1687830 ÷ 361 
We want to figure out the number of times 1687830 can be divided by 361.

Let's proceed to step 1:
If we divide 1 by 361, we get 0 and a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Include the next digit (6) from the dividend after 1, then repeat: 16 / 361

Moving on to step 2:
The number 361 fits into 16 0 times, leaving a remainder of 16.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 16, we get 16.
Take the next digit (8) from the dividend and append it to 16, then repeat: 168 / 361

Step 3:
361 can be fit into 168 0 times, resulting in a remainder of 168.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 168, we get 168.
Bring next digit (7) of the dividend behind the 168 and repeat the process: 1687 / 361

Advancing to step 4:
The number 361 fits into 1687 4 times, leaving a remainder of 243.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtracting 1444 from 1687 leaves us with 243.
Fetch the next digit (8) from the dividend, attach it to 243 and continue: 2438 / 361

Let's proceed to step 5:
When dividing 2438 by 361, we get 6 with a remainder of 272.
The next digit of our result is 6. 
Result so far: 46.0
Subtracting 2166 from 2438 leaves us with 272.
Include the next digit (3) from the dividend after 272, then repeat: 2723 / 361

Let's proceed to step 6:
361 can be fit into 2723 7 times, resulting in a remainder of 196.
The number 7 becomes the next digit in our result. 
Result so far: 467.0
The remainder is 196 after subtracting 2527 from 2723.
Take the next digit (0) from the dividend and append it to 196, then repeat: 1960 / 361

Advancing to step 7:
When dividing 1960 by 361, we get 5 with a remainder of 155.
Write down 5 as next digit of the result. 
Result so far: 4675.0
If we take 1805 away from 1960, we end up with 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

Let's proceed to step 8:
When dividing 1550 by 361, we get 4 with a remainder of 106.
Record the quotient 4 as the next digit in the result. 
Result so far: 4675.4
Deduct 1444 from 1550 and we're left with 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Advancing to step 9:
The number 361 fits into 1060 2 times, leaving a remainder of 338.
The next digit of our result is 2. 
Result so far: 4675.42
Subtract 722 from 1060 to get 338.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3380, and continue the process.

Let's proceed to step 10:
When dividing 3380 by 361, we get 9 with a remainder of 131.
Write down 9 as next digit of the result. 
Result so far: 4675.429
Deduct 3249 from 3380 and we're left with 131.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1310, and continue the process.

Step 11:
361 goes into 1310 3 times with a remainder of 227.
The number 3 becomes the next digit in our result. 
Result so far: 4675.4293
If we subtract 1083 from 1310, we get 227.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2270, and continue the process.

Going ahead to step 12:
The number 361 fits into 2270 6 times, leaving a remainder of 104.
Put 6 as the next digit of the answer. 
Result so far: 4675.42936
If we take 2166 away from 2270, we end up with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Going ahead to step 13:
When dividing 1040 by 361, we get 2 with a remainder of 318.
Write down 2 as next digit of the result. 
Result so far: 4675.429362
The remainder is 318 after subtracting 722 from 1040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3180, and continue the process.

Advancing to step 14:
361 can be fit into 3180 8 times, resulting in a remainder of 292.
Record the quotient 8 as the next digit in the result. 
Result so far: 4675.4293628
If we take 2888 away from 3180, we end up with 292.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

Step 15:
The number 361 fits into 2920 8 times, leaving a remainder of 32.
Record the quotient 8 as the next digit in the result. 
Result so far: 4675.42936288
Subtract 2888 from 2920 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

In conclusion, the division gives 4675.42936288 with a balance of 3.2e-08.
