97212854 divided by 669 
We want to figure out the number of times 97212854 can be divided by 669.

Moving on to step 1:
If we divide 9 by 669, we get 0 and a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Grab the next digit (7) from the dividend, add it to 9, then carry on: 97 / 669

Going ahead to step 2:
If we divide 97 by 669, we get 0 and a remainder of 97.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 97 leaves us with 97.
Fetch the next digit (2) from the dividend, attach it to 97 and continue: 972 / 669

Moving on to step 3:
The number 669 fits into 972 1 times, leaving a remainder of 303.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 669 from 972 and we're left with 303.
Append the next digit (1) from the dividend to 303 and continue with: 3031 / 669

Going ahead to step 4:
When dividing 3031 by 669, we get 4 with a remainder of 355.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
The remainder is 355 after subtracting 2676 from 3031.
Include the next digit (2) from the dividend after 355, then repeat: 3552 / 669

Let's proceed to step 5:
669 goes into 3552 5 times with a remainder of 207.
Put 5 as the next digit of the answer. 
Result so far: 145.0
The remainder is 207 after subtracting 3345 from 3552.
Include the next digit (8) from the dividend after 207, then repeat: 2078 / 669

On to step 6:
669 can be fit into 2078 3 times, resulting in a remainder of 71.
Use 3 as the next digit of our solution. 
Result so far: 1453.0
Deduct 2007 from 2078 and we're left with 71.
Take the next digit (5) from the dividend and append it to 71, then repeat: 715 / 669

Going ahead to step 7:
715 divided by 669 is 1 with a remainder of 46.
Put 1 as the next digit of the answer. 
Result so far: 14531.0
If we subtract 669 from 715, we get 46.
Fetch the next digit (4) from the dividend, attach it to 46 and continue: 464 / 669

On to step 8:
When dividing 464 by 669, we get 0 with a remainder of 464.
The next digit of our result is 0. 
Result so far: 145310.0
If we subtract 0 from 464, we get 464.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4640, and continue the process.

Advancing to step 9:
4640 divided by 669 is 6 with a remainder of 626.
The number 6 becomes the next digit in our result. 
Result so far: 145310.6
Subtracting 4014 from 4640 leaves us with 626.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6260, and continue the process.

Advancing to step 10:
If we divide 6260 by 669, we get 9 and a remainder of 239.
Write down 9 as next digit of the result. 
Result so far: 145310.69
If we subtract 6021 from 6260, we get 239.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2390, and continue the process.

On to step 11:
If we divide 2390 by 669, we get 3 and a remainder of 383.
Put 3 as the next digit of the answer. 
Result so far: 145310.693
Subtracting 2007 from 2390 leaves us with 383.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3830, and continue the process.

Going ahead to step 12:
When dividing 3830 by 669, we get 5 with a remainder of 485.
Put 5 as the next digit of the answer. 
Result so far: 145310.6935
Subtract 3345 from 3830 to get 485.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4850, and continue the process.

Advancing to step 13:
When dividing 4850 by 669, we get 7 with a remainder of 167.
Use 7 as the next digit of our solution. 
Result so far: 145310.69357
Subtract 4683 from 4850 to get 167.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1670, and continue the process.

Advancing to step 14:
If we divide 1670 by 669, we get 2 and a remainder of 332.
Put 2 as the next digit of the answer. 
Result so far: 145310.693572
Subtracting 1338 from 1670 leaves us with 332.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3320, and continue the process.

Step 15:
669 can be fit into 3320 4 times, resulting in a remainder of 644.
Write down 4 as next digit of the result. 
Result so far: 145310.6935724
Deduct 2676 from 3320 and we're left with 644.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6440, and continue the process.

Let's proceed to step 16:
669 can be fit into 6440 9 times, resulting in a remainder of 419.
The next digit of our result is 9. 
Result so far: 145310.69357249
The remainder is 419 after subtracting 6021 from 6440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4190, and continue the process.

After the division, we end up with 145310.69357249 and a remainder of 4.19e-07.
