445 can be fit into 3028 6 times, resulting in a remainder of 358.
The number 6 becomes the next digit in our result. 
Result so far: 116.0
If we subtract 2670 from 3028, we get 358.
Take the next digit (7) from the dividend and append it to 358, then repeat: 3587 / 445

Advancing to step 6:
The number 445 fits into 3587 8 times, leaving a remainder of 27.
Put 8 as the next digit of the answer. 
Result so far: 1168.0
If we subtract 3560 from 3587, we get 27.
Bring next digit (5) of the dividend behind the 27 and repeat the process: 275 / 445

Moving on to step 7:
When dividing 275 by 445, we get 0 with a remainder of 275.
Record the quotient 0 as the next digit in the result. 
Result so far: 11680.0
Deduct 0 from 275 and we're left with 275.
Fetch the next digit (3) from the dividend, attach it to 275 and continue: 2753 / 445

Moving on to step 8:
445 can be fit into 2753 6 times, resulting in a remainder of 83.
Use 6 as the next digit of our solution. 
Result so far: 116806.0
If we subtract 2670 from 2753, we get 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Let's proceed to step 9:
445 can be fit into 830 1 times, resulting in a remainder of 385.
The number 1 becomes the next digit in our result. 
Result so far: 116806.1
Subtract 445 from 830 to get 385.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3850, and continue the process.

Moving on to step 10:
445 can be fit into 3850 8 times, resulting in a remainder of 290.
Put 8 as the next digit of the answer. 
Result so far: 116806.18
If we subtract 3560 from 3850, we get 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Advancing to step 11:
445 goes into 2900 6 times with a remainder of 230.
The next digit of our result is 6. 
Result so far: 116806.186
Subtracting 2670 from 2900 leaves us with 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Step 12:
445 goes into 2300 5 times with a remainder of 75.
Record the quotient 5 as the next digit in the result. 
Result so far: 116806.1865
If we subtract 2225 from 2300, we get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Moving on to step 13:
When dividing 750 by 445, we get 1 with a remainder of 305.
The next digit of our result is 1. 
Result so far: 116806.18651
Subtract 445 from 750 to get 305.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3050, and continue the process.

Advancing to step 14:
445 can be fit into 3050 6 times, resulting in a remainder of 380.
The next digit of our result is 6. 
Result so far: 116806.186516
Subtracting 2670 from 3050 leaves us with 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Step 15:
3800 divided by 445 is 8 with a remainder of 240.
Write down 8 as next digit of the result. 
Result so far: 116806.1865168
Subtracting 3560 from 3800 leaves us with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

On to step 16:
445 goes into 2400 5 times with a remainder of 175.
Record the quotient 5 as the next digit in the result. 
Result so far: 116806.18651685
Deduct 2225 from 2400 and we're left with 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

The quotient of the division is 116806.18651685, and the remainder is 1.75e-07.
