We're dividing 731791 by 451 
We want to divide 731791 by 451.

Moving on to step 1:
The number 451 fits into 7 0 times, leaving a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Include the next digit (3) from the dividend after 7, then repeat: 73 / 451

Going ahead to step 2:
451 goes into 73 0 times with a remainder of 73.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 73 to get 73.
Bring next digit (1) of the dividend behind the 73 and repeat the process: 731 / 451

Going ahead to step 3:
If we divide 731 by 451, we get 1 and a remainder of 280.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 451 from 731 and we're left with 280.
Grab the next digit (7) from the dividend, add it to 280, then carry on: 2807 / 451

On to step 4:
The number 451 fits into 2807 6 times, leaving a remainder of 101.
Write down 6 as next digit of the result. 
Result so far: 16.0
If we subtract 2706 from 2807, we get 101.
Append the next digit (9) from the dividend to 101 and continue with: 1019 / 451

Advancing to step 5:
When dividing 1019 by 451, we get 2 with a remainder of 117.
Record the quotient 2 as the next digit in the result. 
Result so far: 162.0
Subtract 902 from 1019 to get 117.
Include the next digit (1) from the dividend after 117, then repeat: 1171 / 451

Moving on to step 6:
If we divide 1171 by 451, we get 2 and a remainder of 269.
The number 2 becomes the next digit in our result. 
Result so far: 1622.0
If we take 902 away from 1171, we end up with 269.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2690, and continue the process.

Advancing to step 7:
451 goes into 2690 5 times with a remainder of 435.
Put 5 as the next digit of the answer. 
Result so far: 1622.5
If we take 2255 away from 2690, we end up with 435.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4350, and continue the process.

Let's proceed to step 8:
If we divide 4350 by 451, we get 9 and a remainder of 291.
Record the quotient 9 as the next digit in the result. 
Result so far: 1622.59
If we subtract 4059 from 4350, we get 291.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2910, and continue the process.

Let's proceed to step 9:
451 can be fit into 2910 6 times, resulting in a remainder of 204.
Put 6 as the next digit of the answer. 
Result so far: 1622.596
The remainder is 204 after subtracting 2706 from 2910.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

Going ahead to step 10:
451 can be fit into 2040 4 times, resulting in a remainder of 236.
Record the quotient 4 as the next digit in the result. 
Result so far: 1622.5964
Subtracting 1804 from 2040 leaves us with 236.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

Moving on to step 11:
When dividing 2360 by 451, we get 5 with a remainder of 105.
Use 5 as the next digit of our solution. 
Result so far: 1622.59645
Subtract 2255 from 2360 to get 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

On to step 12:
When dividing 1050 by 451, we get 2 with a remainder of 148.
Record the quotient 2 as the next digit in the result. 
Result so far: 1622.596452
If we take 902 away from 1050, we end up with 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Let's proceed to step 13:
The number 451 fits into 1480 3 times, leaving a remainder of 127.
Record the quotient 3 as the next digit in the result. 
Result so far: 1622.5964523
If we take 1353 away from 1480, we end up with 127.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1270, and continue the process.

Let's proceed to step 14:
The number 451 fits into 1270 2 times, leaving a remainder of 368.
The next digit of our result is 2. 
Result so far: 1622.59645232
Deduct 902 from 1270 and we're left with 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

After the division, we end up with 1622.59645232 and a remainder of 3.68e-07.
