51961957 ÷ 331 
We want to divide 51961957 by 331.

Going ahead to step 1:
331 can be fit into 5 0 times, resulting in a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Append the next digit (1) from the dividend to 5 and continue with: 51 / 331

Advancing to step 2:
When dividing 51 by 331, we get 0 with a remainder of 51.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 51, we end up with 51.
Fetch the next digit (9) from the dividend, attach it to 51 and continue: 519 / 331

Step 3:
If we divide 519 by 331, we get 1 and a remainder of 188.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 331 from 519 and we're left with 188.
Append the next digit (6) from the dividend to 188 and continue with: 1886 / 331

Let's proceed to step 4:
1886 divided by 331 is 5 with a remainder of 231.
Use 5 as the next digit of our solution. 
Result so far: 15.0
Deduct 1655 from 1886 and we're left with 231.
Bring next digit (1) of the dividend behind the 231 and repeat the process: 2311 / 331

Step 5:
2311 divided by 331 is 6 with a remainder of 325.
The number 6 becomes the next digit in our result. 
Result so far: 156.0
The remainder is 325 after subtracting 1986 from 2311.
Grab the next digit (9) from the dividend, add it to 325, then carry on: 3259 / 331

Moving on to step 6:
The number 331 fits into 3259 9 times, leaving a remainder of 280.
Use 9 as the next digit of our solution. 
Result so far: 1569.0
If we subtract 2979 from 3259, we get 280.
Bring next digit (5) of the dividend behind the 280 and repeat the process: 2805 / 331

Let's proceed to step 7:
When dividing 2805 by 331, we get 8 with a remainder of 157.
Write down 8 as next digit of the result. 
Result so far: 15698.0
The remainder is 157 after subtracting 2648 from 2805.
Append the next digit (7) from the dividend to 157 and continue with: 1577 / 331

Advancing to step 8:
When dividing 1577 by 331, we get 4 with a remainder of 253.
Write down 4 as next digit of the result. 
Result so far: 156984.0
If we subtract 1324 from 1577, we get 253.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2530, and continue the process.

On to step 9:
331 can be fit into 2530 7 times, resulting in a remainder of 213.
The number 7 becomes the next digit in our result. 
Result so far: 156984.7
Subtract 2317 from 2530 to get 213.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2130, and continue the process.

Step 10:
When dividing 2130 by 331, we get 6 with a remainder of 144.
The next digit of our result is 6. 
Result so far: 156984.76
The remainder is 144 after subtracting 1986 from 2130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Moving on to step 11:
331 goes into 1440 4 times with a remainder of 116.
Record the quotient 4 as the next digit in the result. 
Result so far: 156984.764
Deduct 1324 from 1440 and we're left with 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Going ahead to step 12:
331 can be fit into 1160 3 times, resulting in a remainder of 167.
The number 3 becomes the next digit in our result. 
Result so far: 156984.7643
Subtract 993 from 1160 to get 167.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1670, and continue the process.

Let's proceed to step 13:
If we divide 1670 by 331, we get 5 and a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 156984.76435
Subtract 1655 from 1670 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 14:
If we divide 150 by 331, we get 0 and a remainder of 150.
The next digit of our result is 0. 
Result so far: 156984.76435
Subtracting 0 from 150 leaves us with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

On to step 15:
331 goes into 1500 4 times with a remainder of 176.
Write down 4 as next digit of the result. 
Result so far: 156984.7643504
If we take 1324 away from 1500, 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.

Step 16:
When dividing 1760 by 331, we get 5 with a remainder of 105.
Put 5 as the next digit of the answer. 
Result so far: 156984.76435045
Subtract 1655 from 1760 to get 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

After the division, we end up with 156984.76435045 and a remainder of 1.05e-07.
