We divide 51621645 by 331
We're looking to find how many times 331 goes into 51621645.

Step 1:
If we divide 5 by 331, we get 0 and a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 331

Moving on to step 2:
When dividing 51 by 331, we get 0 with a remainder of 51.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 51 and we're left with 51.
Fetch the next digit (6) from the dividend, attach it to 51 and continue: 516 / 331

Going ahead to step 3:
331 goes into 516 1 times with a remainder of 185.
The next digit of our result is 1. 
Result so far: 1.0
If we take 331 away from 516, we end up with 185.
Bring next digit (2) of the dividend behind the 185 and repeat the process: 1852 / 331

Moving on to step 4:
331 goes into 1852 5 times with a remainder of 197.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
If we take 1655 away from 1852, we end up with 197.
Include the next digit (1) from the dividend after 197, then repeat: 1971 / 331

Step 5:
When dividing 1971 by 331, we get 5 with a remainder of 316.
Write down 5 as next digit of the result. 
Result so far: 155.0
If we subtract 1655 from 1971, we get 316.
Fetch the next digit (6) from the dividend, attach it to 316 and continue: 3166 / 331

Let's proceed to step 6:
3166 divided by 331 is 9 with a remainder of 187.
Write down 9 as next digit of the result. 
Result so far: 1559.0
Deduct 2979 from 3166 and we're left with 187.
Take the next digit (4) from the dividend and append it to 187, then repeat: 1874 / 331

On to step 7:
If we divide 1874 by 331, we get 5 and a remainder of 219.
The number 5 becomes the next digit in our result. 
Result so far: 15595.0
Subtract 1655 from 1874 to get 219.
Include the next digit (5) from the dividend after 219, then repeat: 2195 / 331

Moving on to step 8:
When dividing 2195 by 331, we get 6 with a remainder of 209.
The next digit of our result is 6. 
Result so far: 155956.0
If we take 1986 away from 2195, we end up 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 9:
If we divide 2090 by 331, we get 6 and a remainder of 104.
The number 6 becomes the next digit in our result. 
Result so far: 155956.6
If we subtract 1986 from 2090, we get 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Step 10:
If we divide 1040 by 331, we get 3 and a remainder of 47.
The number 3 becomes the next digit in our result. 
Result so far: 155956.63
If we subtract 993 from 1040, we get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

On to step 11:
331 goes into 470 1 times with a remainder of 139.
The number 1 becomes the next digit in our result. 
Result so far: 155956.631
The remainder is 139 after subtracting 331 from 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1390, and continue the process.

Step 12:
When dividing 1390 by 331, we get 4 with a remainder of 66.
The number 4 becomes the next digit in our result. 
Result so far: 155956.6314
If we take 1324 away from 1390, we end up with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Advancing to step 13:
331 goes into 660 1 times with a remainder of 329.
Write down 1 as next digit of the result. 
Result so far: 155956.63141
The remainder is 329 after subtracting 331 from 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3290, and continue the process.

Moving on to step 14:
When dividing 3290 by 331, we get 9 with a remainder of 311.
Write down 9 as next digit of the result. 
Result so far: 155956.631419
If we take 2979 away from 3290, we end up with 311.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3110, and continue the process.

Moving on to step 15:
The number 331 fits into 3110 9 times, leaving a remainder of 131.
The next digit of our result is 9. 
Result so far: 155956.6314199
The remainder is 131 after subtracting 2979 from 3110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1310, and continue the process.

Our division results in 155956.6314199 with a remaining 1.31e-06.
