We're dividing 66769902 by 451 
We want to figure out the number of times 66769902 can be divided by 451.

Moving on to step 1:
The number 451 fits into 6 0 times, leaving a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 451

Step 2:
66 divided by 451 is 0 with a remainder of 66.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 66, we get 66.
Append the next digit (7) from the dividend to 66 and continue with: 667 / 451

On to step 3:
451 can be fit into 667 1 times, resulting in a remainder of 216.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 451 from 667, we get 216.
Append the next digit (6) from the dividend to 216 and continue with: 2166 / 451

Let's proceed to step 4:
2166 divided by 451 is 4 with a remainder of 362.
Put 4 as the next digit of the answer. 
Result so far: 14.0
The remainder is 362 after subtracting 1804 from 2166.
Bring next digit (9) of the dividend behind the 362 and repeat the process: 3629 / 451

Moving on to step 5:
3629 divided by 451 is 8 with a remainder of 21.
Write down 8 as next digit of the result. 
Result so far: 148.0
Subtract 3608 from 3629 to get 21.
Append the next digit (9) from the dividend to 21 and continue with: 219 / 451

Let's proceed to step 6:
219 divided by 451 is 0 with a remainder of 219.
Use 0 as the next digit of our solution. 
Result so far: 1480.0
If we take 0 away from 219, we end up with 219.
Append the next digit (0) from the dividend to 219 and continue with: 2190 / 451

Moving on to step 7:
2190 divided by 451 is 4 with a remainder of 386.
Write down 4 as next digit of the result. 
Result so far: 14804.0
If we subtract 1804 from 2190, we get 386.
Grab the next digit (2) from the dividend, add it to 386, then carry on: 3862 / 451

On to step 8:
451 goes into 3862 8 times with a remainder of 254.
Record the quotient 8 as the next digit in the result. 
Result so far: 148048.0
Subtracting 3608 from 3862 leaves us with 254.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2540, and continue the process.

Moving on to step 9:
451 goes into 2540 5 times with a remainder of 285.
The number 5 becomes the next digit in our result. 
Result so far: 148048.5
If we subtract 2255 from 2540, we get 285.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2850, and continue the process.

On to step 10:
The number 451 fits into 2850 6 times, leaving a remainder of 144.
Use 6 as the next digit of our solution. 
Result so far: 148048.56
If we subtract 2706 from 2850, we get 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Let's proceed to step 11:
If we divide 1440 by 451, we get 3 and a remainder of 87.
Put 3 as the next digit of the answer. 
Result so far: 148048.563
Subtract 1353 from 1440 to get 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Step 12:
When dividing 870 by 451, we get 1 with a remainder of 419.
The number 1 becomes the next digit in our result. 
Result so far: 148048.5631
Deduct 451 from 870 and we're left with 419.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4190, and continue the process.

Advancing to step 13:
The number 451 fits into 4190 9 times, leaving a remainder of 131.
Record the quotient 9 as the next digit in the result. 
Result so far: 148048.56319
If we subtract 4059 from 4190, we get 131.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1310, and continue the process.

Advancing to step 14:
When dividing 1310 by 451, we get 2 with a remainder of 408.
Write down 2 as next digit of the result. 
Result so far: 148048.563192
Deduct 902 from 1310 and we're left with 408.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4080, and continue the process.

Advancing to step 15:
When dividing 4080 by 451, we get 9 with a remainder of 21.
Use 9 as the next digit of our solution. 
Result so far: 148048.5631929
Subtracting 4059 from 4080 leaves us with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Going ahead to step 16:
If we divide 210 by 451, we get 0 and a remainder of 210.
Record the quotient 0 as the next digit in the result. 
Result so far: 148048.5631929
Subtract 0 from 210 to get 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

The quotient of the division is 148048.5631929, and the remainder is 2.1e-07.
