We look at the division of 97740631 by 661 
Our goal is to divide 97740631 by 661.

Moving on to step 1:
661 can be fit into 9 0 times, resulting in a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Take the next digit (7) from the dividend and append it to 9, then repeat: 97 / 661

Step 2:
If we divide 97 by 661, we get 0 and a remainder of 97.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 97 and we're left with 97.
Append the next digit (7) from the dividend to 97 and continue with: 977 / 661

Going ahead to step 3:
If we divide 977 by 661, we get 1 and a remainder of 316.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 661 from 977 to get 316.
Bring next digit (4) of the dividend behind the 316 and repeat the process: 3164 / 661

Going ahead to step 4:
If we divide 3164 by 661, we get 4 and a remainder of 520.
The next digit of our result is 4. 
Result so far: 14.0
Subtracting 2644 from 3164 leaves us with 520.
Take the next digit (0) from the dividend and append it to 520, then repeat: 5200 / 661

Advancing to step 5:
661 can be fit into 5200 7 times, resulting in a remainder of 573.
Put 7 as the next digit of the answer. 
Result so far: 147.0
If we take 4627 away from 5200, we end up with 573.
Bring next digit (6) of the dividend behind the 573 and repeat the process: 5736 / 661

Let's proceed to step 6:
If we divide 5736 by 661, we get 8 and a remainder of 448.
The number 8 becomes the next digit in our result. 
Result so far: 1478.0
Subtracting 5288 from 5736 leaves us with 448.
Take the next digit (3) from the dividend and append it to 448, then repeat: 4483 / 661

Moving on to step 7:
When dividing 4483 by 661, we get 6 with a remainder of 517.
Record the quotient 6 as the next digit in the result. 
Result so far: 14786.0
Deduct 3966 from 4483 and we're left with 517.
Bring next digit (1) of the dividend behind the 517 and repeat the process: 5171 / 661

On to step 8:
661 can be fit into 5171 7 times, resulting in a remainder of 544.
Use 7 as the next digit of our solution. 
Result so far: 147867.0
The remainder is 544 after subtracting 4627 from 5171.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5440, and continue the process.

Moving on to step 9:
When dividing 5440 by 661, we get 8 with a remainder of 152.
The next digit of our result is 8. 
Result so far: 147867.8
Subtracting 5288 from 5440 leaves us with 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Advancing to step 10:
When dividing 1520 by 661, we get 2 with a remainder of 198.
The next digit of our result is 2. 
Result so far: 147867.82
If we subtract 1322 from 1520, we get 198.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1980, and continue the process.

Advancing to step 11:
When dividing 1980 by 661, we get 2 with a remainder of 658.
Use 2 as the next digit of our solution. 
Result so far: 147867.822
The remainder is 658 after subtracting 1322 from 1980.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6580, and continue the process.

The final outcome is 147867.822, with a leftover of 0.0658.
