851039 ÷ 75 
We're looking to find how many times 75 goes into 851039.

Advancing to step 1:
If we divide 8 by 75, we get 0 and a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Grab the next digit (5) from the dividend, add it to 8, then carry on: 85 / 75

On to step 2:
85 divided by 75 is 1 with a remainder of 10.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 75 from 85 to get 10.
Grab the next digit (1) from the dividend, add it to 10, then carry on: 101 / 75

On to step 3:
The number 75 fits into 101 1 times, leaving a remainder of 26.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
If we take 75 away from 101, we end up with 26.
Grab the next digit (0) from the dividend, add it to 26, then carry on: 260 / 75

Let's proceed to step 4:
When dividing 260 by 75, we get 3 with a remainder of 35.
The number 3 becomes the next digit in our result. 
Result so far: 113.0
If we take 225 away from 260, we end up with 35.
Include the next digit (3) from the dividend after 35, then repeat: 353 / 75

Step 5:
75 can be fit into 353 4 times, resulting in a remainder of 53.
Put 4 as the next digit of the answer. 
Result so far: 1134.0
If we take 300 away from 353, we end up with 53.
Append the next digit (9) from the dividend to 53 and continue with: 539 / 75

Let's proceed to step 6:
75 can be fit into 539 7 times, resulting in a remainder of 14.
Write down 7 as next digit of the result. 
Result so far: 11347.0
If we take 525 away from 539, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 7:
The number 75 fits into 140 1 times, leaving a remainder of 65.
Put 1 as the next digit of the answer. 
Result so far: 11347.1
Subtract 75 from 140 to get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Advancing to step 8:
75 can be fit into 650 8 times, resulting in a remainder of 50.
The next digit of our result is 8. 
Result so far: 11347.18
Subtracting 600 from 650 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 9:
When dividing 500 by 75, we get 6 with a remainder of 50.
Use 6 as the next digit of our solution. 
Result so far: 11347.186
Subtract 450 from 500 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 10:
75 goes into 500 6 times with a remainder of 50.
The number 6 becomes the next digit in our result. 
Result so far: 11347.1866
Subtract 450 from 500 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

The final result is 11347.1866 with a remainder of 0.0005.
