If we divide 214 by 461, we get 0 and a remainder of 214.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 214 to get 214.
Append the next digit (0) from the dividend to 214 and continue with: 2140 / 461

Step 4:
461 goes into 2140 4 times with a remainder of 296.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Subtract 1844 from 2140 to get 296.
Bring next digit (7) of the dividend behind the 296 and repeat the process: 2967 / 461

Let's proceed to step 5:
When dividing 2967 by 461, we get 6 with a remainder of 201.
The number 6 becomes the next digit in our result. 
Result so far: 46.0
Subtract 2766 from 2967 to get 201.
Include the next digit (8) from the dividend after 201, then repeat: 2018 / 461

Advancing to step 6:
The number 461 fits into 2018 4 times, leaving a remainder of 174.
Put 4 as the next digit of the answer. 
Result so far: 464.0
If we subtract 1844 from 2018, we get 174.
Bring next digit (5) of the dividend behind the 174 and repeat the process: 1745 / 461

Advancing to step 7:
1745 divided by 461 is 3 with a remainder of 362.
Record the quotient 3 as the next digit in the result. 
Result so far: 4643.0
If we subtract 1383 from 1745, we get 362.
Include the next digit (8) from the dividend after 362, then repeat: 3628 / 461

Moving on to step 8:
461 can be fit into 3628 7 times, resulting in a remainder of 401.
The number 7 becomes the next digit in our result. 
Result so far: 46437.0
Deduct 3227 from 3628 and we're left with 401.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4010, and continue the process.

Step 9:
The number 461 fits into 4010 8 times, leaving a remainder of 322.
Write down 8 as next digit of the result. 
Result so far: 46437.8
If we take 3688 away from 4010, we end up with 322.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3220, and continue the process.

Step 10:
When dividing 3220 by 461, we get 6 with a remainder of 454.
Use 6 as the next digit of our solution. 
Result so far: 46437.86
Deduct 2766 from 3220 and we're left with 454.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4540, and continue the process.

On to step 11:
The number 461 fits into 4540 9 times, leaving a remainder of 391.
Record the quotient 9 as the next digit in the result. 
Result so far: 46437.869
Deduct 4149 from 4540 and we're left with 391.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3910, and continue the process.

Advancing to step 12:
461 goes into 3910 8 times with a remainder of 222.
The number 8 becomes the next digit in our result. 
Result so far: 46437.8698
If we subtract 3688 from 3910, we get 222.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2220, and continue the process.

Step 13:
The number 461 fits into 2220 4 times, leaving a remainder of 376.
Record the quotient 4 as the next digit in the result. 
Result so far: 46437.86984
Subtract 1844 from 2220 to get 376.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

Step 14:
461 can be fit into 3760 8 times, resulting in a remainder of 72.
Record the quotient 8 as the next digit in the result. 
Result so far: 46437.869848
Subtract 3688 from 3760 to get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Advancing to step 15:
720 divided by 461 is 1 with a remainder of 259.
Record the quotient 1 as the next digit in the result. 
Result so far: 46437.8698481
Subtracting 461 from 720 leaves us with 259.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2590, and continue the process.

Advancing to step 16:
The number 461 fits into 2590 5 times, leaving a remainder of 285.
Use 5 as the next digit of our solution. 
Result so far: 46437.86984815
Deduct 2305 from 2590 and we're left with 285.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2850, and continue the process.

The final result is 46437.86984815 with a remainder of 2.85e-07.
