We look at the division of 98359811 by 661 
We want to figure out the number of times 98359811 can be divided by 661.

Moving on to step 1:
661 goes into 9 0 times with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Fetch the next digit (8) from the dividend, attach it to 9 and continue: 98 / 661

Going ahead to step 2:
The number 661 fits into 98 0 times, leaving a remainder of 98.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 98 and we're left with 98.
Include the next digit (3) from the dividend after 98, then repeat: 983 / 661

Moving on to step 3:
661 can be fit into 983 1 times, resulting in a remainder of 322.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 661 from 983 and we're left with 322.
Append the next digit (5) from the dividend to 322 and continue with: 3225 / 661

Let's proceed to step 4:
If we divide 3225 by 661, we get 4 and a remainder of 581.
Write down 4 as next digit of the result. 
Result so far: 14.0
Subtracting 2644 from 3225 leaves us with 581.
Grab the next digit (9) from the dividend, add it to 581, then carry on: 5819 / 661

Advancing to step 5:
661 goes into 5819 8 times with a remainder of 531.
Record the quotient 8 as the next digit in the result. 
Result so far: 148.0
Deduct 5288 from 5819 and we're left with 531.
Include the next digit (8) from the dividend after 531, then repeat: 5318 / 661

On to step 6:
661 can be fit into 5318 8 times, resulting in a remainder of 30.
Write down 8 as next digit of the result. 
Result so far: 1488.0
Subtract 5288 from 5318 to get 30.
Bring next digit (1) of the dividend behind the 30 and repeat the process: 301 / 661

Advancing to step 7:
When dividing 301 by 661, we get 0 with a remainder of 301.
Record the quotient 0 as the next digit in the result. 
Result so far: 14880.0
If we take 0 away from 301, we end up with 301.
Include the next digit (1) from the dividend after 301, then repeat: 3011 / 661

Advancing to step 8:
3011 divided by 661 is 4 with a remainder of 367.
The next digit of our result is 4. 
Result so far: 148804.0
Subtracting 2644 from 3011 leaves us with 367.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3670, and continue the process.

Advancing to step 9:
If we divide 3670 by 661, we get 5 and a remainder of 365.
The number 5 becomes the next digit in our result. 
Result so far: 148804.5
The remainder is 365 after subtracting 3305 from 3670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3650, and continue the process.

Moving on to step 10:
3650 divided by 661 is 5 with a remainder of 345.
Write down 5 as next digit of the result. 
Result so far: 148804.55
If we subtract 3305 from 3650, we get 345.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3450, and continue the process.

The final outcome is 148804.55, with a leftover of 0.345.
