. 
Result so far: 203251.32
Subtract 774 from 1090 to get 316.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3160, and continue the process.

On to step 11:
3160 divided by 387 is 8 with a remainder of 64.
Write down 8 as next digit of the result. 
Result so far: 203251.328
If we subtract 3096 from 3160, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Advancing to step 12:
If we divide 640 by 387, we get 1 and a remainder of 253.
Put 1 as the next digit of the answer. 
Result so far: 203251.3281
Deduct 387 from 640 and we're left with 253.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2530, and continue the process.

On to step 13:
387 goes into 2530 6 times with a remainder of 208.
Record the quotient 6 as the next digit in the result. 
Result so far: 203251.32816
Subtract 2322 from 2530 to get 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Advancing to step 14:
The number 387 fits into 2080 5 times, leaving a remainder of 145.
Put 5 as the next digit of the answer. 
Result so far: 203251.328165
If we subtract 1935 from 2080, we get 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

Step 15:
387 can be fit into 1450 3 times, resulting in a remainder of 289.
Use 3 as the next digit of our solution. 
Result so far: 203251.3281653
If we take 1161 away from 1450, we end up with 289.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2890, and continue the process.

Step 16:
If we divide 2890 by 387, we get 7 and a remainder of 181.
Record the quotient 7 as the next digit in the result. 
Result so far: 203251.32816537
If we subtract 2709 from 2890, we get 181.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1810, and continue the process.

The quotient of the division is 203251.32816537, and the remainder is 1.81e-07.
