If we take 0 away from 3, we end up with 3.
Take the next digit (1) from the dividend and append it to 3, then repeat: 31 / 453

Going ahead to step 2:
When dividing 31 by 453, we get 0 with a remainder of 31.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 31 after subtracting 0 from 31.
Append the next digit (1) from the dividend to 31 and continue with: 311 / 453

Going ahead to step 3:
When dividing 311 by 453, we get 0 with a remainder of 311.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 311, we end up with 311.
Bring next digit (2) of the dividend behind the 311 and repeat the process: 3112 / 453

Going ahead to step 4:
The number 453 fits into 3112 6 times, leaving a remainder of 394.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Subtract 2718 from 3112 to get 394.
Grab the next digit (3) from the dividend, add it to 394, then carry on: 3943 / 453

Advancing to step 5:
The number 453 fits into 3943 8 times, leaving a remainder of 319.
The number 8 becomes the next digit in our result. 
Result so far: 68.0
The remainder is 319 after subtracting 3624 from 3943.
Take the next digit (8) from the dividend and append it to 319, then repeat: 3198 / 453

Moving on to step 6:
When dividing 3198 by 453, we get 7 with a remainder of 27.
Use 7 as the next digit of our solution. 
Result so far: 687.0
If we take 3171 away from 3198, we end up with 27.
Fetch the next digit (6) from the dividend, attach it to 27 and continue: 276 / 453

Moving on to step 7:
453 can be fit into 276 0 times, resulting in a remainder of 276.
Record the quotient 0 as the next digit in the result. 
Result so far: 6870.0
Subtract 0 from 276 to get 276.
Take the next digit (4) from the dividend and append it to 276, then repeat: 2764 / 453

Step 8:
When dividing 2764 by 453, we get 6 with a remainder of 46.
Write down 6 as next digit of the result. 
Result so far: 68706.0
If we take 2718 away from 2764, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

On to step 9:
460 divided by 453 is 1 with a remainder of 7.
Record the quotient 1 as the next digit in the result. 
Result so far: 68706.1
The remainder is 7 after subtracting 453 from 460.
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 10:
The number 453 fits into 70 0 times, leaving a remainder of 70.
Use 0 as the next digit of our solution. 
Result so far: 68706.1
The remainder is 70 after subtracting 0 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Step 11:
When dividing 700 by 453, we get 1 with a remainder of 247.
Record the quotient 1 as the next digit in the result. 
Result so far: 68706.101
The remainder is 247 after subtracting 453 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2470, and continue the process.

Step 12:
If we divide 2470 by 453, we get 5 and a remainder of 205.
The number 5 becomes the next digit in our result. 
Result so far: 68706.1015
If we take 2265 away from 2470, we end up with 205.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

Advancing to step 13:
2050 divided by 453 is 4 with a remainder of 238.
Put 4 as the next digit of the answer. 
Result so far: 68706.10154
Subtract 1812 from 2050 to get 238.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

Step 14:
453 can be fit into 2380 5 times, resulting in a remainder of 115.
The number 5 becomes the next digit in our result. 
Result so far: 68706.101545
Deduct 2265 from 2380 and we're left with 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Advancing to step 15:
1150 divided by 453 is 2 with a remainder of 244.
The next digit of our result is 2. 
Result so far: 68706.1015452
Deduct 906 from 1150 and we're left with 244.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

Advancing to step 16:
453 can be fit into 2440 5 times, resulting in a remainder of 175.
The next digit of our result is 5. 
Result so far: 68706.10154525
Deduct 2265 from 2440 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 68706.10154525, and the remainder is 1.75e-07.
