Let's divide 66940398 by 451
We want to divide 66940398 by 451.

On to step 1:
6 divided by 451 is 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 451

Going ahead to step 2:
66 divided by 451 is 0 with a remainder of 66.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 66 leaves us with 66.
Include the next digit (9) from the dividend after 66, then repeat: 669 / 451

On to step 3:
669 divided by 451 is 1 with a remainder of 218.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 451 from 669 to get 218.
Include the next digit (4) from the dividend after 218, then repeat: 2184 / 451

On to step 4:
If we divide 2184 by 451, we get 4 and a remainder of 380.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
Subtract 1804 from 2184 to get 380.
Fetch the next digit (0) from the dividend, attach it to 380 and continue: 3800 / 451

Going ahead to step 5:
The number 451 fits into 3800 8 times, leaving a remainder of 192.
The number 8 becomes the next digit in our result. 
Result so far: 148.0
Subtract 3608 from 3800 to get 192.
Bring next digit (3) of the dividend behind the 192 and repeat the process: 1923 / 451

Let's proceed to step 6:
The number 451 fits into 1923 4 times, leaving a remainder of 119.
Put 4 as the next digit of the answer. 
Result so far: 1484.0
If we subtract 1804 from 1923, we get 119.
Include the next digit (9) from the dividend after 119, then repeat: 1199 / 451

On to step 7:
1199 divided by 451 is 2 with a remainder of 297.
Record the quotient 2 as the next digit in the result. 
Result so far: 14842.0
The remainder is 297 after subtracting 902 from 1199.
Include the next digit (8) from the dividend after 297, then repeat: 2978 / 451

Going ahead to step 8:
The number 451 fits into 2978 6 times, leaving a remainder of 272.
The next digit of our result is 6. 
Result so far: 148426.0
If we subtract 2706 from 2978, we get 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

Going ahead to step 9:
451 goes into 2720 6 times with a remainder of 14.
Record the quotient 6 as the next digit in the result. 
Result so far: 148426.6
If we subtract 2706 from 2720, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 10:
When dividing 140 by 451, we get 0 with a remainder of 140.
Record the quotient 0 as the next digit in the result. 
Result so far: 148426.6
If we take 0 away from 140, we end up with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Let's proceed to step 11:
If we divide 1400 by 451, we get 3 and a remainder of 47.
The next digit of our result is 3. 
Result so far: 148426.603
Subtracting 1353 from 1400 leaves us with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Moving on to step 12:
When dividing 470 by 451, we get 1 with a remainder of 19.
The number 1 becomes the next digit in our result. 
Result so far: 148426.6031
If we subtract 451 from 470, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 13:
451 goes into 190 0 times with a remainder of 190.
Record the quotient 0 as the next digit in the result. 
Result so far: 148426.6031
If we take 0 away from 190, we end up with 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

On to step 14:
If we divide 1900 by 451, we get 4 and a remainder of 96.
The next digit of our result is 4. 
Result so far: 148426.603104
If we take 1804 away from 1900, we end up with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Moving on to step 15:
451 can be fit into 960 2 times, resulting in a remainder of 58.
The next digit of our result is 2. 
Result so far: 148426.6031042
Subtracting 902 from 960 leaves us with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Let's proceed to step 16:
If we divide 580 by 451, we get 1 and a remainder of 129.
Write down 1 as next digit of the result. 
Result so far: 148426.60310421
Subtracting 451 from 580 leaves us with 129.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1290, and continue the process.

Our division results in 148426.60310421 with a remaining 1.29e-07.
