Let's divide 311989 by 51
We want to figure out the number of times 311989 can be divided by 51.

Moving on to step 1:
If we divide 3 by 51, we get 0 and a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Fetch the next digit (1) from the dividend, attach it to 3 and continue: 31 / 51

Moving on to step 2:
When dividing 31 by 51, we get 0 with a remainder of 31.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 31 and we're left with 31.
Grab the next digit (1) from the dividend, add it to 31, then carry on: 311 / 51

On to step 3:
If we divide 311 by 51, we get 6 and a remainder of 5.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
The remainder is 5 after subtracting 306 from 311.
Include the next digit (9) from the dividend after 5, then repeat: 59 / 51

Going ahead to step 4:
51 can be fit into 59 1 times, resulting in a remainder of 8.
Use 1 as the next digit of our solution. 
Result so far: 61.0
If we take 51 away from 59, we end up with 8.
Include the next digit (8) from the dividend after 8, then repeat: 88 / 51

Step 5:
If we divide 88 by 51, we get 1 and a remainder of 37.
Use 1 as the next digit of our solution. 
Result so far: 611.0
If we subtract 51 from 88, we get 37.
Append the next digit (9) from the dividend to 37 and continue with: 379 / 51

Step 6:
When dividing 379 by 51, we get 7 with a remainder of 22.
The next digit of our result is 7. 
Result so far: 6117.0
The remainder is 22 after subtracting 357 from 379.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 7:
220 divided by 51 is 4 with a remainder of 16.
Write down 4 as next digit of the result. 
Result so far: 6117.4
If we take 204 away from 220, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 8:
160 divided by 51 is 3 with a remainder of 7.
Put 3 as the next digit of the answer. 
Result so far: 6117.43
Subtract 153 from 160 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 9:
If we divide 70 by 51, we get 1 and a remainder of 19.
The next digit of our result is 1. 
Result so far: 6117.431
Deduct 51 from 70 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Advancing to step 10:
190 divided by 51 is 3 with a remainder of 37.
Write down 3 as next digit of the result. 
Result so far: 6117.4313
Deduct 153 from 190 and we're left with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Going ahead to step 11:
51 goes into 370 7 times with a remainder of 13.
Record the quotient 7 as the next digit in the result. 
Result so far: 6117.43137
If we take 357 away from 370, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 12:
The number 51 fits into 130 2 times, leaving a remainder of 28.
Put 2 as the next digit of the answer. 
Result so far: 6117.431372
If we subtract 102 from 130, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 13:
51 can be fit into 280 5 times, resulting in a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 6117.4313725
If we take 255 away from 280, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 14:
51 can be fit into 250 4 times, resulting in a remainder of 46.
Put 4 as the next digit of the answer. 
Result so far: 6117.43137254
Deduct 204 from 250 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

In conclusion, the division gives 6117.43137254 with a balance of 4.6e-08.
