51761566 ÷ 213 
Our goal is to divide 51761566 by 213.

Advancing to step 1:
213 can be fit into 5 0 times, resulting in a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Grab the next digit (1) from the dividend, add it to 5, then carry on: 51 / 213

Going ahead to step 2:
When dividing 51 by 213, we get 0 with a remainder of 51.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 51 to get 51.
Include the next digit (7) from the dividend after 51, then repeat: 517 / 213

Step 3:
213 can be fit into 517 2 times, resulting in a remainder of 91.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we subtract 426 from 517, we get 91.
Fetch the next digit (6) from the dividend, attach it to 91 and continue: 916 / 213

Going ahead to step 4:
When dividing 916 by 213, we get 4 with a remainder of 64.
The next digit of our result is 4. 
Result so far: 24.0
Deduct 852 from 916 and we're left with 64.
Fetch the next digit (1) from the dividend, attach it to 64 and continue: 641 / 213

Advancing to step 5:
213 goes into 641 3 times with a remainder of 2.
The next digit of our result is 3. 
Result so far: 243.0
Deduct 639 from 641 and we're left with 2.
Bring next digit (5) of the dividend behind the 2 and repeat the process: 25 / 213

Step 6:
The number 213 fits into 25 0 times, leaving a remainder of 25.
Record the quotient 0 as the next digit in the result. 
Result so far: 2430.0
Subtract 0 from 25 to get 25.
Grab the next digit (6) from the dividend, add it to 25, then carry on: 256 / 213

Let's proceed to step 7:
213 can be fit into 256 1 times, resulting in a remainder of 43.
Use 1 as the next digit of our solution. 
Result so far: 24301.0
Subtract 213 from 256 to get 43.
Bring next digit (6) of the dividend behind the 43 and repeat the process: 436 / 213

Going ahead to step 8:
If we divide 436 by 213, we get 2 and a remainder of 10.
The next digit of our result is 2. 
Result so far: 243012.0
Subtract 426 from 436 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 9:
When dividing 100 by 213, we get 0 with a remainder of 100.
Record the quotient 0 as the next digit in the result. 
Result so far: 243012.0
The remainder is 100 after subtracting 0 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

On to step 10:
If we divide 1000 by 213, we get 4 and a remainder of 148.
Use 4 as the next digit of our solution. 
Result so far: 243012.04
Deduct 852 from 1000 and we're left with 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Step 11:
213 can be fit into 1480 6 times, resulting in a remainder of 202.
The next digit of our result is 6. 
Result so far: 243012.046
If we take 1278 away from 1480, we end up with 202.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

Going ahead to step 12:
213 goes into 2020 9 times with a remainder of 103.
The next digit of our result is 9. 
Result so far: 243012.0469
If we take 1917 away from 2020, we end up with 103.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1030, and continue the process.

Step 13:
213 can be fit into 1030 4 times, resulting in a remainder of 178.
Record the quotient 4 as the next digit in the result. 
Result so far: 243012.04694
If we subtract 852 from 1030, we get 178.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1780, and continue the process.

Let's proceed to step 14:
213 can be fit into 1780 8 times, resulting in a remainder of 76.
The number 8 becomes the next digit in our result. 
Result so far: 243012.046948
Deduct 1704 from 1780 and we're left with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Going ahead to step 15:
213 can be fit into 760 3 times, resulting in a remainder of 121.
The number 3 becomes the next digit in our result. 
Result so far: 243012.0469483
If we subtract 639 from 760, we get 121.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1210, and continue the process.

Let's proceed to step 16:
If we divide 1210 by 213, we get 5 and a remainder of 145.
Put 5 as the next digit of the answer. 
Result so far: 243012.04694835
If we subtract 1065 from 1210, we get 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

In conclusion, the division gives 243012.04694835 with a balance of 1.45e-07.
