70686158 ÷ 387 
We want to divide 70686158 by 387.

Step 1:
The number 387 fits into 7 0 times, leaving a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Include the next digit (0) from the dividend after 7, then repeat: 70 / 387

Moving on to step 2:
If we divide 70 by 387, we get 0 and a remainder of 70.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 70, we get 70.
Take the next digit (6) from the dividend and append it to 70, then repeat: 706 / 387

On to step 3:
The number 387 fits into 706 1 times, leaving a remainder of 319.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 387 away from 706, we end up with 319.
Bring next digit (8) of the dividend behind the 319 and repeat the process: 3198 / 387

Moving on to step 4:
If we divide 3198 by 387, we get 8 and a remainder of 102.
Write down 8 as next digit of the result. 
Result so far: 18.0
Subtract 3096 from 3198 to get 102.
Include the next digit (6) from the dividend after 102, then repeat: 1026 / 387

Advancing to step 5:
When dividing 1026 by 387, we get 2 with a remainder of 252.
Put 2 as the next digit of the answer. 
Result so far: 182.0
If we subtract 774 from 1026, we get 252.
Take the next digit (1) from the dividend and append it to 252, then repeat: 2521 / 387

Going ahead to step 6:
2521 divided by 387 is 6 with a remainder of 199.
Put 6 as the next digit of the answer. 
Result so far: 1826.0
Subtracting 2322 from 2521 leaves us with 199.
Include the next digit (5) from the dividend after 199, then repeat: 1995 / 387

Moving on to step 7:
387 can be fit into 1995 5 times, resulting in a remainder of 60.
Write down 5 as next digit of the result. 
Result so far: 18265.0
If we take 1935 away from 1995, we end up with 60.
Bring next digit (8) of the dividend behind the 60 and repeat the process: 608 / 387

Let's proceed to step 8:
When dividing 608 by 387, we get 1 with a remainder of 221.
The number 1 becomes the next digit in our result. 
Result so far: 182651.0
If we subtract 387 from 608, 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.

Let's proceed to step 9:
The number 387 fits into 2210 5 times, leaving a remainder of 275.
Write down 5 as next digit of the result. 
Result so far: 182651.5
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.

Step 10:
When dividing 2750 by 387, we get 7 with a remainder of 41.
Write down 7 as next digit of the result. 
Result so far: 182651.57
The remainder is 41 after subtracting 2709 from 2750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Let's proceed to step 11:
The number 387 fits into 410 1 times, leaving a remainder of 23.
Use 1 as the next digit of our solution. 
Result so far: 182651.571
If we take 387 away from 410, we end up 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.

Let's proceed to step 12:
387 can be fit into 230 0 times, resulting in a remainder of 230.
The number 0 becomes the next digit in our result. 
Result so far: 182651.571
The remainder is 230 after subtracting 0 from 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Moving on to step 13:
The number 387 fits into 2300 5 times, leaving a remainder of 365.
Write down 5 as next digit of the result. 
Result so far: 182651.57105
If we subtract 1935 from 2300, we get 365.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3650, and continue the process.

Advancing to step 14:
If we divide 3650 by 387, we get 9 and a remainder of 167.
Record the quotient 9 as the next digit in the result. 
Result so far: 182651.571059
Deduct 3483 from 3650 and we're left with 167.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1670, and continue the process.

Moving on to step 15:
387 can be fit into 1670 4 times, resulting in a remainder of 122.
The next digit of our result is 4. 
Result so far: 182651.5710594
Deduct 1548 from 1670 and we're left 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.

Let's proceed to step 16:
When dividing 1220 by 387, we get 3 with a remainder of 59.
Write down 3 as next digit of the result. 
Result so far: 182651.57105943
If we take 1161 away from 1220, we end up 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.

The quotient of the division is 182651.57105943, and the remainder is 5.9e-08.
