We look at the division of 35651859 by 661 
We want to figure out the number of times 35651859 can be divided by 661.

Advancing to step 1:
The number 661 fits into 3 0 times, leaving a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Grab the next digit (5) from the dividend, add it to 3, then carry on: 35 / 661

Step 2:
The number 661 fits into 35 0 times, leaving a remainder of 35.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 35 to get 35.
Append the next digit (6) from the dividend to 35 and continue with: 356 / 661

Moving on to step 3:
661 can be fit into 356 0 times, resulting in a remainder of 356.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 356 after subtracting 0 from 356.
Take the next digit (5) from the dividend and append it to 356, then repeat: 3565 / 661

Step 4:
3565 divided by 661 is 5 with a remainder of 260.
Write down 5 as next digit of the result. 
Result so far: 5.0
If we subtract 3305 from 3565, we get 260.
Bring next digit (1) of the dividend behind the 260 and repeat the process: 2601 / 661

Advancing to step 5:
2601 divided by 661 is 3 with a remainder of 618.
Use 3 as the next digit of our solution. 
Result so far: 53.0
The remainder is 618 after subtracting 1983 from 2601.
Append the next digit (8) from the dividend to 618 and continue with: 6188 / 661

Moving on to step 6:
661 goes into 6188 9 times with a remainder of 239.
Put 9 as the next digit of the answer. 
Result so far: 539.0
Deduct 5949 from 6188 and we're left with 239.
Bring next digit (5) of the dividend behind the 239 and repeat the process: 2395 / 661

Advancing to step 7:
When dividing 2395 by 661, we get 3 with a remainder of 412.
Write down 3 as next digit of the result. 
Result so far: 5393.0
Subtracting 1983 from 2395 leaves us with 412.
Include the next digit (9) from the dividend after 412, then repeat: 4129 / 661

On to step 8:
661 goes into 4129 6 times with a remainder of 163.
Write down 6 as next digit of the result. 
Result so far: 53936.0
If we take 3966 away from 4129, we end up with 163.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1630, and continue the process.

Step 9:
If we divide 1630 by 661, we get 2 and a remainder of 308.
The next digit of our result is 2. 
Result so far: 53936.2
The remainder is 308 after subtracting 1322 from 1630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

Moving on to step 10:
661 can be fit into 3080 4 times, resulting in a remainder of 436.
Record the quotient 4 as the next digit in the result. 
Result so far: 53936.24
If we take 2644 away from 3080, we end up with 436.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4360, and continue the process.

Going ahead to step 11:
661 can be fit into 4360 6 times, resulting in a remainder of 394.
Put 6 as the next digit of the answer. 
Result so far: 53936.246
Deduct 3966 from 4360 and we're left with 394.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3940, and continue the process.

Step 12:
661 goes into 3940 5 times with a remainder of 635.
The next digit of our result is 5. 
Result so far: 53936.2465
Subtract 3305 from 3940 to get 635.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6350, and continue the process.

Let's proceed to step 13:
661 goes into 6350 9 times with a remainder of 401.
The next digit of our result is 9. 
Result so far: 53936.24659
If we take 5949 away from 6350, we end up with 401.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4010, and continue the process.

Going ahead to step 14:
When dividing 4010 by 661, we get 6 with a remainder of 44.
Put 6 as the next digit of the answer. 
Result so far: 53936.246596
If we subtract 3966 from 4010, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Moving on to step 15:
440 divided by 661 is 0 with a remainder of 440.
The number 0 becomes the next digit in our result. 
Result so far: 53936.246596
Subtracting 0 from 440 leaves us with 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Advancing to step 16:
4400 divided by 661 is 6 with a remainder of 434.
Use 6 as the next digit of our solution. 
Result so far: 53936.24659606
If we subtract 3966 from 4400, we get 434.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4340, and continue the process.

The final outcome is 53936.24659606, with a leftover of 4.34e-07.
