We look at the division of 31201452 by 451 
We want to divide 31201452 by 451.

On to step 1:
When dividing 3 by 451, we get 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Grab the next digit (1) from the dividend, add it to 3, then carry on: 31 / 451

Advancing to step 2:
When dividing 31 by 451, we get 0 with a remainder of 31.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 31, we end up with 31.
Append the next digit (2) from the dividend to 31 and continue with: 312 / 451

Let's proceed to step 3:
If we divide 312 by 451, we get 0 and a remainder of 312.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 312 to get 312.
Bring next digit (0) of the dividend behind the 312 and repeat the process: 3120 / 451

Let's proceed to step 4:
451 goes into 3120 6 times with a remainder of 414.
Use 6 as the next digit of our solution. 
Result so far: 6.0
If we subtract 2706 from 3120, we get 414.
Fetch the next digit (1) from the dividend, attach it to 414 and continue: 4141 / 451

Going ahead to step 5:
451 goes into 4141 9 times with a remainder of 82.
Use 9 as the next digit of our solution. 
Result so far: 69.0
Subtract 4059 from 4141 to get 82.
Grab the next digit (4) from the dividend, add it to 82, then carry on: 824 / 451

Advancing to step 6:
451 goes into 824 1 times with a remainder of 373.
Use 1 as the next digit of our solution. 
Result so far: 691.0
If we subtract 451 from 824, we get 373.
Take the next digit (5) from the dividend and append it to 373, then repeat: 3735 / 451

Advancing to step 7:
When dividing 3735 by 451, we get 8 with a remainder of 127.
Put 8 as the next digit of the answer. 
Result so far: 6918.0
Subtracting 3608 from 3735 leaves us with 127.
Bring next digit (2) of the dividend behind the 127 and repeat the process: 1272 / 451

Let's proceed to step 8:
The number 451 fits into 1272 2 times, leaving a remainder of 370.
Put 2 as the next digit of the answer. 
Result so far: 69182.0
Subtract 902 from 1272 to get 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

Advancing to step 9:
451 can be fit into 3700 8 times, resulting in a remainder of 92.
Put 8 as the next digit of the answer. 
Result so far: 69182.8
Deduct 3608 from 3700 and we're left with 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Moving on to step 10:
If we divide 920 by 451, we get 2 and a remainder of 18.
Write down 2 as next digit of the result. 
Result so far: 69182.82
Subtracting 902 from 920 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 11:
451 can be fit into 180 0 times, resulting in a remainder of 180.
Put 0 as the next digit of the answer. 
Result so far: 69182.82
Subtract 0 from 180 to get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Let's proceed to step 12:
If we divide 1800 by 451, we get 3 and a remainder of 447.
Write down 3 as next digit of the result. 
Result so far: 69182.8203
Subtract 1353 from 1800 to get 447.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4470, and continue the process.

Step 13:
451 goes into 4470 9 times with a remainder of 411.
Use 9 as the next digit of our solution. 
Result so far: 69182.82039
If we subtract 4059 from 4470, we get 411.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4110, and continue the process.

Advancing to step 14:
The number 451 fits into 4110 9 times, leaving a remainder of 51.
Put 9 as the next digit of the answer. 
Result so far: 69182.820399
If we subtract 4059 from 4110, we get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

The quotient of the division is 69182.820399, and the remainder is 5.1e-06.
