We divide 66628451 by 621
We're looking to find how many times 621 goes into 66628451.

Step 1:
The number 621 fits into 6 0 times, leaving a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 621

Going ahead to step 2:
If we divide 66 by 621, we get 0 and a remainder of 66.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 66 after subtracting 0 from 66.
Include the next digit (6) from the dividend after 66, then repeat: 666 / 621

Let's proceed to step 3:
When dividing 666 by 621, we get 1 with a remainder of 45.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 621 away from 666, we end up with 45.
Bring next digit (2) of the dividend behind the 45 and repeat the process: 452 / 621

Let's proceed to step 4:
If we divide 452 by 621, we get 0 and a remainder of 452.
The next digit of our result is 0. 
Result so far: 10.0
Subtract 0 from 452 to get 452.
Grab the next digit (8) from the dividend, add it to 452, then carry on: 4528 / 621

Moving on to step 5:
4528 divided by 621 is 7 with a remainder of 181.
The next digit of our result is 7. 
Result so far: 107.0
Subtract 4347 from 4528 to get 181.
Fetch the next digit (4) from the dividend, attach it to 181 and continue: 1814 / 621

Advancing to step 6:
If we divide 1814 by 621, we get 2 and a remainder of 572.
Use 2 as the next digit of our solution. 
Result so far: 1072.0
The remainder is 572 after subtracting 1242 from 1814.
Take the next digit (5) from the dividend and append it to 572, then repeat: 5725 / 621

Let's proceed to step 7:
5725 divided by 621 is 9 with a remainder of 136.
Put 9 as the next digit of the answer. 
Result so far: 10729.0
The remainder is 136 after subtracting 5589 from 5725.
Take the next digit (1) from the dividend and append it to 136, then repeat: 1361 / 621

Moving on to step 8:
If we divide 1361 by 621, we get 2 and a remainder of 119.
The number 2 becomes the next digit in our result. 
Result so far: 107292.0
Deduct 1242 from 1361 and we're left with 119.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1190, and continue the process.

Moving on to step 9:
1190 divided by 621 is 1 with a remainder of 569.
Record the quotient 1 as the next digit in the result. 
Result so far: 107292.1
The remainder is 569 after subtracting 621 from 1190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5690, and continue the process.

Going ahead to step 10:
The number 621 fits into 5690 9 times, leaving a remainder of 101.
Write down 9 as next digit of the result. 
Result so far: 107292.19
Subtracting 5589 from 5690 leaves us with 101.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1010, and continue the process.

Moving on to step 11:
621 can be fit into 1010 1 times, resulting in a remainder of 389.
The number 1 becomes the next digit in our result. 
Result so far: 107292.191
Subtract 621 from 1010 to get 389.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3890, and continue the process.

Step 12:
621 can be fit into 3890 6 times, resulting in a remainder of 164.
Use 6 as the next digit of our solution. 
Result so far: 107292.1916
The remainder is 164 after subtracting 3726 from 3890.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Step 13:
If we divide 1640 by 621, we get 2 and a remainder of 398.
The next digit of our result is 2. 
Result so far: 107292.19162
Subtracting 1242 from 1640 leaves us with 398.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3980, and continue the process.

Going ahead to step 14:
If we divide 3980 by 621, we get 6 and a remainder of 254.
Use 6 as the next digit of our solution. 
Result so far: 107292.191626
If we take 3726 away from 3980, we end up 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.

Step 15:
621 can be fit into 2540 4 times, resulting in a remainder of 56.
Write down 4 as next digit of the result. 
Result so far: 107292.1916264
Deduct 2484 from 2540 and we're left with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Moving on to step 16:
560 divided by 621 is 0 with a remainder of 560.
Use 0 as the next digit of our solution. 
Result so far: 107292.1916264
If we take 0 away from 560, we end up with 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

The quotient of the division is 107292.1916264, and the remainder is 5.6e-07.
