38691009 ÷ 661 
Let's see how many times 661 fits into 38691009.

Advancing to step 1:
661 can be fit into 3 0 times, resulting in a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Include the next digit (8) from the dividend after 3, then repeat: 38 / 661

Let's proceed to step 2:
When dividing 38 by 661, we get 0 with a remainder of 38.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 38 and we're left with 38.
Bring next digit (6) of the dividend behind the 38 and repeat the process: 386 / 661

Advancing to step 3:
386 divided by 661 is 0 with a remainder of 386.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 386 after subtracting 0 from 386.
Take the next digit (9) from the dividend and append it to 386, then repeat: 3869 / 661

Step 4:
661 can be fit into 3869 5 times, resulting in a remainder of 564.
The next digit of our result is 5. 
Result so far: 5.0
Subtract 3305 from 3869 to get 564.
Bring next digit (1) of the dividend behind the 564 and repeat the process: 5641 / 661

Let's proceed to step 5:
5641 divided by 661 is 8 with a remainder of 353.
The number 8 becomes the next digit in our result. 
Result so far: 58.0
Subtract 5288 from 5641 to get 353.
Include the next digit (0) from the dividend after 353, then repeat: 3530 / 661

Advancing to step 6:
The number 661 fits into 3530 5 times, leaving a remainder of 225.
The next digit of our result is 5. 
Result so far: 585.0
Deduct 3305 from 3530 and we're left with 225.
Bring next digit (0) of the dividend behind the 225 and repeat the process: 2250 / 661

Moving on to step 7:
When dividing 2250 by 661, we get 3 with a remainder of 267.
Record the quotient 3 as the next digit in the result. 
Result so far: 5853.0
If we take 1983 away from 2250, we end up with 267.
Bring next digit (9) of the dividend behind the 267 and repeat the process: 2679 / 661

Let's proceed to step 8:
When dividing 2679 by 661, we get 4 with a remainder of 35.
The next digit of our result is 4. 
Result so far: 58534.0
If we take 2644 away from 2679, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 9:
When dividing 350 by 661, we get 0 with a remainder of 350.
Record the quotient 0 as the next digit in the result. 
Result so far: 58534.0
If we subtract 0 from 350, we get 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Moving on to step 10:
When dividing 3500 by 661, we get 5 with a remainder of 195.
Write down 5 as next digit of the result. 
Result so far: 58534.05
If we take 3305 away from 3500, we end up with 195.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

Advancing to step 11:
1950 divided by 661 is 2 with a remainder of 628.
Use 2 as the next digit of our solution. 
Result so far: 58534.052
If we take 1322 away from 1950, we end up with 628.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6280, and continue the process.

Going ahead to step 12:
6280 divided by 661 is 9 with a remainder of 331.
Write down 9 as next digit of the result. 
Result so far: 58534.0529
If we subtract 5949 from 6280, we get 331.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3310, and continue the process.

Let's proceed to step 13:
661 goes into 3310 5 times with a remainder of 5.
The next digit of our result is 5. 
Result so far: 58534.05295
If we subtract 3305 from 3310, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 14:
If we divide 50 by 661, we get 0 and a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 58534.05295
The remainder is 50 after subtracting 0 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 15:
661 goes into 500 0 times with a remainder of 500.
The number 0 becomes the next digit in our result. 
Result so far: 58534.05295
Subtract 0 from 500 to get 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

The final outcome is 58534.05295, with a leftover of 5e-06.
