We look at the division of 97972329 by 661 
We want to figure out the number of times 97972329 can be divided by 661.

Advancing to step 1:
661 can be fit into 9 0 times, resulting in a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Fetch the next digit (7) from the dividend, attach it to 9 and continue: 97 / 661

Advancing to step 2:
97 divided by 661 is 0 with a remainder of 97.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 97 and we're left with 97.
Grab the next digit (9) from the dividend, add it to 97, then carry on: 979 / 661

Going ahead to step 3:
If we divide 979 by 661, we get 1 and a remainder of 318.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 661 from 979 to get 318.
Take the next digit (7) from the dividend and append it to 318, then repeat: 3187 / 661

Going ahead to step 4:
The number 661 fits into 3187 4 times, leaving a remainder of 543.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
Deduct 2644 from 3187 and we're left with 543.
Fetch the next digit (2) from the dividend, attach it to 543 and continue: 5432 / 661

On to step 5:
When dividing 5432 by 661, we get 8 with a remainder of 144.
Put 8 as the next digit of the answer. 
Result so far: 148.0
If we subtract 5288 from 5432, we get 144.
Include the next digit (3) from the dividend after 144, then repeat: 1443 / 661

Advancing to step 6:
The number 661 fits into 1443 2 times, leaving a remainder of 121.
Record the quotient 2 as the next digit in the result. 
Result so far: 1482.0
If we take 1322 away from 1443, we end up with 121.
Include the next digit (2) from the dividend after 121, then repeat: 1212 / 661

On to step 7:
661 goes into 1212 1 times with a remainder of 551.
The next digit of our result is 1. 
Result so far: 14821.0
If we take 661 away from 1212, we end up with 551.
Take the next digit (9) from the dividend and append it to 551, then repeat: 5519 / 661

Going ahead to step 8:
When dividing 5519 by 661, we get 8 with a remainder of 231.
Write down 8 as next digit of the result. 
Result so far: 148218.0
If we take 5288 away from 5519, we end up with 231.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2310, and continue the process.

Going ahead to step 9:
2310 divided by 661 is 3 with a remainder of 327.
Put 3 as the next digit of the answer. 
Result so far: 148218.3
If we subtract 1983 from 2310, we get 327.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3270, and continue the process.

Step 10:
If we divide 3270 by 661, we get 4 and a remainder of 626.
Record the quotient 4 as the next digit in the result. 
Result so far: 148218.34
The remainder is 626 after subtracting 2644 from 3270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6260, and continue the process.

On to step 11:
When dividing 6260 by 661, we get 9 with a remainder of 311.
Record the quotient 9 as the next digit in the result. 
Result so far: 148218.349
If we take 5949 away from 6260, we end up with 311.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3110, and continue the process.

Advancing to step 12:
When dividing 3110 by 661, we get 4 with a remainder of 466.
Record the quotient 4 as the next digit in the result. 
Result so far: 148218.3494
Subtract 2644 from 3110 to get 466.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4660, and continue the process.

Going ahead to step 13:
The number 661 fits into 4660 7 times, leaving a remainder of 33.
Write down 7 as next digit of the result. 
Result so far: 148218.34947
If we take 4627 away from 4660, we end up with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

On to step 14:
If we divide 330 by 661, we get 0 and a remainder of 330.
Record the quotient 0 as the next digit in the result. 
Result so far: 148218.34947
The remainder is 330 after subtracting 0 from 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Moving on to step 15:
661 can be fit into 3300 4 times, resulting in a remainder of 656.
Write down 4 as next digit of the result. 
Result so far: 148218.3494704
If we subtract 2644 from 3300, we get 656.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6560, and continue the process.

Advancing to step 16:
661 can be fit into 6560 9 times, resulting in a remainder of 611.
Record the quotient 9 as the next digit in the result. 
Result so far: 148218.34947049
The remainder is 611 after subtracting 5949 from 6560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6110, and continue the process.

The final outcome is 148218.34947049, with a leftover of 6.11e-07.
