353986 ÷ 55 
We want to figure out the number of times 353986 can be divided by 55.

Let's proceed to step 1:
When dividing 3 by 55, we get 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Take the next digit (5) from the dividend and append it to 3, then repeat: 35 / 55

Step 2:
The number 55 fits into 35 0 times, leaving a remainder of 35.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 35 and we're left with 35.
Fetch the next digit (3) from the dividend, attach it to 35 and continue: 353 / 55

Advancing to step 3:
The number 55 fits into 353 6 times, leaving a remainder of 23.
Write down 6 as next digit of the result. 
Result so far: 6.0
Subtracting 330 from 353 leaves us with 23.
Take the next digit (9) from the dividend and append it to 23, then repeat: 239 / 55

Advancing to step 4:
The number 55 fits into 239 4 times, leaving a remainder of 19.
The number 4 becomes the next digit in our result. 
Result so far: 64.0
Subtracting 220 from 239 leaves us with 19.
Take the next digit (8) from the dividend and append it to 19, then repeat: 198 / 55

Advancing to step 5:
55 can be fit into 198 3 times, resulting in a remainder of 33.
The number 3 becomes the next digit in our result. 
Result so far: 643.0
Subtract 165 from 198 to get 33.
Include the next digit (6) from the dividend after 33, then repeat: 336 / 55

Let's proceed to step 6:
When dividing 336 by 55, we get 6 with a remainder of 6.
Write down 6 as next digit of the result. 
Result so far: 6436.0
If we subtract 330 from 336, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 7:
The number 55 fits into 60 1 times, leaving a remainder of 5.
The next digit of our result is 1. 
Result so far: 6436.1
Subtracting 55 from 60 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 8:
55 goes into 50 0 times with a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 6436.1
Subtract 0 from 50 to get 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 9:
55 goes into 500 9 times with a remainder of 5.
Record the quotient 9 as the next digit in the result. 
Result so far: 6436.109
The remainder is 5 after subtracting 495 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 10:
The number 55 fits into 50 0 times, leaving a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 6436.109
Subtract 0 from 50 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 11:
When dividing 500 by 55, we get 9 with a remainder of 5.
Put 9 as the next digit of the answer. 
Result so far: 6436.10909
If we subtract 495 from 500, 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.

Going ahead to step 12:
The number 55 fits into 50 0 times, leaving a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 6436.10909
Subtracting 0 from 50 leaves us with 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 13:
500 divided by 55 is 9 with a remainder of 5.
Put 9 as the next digit of the answer. 
Result so far: 6436.1090909
If we subtract 495 from 500, 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:
55 can be fit into 50 0 times, resulting in a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 6436.1090909
If we subtract 0 from 50, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

The final outcome is 6436.1090909, with a leftover of 5e-08.
