Let's divide 84172066 by 451
We want to figure out the number of times 84172066 can be divided by 451.

Let's proceed to step 1:
8 divided by 451 is 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Append the next digit (4) from the dividend to 8 and continue with: 84 / 451

Moving on to step 2:
451 goes into 84 0 times with a remainder of 84.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 84 and we're left with 84.
Include the next digit (1) from the dividend after 84, then repeat: 841 / 451

Moving on to step 3:
451 goes into 841 1 times with a remainder of 390.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 451 from 841 and we're left with 390.
Append the next digit (7) from the dividend to 390 and continue with: 3907 / 451

Moving on to step 4:
3907 divided by 451 is 8 with a remainder of 299.
Use 8 as the next digit of our solution. 
Result so far: 18.0
Deduct 3608 from 3907 and we're left with 299.
Bring next digit (2) of the dividend behind the 299 and repeat the process: 2992 / 451

Step 5:
2992 divided by 451 is 6 with a remainder of 286.
The next digit of our result is 6. 
Result so far: 186.0
Deduct 2706 from 2992 and we're left with 286.
Append the next digit (0) from the dividend to 286 and continue with: 2860 / 451

Advancing to step 6:
451 goes into 2860 6 times with a remainder of 154.
Use 6 as the next digit of our solution. 
Result so far: 1866.0
Subtracting 2706 from 2860 leaves us with 154.
Bring next digit (6) of the dividend behind the 154 and repeat the process: 1546 / 451

Going ahead to step 7:
The number 451 fits into 1546 3 times, leaving a remainder of 193.
Write down 3 as next digit of the result. 
Result so far: 18663.0
Subtract 1353 from 1546 to get 193.
Append the next digit (6) from the dividend to 193 and continue with: 1936 / 451

On to step 8:
When dividing 1936 by 451, we get 4 with a remainder of 132.
Put 4 as the next digit of the answer. 
Result so far: 186634.0
Deduct 1804 from 1936 and we're left with 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Step 9:
The number 451 fits into 1320 2 times, leaving a remainder of 418.
Record the quotient 2 as the next digit in the result. 
Result so far: 186634.2
Subtract 902 from 1320 to get 418.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4180, and continue the process.

On to step 10:
If we divide 4180 by 451, we get 9 and a remainder of 121.
The number 9 becomes the next digit in our result. 
Result so far: 186634.29
If we subtract 4059 from 4180, we get 121.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1210, and continue the process.

Going ahead to step 11:
451 goes into 1210 2 times with a remainder of 308.
Record the quotient 2 as the next digit in the result. 
Result so far: 186634.292
The remainder is 308 after subtracting 902 from 1210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

On to step 12:
The number 451 fits into 3080 6 times, leaving a remainder of 374.
Write down 6 as next digit of the result. 
Result so far: 186634.2926
Subtracting 2706 from 3080 leaves us with 374.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3740, and continue the process.

Step 13:
The number 451 fits into 3740 8 times, leaving a remainder of 132.
Use 8 as the next digit of our solution. 
Result so far: 186634.29268
If we subtract 3608 from 3740, we get 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Let's proceed to step 14:
451 can be fit into 1320 2 times, resulting in a remainder of 418.
The number 2 becomes the next digit in our result. 
Result so far: 186634.292682
Subtract 902 from 1320 to get 418.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4180, and continue the process.

Step 15:
451 goes into 4180 9 times with a remainder of 121.
Use 9 as the next digit of our solution. 
Result so far: 186634.2926829
If we take 4059 away from 4180, we end up with 121.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1210, and continue the process.

Going ahead to step 16:
When dividing 1210 by 451, we get 2 with a remainder of 308.
Put 2 as the next digit of the answer. 
Result so far: 186634.29268292
If we subtract 902 from 1210, we get 308.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

After the division, we end up with 186634.29268292 and a remainder of 3.08e-07.
