51078764 ÷ 231 
We want to divide 51078764 by 231.

On to step 1:
5 divided by 231 is 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 231

Advancing to step 2:
231 goes into 51 0 times with a remainder of 51.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 51 and we're left with 51.
Include the next digit (0) from the dividend after 51, then repeat: 510 / 231

Going ahead to step 3:
When dividing 510 by 231, we get 2 with a remainder of 48.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we subtract 462 from 510, we get 48.
Fetch the next digit (7) from the dividend, attach it to 48 and continue: 487 / 231

Moving on to step 4:
231 goes into 487 2 times with a remainder of 25.
Put 2 as the next digit of the answer. 
Result so far: 22.0
Subtracting 462 from 487 leaves us with 25.
Include the next digit (8) from the dividend after 25, then repeat: 258 / 231

Going ahead to step 5:
The number 231 fits into 258 1 times, leaving a remainder of 27.
The next digit of our result is 1. 
Result so far: 221.0
Subtract 231 from 258 to get 27.
Include the next digit (7) from the dividend after 27, then repeat: 277 / 231

Step 6:
231 goes into 277 1 times with a remainder of 46.
Use 1 as the next digit of our solution. 
Result so far: 2211.0
Deduct 231 from 277 and we're left with 46.
Fetch the next digit (6) from the dividend, attach it to 46 and continue: 466 / 231

Step 7:
If we divide 466 by 231, we get 2 and a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 22112.0
If we subtract 462 from 466, we get 4.
Fetch the next digit (4) from the dividend, attach it to 4 and continue: 44 / 231

Advancing to step 8:
If we divide 44 by 231, we get 0 and a remainder of 44.
Use 0 as the next digit of our solution. 
Result so far: 221120.0
If we subtract 0 from 44, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 9:
When dividing 440 by 231, we get 1 with a remainder of 209.
The next digit of our result is 1. 
Result so far: 221120.1
Deduct 231 from 440 and we're left with 209.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2090, and continue the process.

Step 10:
If we divide 2090 by 231, we get 9 and a remainder of 11.
The next digit of our result is 9. 
Result so far: 221120.19
If we subtract 2079 from 2090, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 11:
110 divided by 231 is 0 with a remainder of 110.
Write down 0 as next digit of the result. 
Result so far: 221120.19
Subtracting 0 from 110 leaves us with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Moving on to step 12:
If we divide 1100 by 231, we get 4 and a remainder of 176.
Use 4 as the next digit of our solution. 
Result so far: 221120.1904
Subtracting 924 from 1100 leaves us 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.

Step 13:
When dividing 1760 by 231, we get 7 with a remainder of 143.
The next digit of our result is 7. 
Result so far: 221120.19047
If we take 1617 away from 1760, we end up with 143.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1430, and continue the process.

Going ahead to step 14:
If we divide 1430 by 231, we get 6 and a remainder of 44.
Record the quotient 6 as the next digit in the result. 
Result so far: 221120.190476
If we take 1386 away from 1430, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Let's proceed to step 15:
231 goes into 440 1 times with a remainder of 209.
Use 1 as the next digit of our solution. 
Result so far: 221120.1904761
Subtract 231 from 440 to get 209.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2090, and continue the process.

Going ahead to step 16:
2090 divided by 231 is 9 with a remainder of 11.
Write down 9 as next digit of the result. 
Result so far: 221120.19047619
Subtract 2079 from 2090 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

After the division, we end up with 221120.19047619 and a remainder of 1.1e-08.
