We're dividing 75990384 by 170 
We're looking to find how many times 170 goes into 75990384.

Advancing to step 1:
When dividing 7 by 170, we get 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Bring next digit (5) of the dividend behind the 7 and repeat the process: 75 / 170

Advancing to step 2:
75 divided by 170 is 0 with a remainder of 75.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 75 after subtracting 0 from 75.
Take the next digit (9) from the dividend and append it to 75, then repeat: 759 / 170

Going ahead to step 3:
The number 170 fits into 759 4 times, leaving a remainder of 79.
The next digit of our result is 4. 
Result so far: 4.0
The remainder is 79 after subtracting 680 from 759.
Take the next digit (9) from the dividend and append it to 79, then repeat: 799 / 170

On to step 4:
The number 170 fits into 799 4 times, leaving a remainder of 119.
Use 4 as the next digit of our solution. 
Result so far: 44.0
If we subtract 680 from 799, we get 119.
Include the next digit (0) from the dividend after 119, then repeat: 1190 / 170

Going ahead to step 5:
170 can be fit into 1190 7 times, resulting in a remainder of 0.
Record the quotient 7 as the next digit in the result. 
Result so far: 447.0
Deduct 1190 from 1190 and we're left with 0.
Include the next digit (3) from the dividend after 0, then repeat: 3 / 170

Going ahead to step 6:
When dividing 3 by 170, we get 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 4470.0
The remainder is 3 after subtracting 0 from 3.
Bring next digit (8) of the dividend behind the 3 and repeat the process: 38 / 170

Advancing to step 7:
When dividing 38 by 170, we get 0 with a remainder of 38.
Use 0 as the next digit of our solution. 
Result so far: 44700.0
The remainder is 38 after subtracting 0 from 38.
Include the next digit (4) from the dividend after 38, then repeat: 384 / 170

On to step 8:
The number 170 fits into 384 2 times, leaving a remainder of 44.
Use 2 as the next digit of our solution. 
Result so far: 447002.0
If we take 340 away from 384, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Moving on to step 9:
When dividing 440 by 170, we get 2 with a remainder of 100.
Write down 2 as next digit of the result. 
Result so far: 447002.2
If we take 340 away from 440, we end up with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Advancing to step 10:
When dividing 1000 by 170, we get 5 with a remainder of 150.
The next digit of our result is 5. 
Result so far: 447002.25
The remainder is 150 after subtracting 850 from 1000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Going ahead to step 11:
170 can be fit into 1500 8 times, resulting in a remainder of 140.
Record the quotient 8 as the next digit in the result. 
Result so far: 447002.258
Subtracting 1360 from 1500 leaves us with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Moving on to step 12:
If we divide 1400 by 170, we get 8 and a remainder of 40.
Record the quotient 8 as the next digit in the result. 
Result so far: 447002.2588
Deduct 1360 from 1400 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

In conclusion, the division gives 447002.2588 with a balance of 0.0004.
