We're dividing 55043413 by 646 
We're looking to find how many times 646 goes into 55043413.

Moving on to step 1:
When dividing 5 by 646, we get 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Append the next digit (5) from the dividend to 5 and continue with: 55 / 646

Going ahead to step 2:
646 can be fit into 55 0 times, resulting in a remainder of 55.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 55 and we're left with 55.
Grab the next digit (0) from the dividend, add it to 55, then carry on: 550 / 646

Going ahead to step 3:
When dividing 550 by 646, we get 0 with a remainder of 550.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 550 to get 550.
Include the next digit (4) from the dividend after 550, then repeat: 5504 / 646

Moving on to step 4:
When dividing 5504 by 646, we get 8 with a remainder of 336.
Put 8 as the next digit of the answer. 
Result so far: 8.0
If we subtract 5168 from 5504, we get 336.
Include the next digit (3) from the dividend after 336, then repeat: 3363 / 646

On to step 5:
If we divide 3363 by 646, we get 5 and a remainder of 133.
The number 5 becomes the next digit in our result. 
Result so far: 85.0
Subtract 3230 from 3363 to get 133.
Take the next digit (4) from the dividend and append it to 133, then repeat: 1334 / 646

Advancing to step 6:
646 can be fit into 1334 2 times, resulting in a remainder of 42.
Write down 2 as next digit of the result. 
Result so far: 852.0
If we take 1292 away from 1334, we end up with 42.
Include the next digit (1) from the dividend after 42, then repeat: 421 / 646

Moving on to step 7:
646 can be fit into 421 0 times, resulting in a remainder of 421.
The next digit of our result is 0. 
Result so far: 8520.0
Subtract 0 from 421 to get 421.
Append the next digit (3) from the dividend to 421 and continue with: 4213 / 646

Advancing to step 8:
When dividing 4213 by 646, we get 6 with a remainder of 337.
The next digit of our result is 6. 
Result so far: 85206.0
Subtract 3876 from 4213 to get 337.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3370, and continue the process.

Let's proceed to step 9:
If we divide 3370 by 646, we get 5 and a remainder of 140.
Write down 5 as next digit of the result. 
Result so far: 85206.5
The remainder is 140 after subtracting 3230 from 3370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Moving on to step 10:
When dividing 1400 by 646, we get 2 with a remainder of 108.
Put 2 as the next digit of the answer. 
Result so far: 85206.52
Subtract 1292 from 1400 to get 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Step 11:
1080 divided by 646 is 1 with a remainder of 434.
Use 1 as the next digit of our solution. 
Result so far: 85206.521
The remainder is 434 after subtracting 646 from 1080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4340, and continue the process.

Let's proceed to step 12:
When dividing 4340 by 646, we get 6 with a remainder of 464.
The number 6 becomes the next digit in our result. 
Result so far: 85206.5216
The remainder is 464 after subtracting 3876 from 4340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4640, and continue the process.

Step 13:
646 goes into 4640 7 times with a remainder of 118.
Write down 7 as next digit of the result. 
Result so far: 85206.52167
If we subtract 4522 from 4640, we get 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

Advancing to step 14:
1180 divided by 646 is 1 with a remainder of 534.
Write down 1 as next digit of the result. 
Result so far: 85206.521671
If we take 646 away from 1180, we end up with 534.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5340, and continue the process.

Advancing to step 15:
The number 646 fits into 5340 8 times, leaving a remainder of 172.
The number 8 becomes the next digit in our result. 
Result so far: 85206.5216718
Subtracting 5168 from 5340 leaves us with 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

On to step 16:
When dividing 1720 by 646, we get 2 with a remainder of 428.
The number 2 becomes the next digit in our result. 
Result so far: 85206.52167182
Deduct 1292 from 1720 and we're left with 428.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4280, and continue the process.

The quotient of the division is 85206.52167182, and the remainder is 4.28e-07.
