We look at the division of 170399 by 76 
We want to divide 170399 by 76.

Step 1:
When dividing 1 by 76, we get 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Grab the next digit (7) from the dividend, add it to 1, then carry on: 17 / 76

On to step 2:
If we divide 17 by 76, we get 0 and a remainder of 17.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 17 and we're left with 17.
Grab the next digit (0) from the dividend, add it to 17, then carry on: 170 / 76

Step 3:
If we divide 170 by 76, we get 2 and a remainder of 18.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtract 152 from 170 to get 18.
Take the next digit (3) from the dividend and append it to 18, then repeat: 183 / 76

Advancing to step 4:
If we divide 183 by 76, we get 2 and a remainder of 31.
Use 2 as the next digit of our solution. 
Result so far: 22.0
The remainder is 31 after subtracting 152 from 183.
Append the next digit (9) from the dividend to 31 and continue with: 319 / 76

Going ahead to step 5:
The number 76 fits into 319 4 times, leaving a remainder of 15.
The number 4 becomes the next digit in our result. 
Result so far: 224.0
Subtracting 304 from 319 leaves us with 15.
Grab the next digit (9) from the dividend, add it to 15, then carry on: 159 / 76

Going ahead to step 6:
When dividing 159 by 76, we get 2 with a remainder of 7.
The number 2 becomes the next digit in our result. 
Result so far: 2242.0
Subtracting 152 from 159 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 7:
76 can be fit into 70 0 times, resulting in a remainder of 70.
The next digit of our result is 0. 
Result so far: 2242.0
If we subtract 0 from 70, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 8:
76 goes into 700 9 times with a remainder of 16.
The next digit of our result is 9. 
Result so far: 2242.09
Subtracting 684 from 700 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 9:
The number 76 fits into 160 2 times, leaving a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 2242.092
Deduct 152 from 160 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 10:
76 can be fit into 80 1 times, resulting in a remainder of 4.
The next digit of our result is 1. 
Result so far: 2242.0921
The remainder is 4 after subtracting 76 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 11:
When dividing 40 by 76, we get 0 with a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 2242.0921
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 12:
When dividing 400 by 76, we get 5 with a remainder of 20.
Write down 5 as next digit of the result. 
Result so far: 2242.092105
If we take 380 away from 400, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 13:
If we divide 200 by 76, we get 2 and a remainder of 48.
The number 2 becomes the next digit in our result. 
Result so far: 2242.0921052
The remainder is 48 after subtracting 152 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 14:
76 goes into 480 6 times with a remainder of 24.
The next digit of our result is 6. 
Result so far: 2242.09210526
If we subtract 456 from 480, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

The final result is 2242.09210526 with a remainder of 2.4e-08.
