Let's divide 55521643 by 212
We're looking to find how many times 212 goes into 55521643.

Step 1:
When dividing 5 by 212, we get 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
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 / 212

Advancing to step 2:
212 goes into 55 0 times with a remainder of 55.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 55, we get 55.
Fetch the next digit (5) from the dividend, attach it to 55 and continue: 555 / 212

Moving on to step 3:
555 divided by 212 is 2 with a remainder of 131.
The next digit of our result is 2. 
Result so far: 2.0
If we subtract 424 from 555, we get 131.
Append the next digit (2) from the dividend to 131 and continue with: 1312 / 212

On to step 4:
The number 212 fits into 1312 6 times, leaving a remainder of 40.
The next digit of our result is 6. 
Result so far: 26.0
If we subtract 1272 from 1312, we get 40.
Include the next digit (1) from the dividend after 40, then repeat: 401 / 212

Advancing to step 5:
401 divided by 212 is 1 with a remainder of 189.
Use 1 as the next digit of our solution. 
Result so far: 261.0
Deduct 212 from 401 and we're left with 189.
Fetch the next digit (6) from the dividend, attach it to 189 and continue: 1896 / 212

Advancing to step 6:
If we divide 1896 by 212, we get 8 and a remainder of 200.
Record the quotient 8 as the next digit in the result. 
Result so far: 2618.0
If we subtract 1696 from 1896, we get 200.
Bring next digit (4) of the dividend behind the 200 and repeat the process: 2004 / 212

Advancing to step 7:
2004 divided by 212 is 9 with a remainder of 96.
The number 9 becomes the next digit in our result. 
Result so far: 26189.0
The remainder is 96 after subtracting 1908 from 2004.
Include the next digit (3) from the dividend after 96, then repeat: 963 / 212

Advancing to step 8:
212 goes into 963 4 times with a remainder of 115.
Put 4 as the next digit of the answer. 
Result so far: 261894.0
If we take 848 away from 963, we end up with 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Step 9:
The number 212 fits into 1150 5 times, leaving a remainder of 90.
Put 5 as the next digit of the answer. 
Result so far: 261894.5
Subtract 1060 from 1150 to get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Advancing to step 10:
212 can be fit into 900 4 times, resulting in a remainder of 52.
The next digit of our result is 4. 
Result so far: 261894.54
Deduct 848 from 900 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

On to step 11:
212 goes into 520 2 times with a remainder of 96.
The number 2 becomes the next digit in our result. 
Result so far: 261894.542
Subtracting 424 from 520 leaves us with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Advancing to step 12:
When dividing 960 by 212, we get 4 with a remainder of 112.
Put 4 as the next digit of the answer. 
Result so far: 261894.5424
Deduct 848 from 960 and we're left with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Let's proceed to step 13:
212 can be fit into 1120 5 times, resulting in a remainder of 60.
Put 5 as the next digit of the answer. 
Result so far: 261894.54245
Deduct 1060 from 1120 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 14:
The number 212 fits into 600 2 times, leaving a remainder of 176.
The next digit of our result is 2. 
Result so far: 261894.542452
If we take 424 away from 600, we end up with 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Advancing to step 15:
212 goes into 1760 8 times with a remainder of 64.
The number 8 becomes the next digit in our result. 
Result so far: 261894.5424528
Subtract 1696 from 1760 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

On to step 16:
When dividing 640 by 212, we get 3 with a remainder of 4.
Use 3 as the next digit of our solution. 
Result so far: 261894.54245283
If we take 636 away from 640, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

After the division, we end up with 261894.54245283 and a remainder of 4e-09.
