We look at the division of 31866850 by 51 
We want to divide 31866850 by 51.

Step 1:
When dividing 3 by 51, we get 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Bring next digit (1) of the dividend behind the 3 and repeat the process: 31 / 51

Let's proceed to step 2:
The number 51 fits into 31 0 times, leaving a remainder of 31.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 31 to get 31.
Grab the next digit (8) from the dividend, add it to 31, then carry on: 318 / 51

Advancing to step 3:
If we divide 318 by 51, we get 6 and a remainder of 12.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
If we subtract 306 from 318, we get 12.
Bring next digit (6) of the dividend behind the 12 and repeat the process: 126 / 51

Step 4:
If we divide 126 by 51, we get 2 and a remainder of 24.
The next digit of our result is 2. 
Result so far: 62.0
If we subtract 102 from 126, we get 24.
Take the next digit (6) from the dividend and append it to 24, then repeat: 246 / 51

Going ahead to step 5:
If we divide 246 by 51, we get 4 and a remainder of 42.
Put 4 as the next digit of the answer. 
Result so far: 624.0
Deduct 204 from 246 and we're left with 42.
Take the next digit (8) from the dividend and append it to 42, then repeat: 428 / 51

Advancing to step 6:
The number 51 fits into 428 8 times, leaving a remainder of 20.
The next digit of our result is 8. 
Result so far: 6248.0
Subtracting 408 from 428 leaves us with 20.
Take the next digit (5) from the dividend and append it to 20, then repeat: 205 / 51

Advancing to step 7:
The number 51 fits into 205 4 times, leaving a remainder of 1.
Record the quotient 4 as the next digit in the result. 
Result so far: 62484.0
If we take 204 away from 205, we end up with 1.
Include the next digit (0) from the dividend after 1, then repeat: 10 / 51

Going ahead to step 8:
51 goes into 10 0 times with a remainder of 10.
The next digit of our result is 0. 
Result so far: 624840.0
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 9:
51 goes into 100 1 times with a remainder of 49.
The next digit of our result is 1. 
Result so far: 624840.1
Deduct 51 from 100 and we're left with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Going ahead to step 10:
The number 51 fits into 490 9 times, leaving a remainder of 31.
Record the quotient 9 as the next digit in the result. 
Result so far: 624840.19
If we take 459 away from 490, we end up with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Moving on to step 11:
51 goes into 310 6 times with a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 624840.196
If we subtract 306 from 310, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 12:
51 goes into 40 0 times with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 624840.196
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 13:
If we divide 400 by 51, we get 7 and a remainder of 43.
Use 7 as the next digit of our solution. 
Result so far: 624840.19607
Subtract 357 from 400 to get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Let's proceed to step 14:
If we divide 430 by 51, we get 8 and a remainder of 22.
Write down 8 as next digit of the result. 
Result so far: 624840.196078
If we subtract 408 from 430, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 15:
51 goes into 220 4 times with a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 624840.1960784
Subtracting 204 from 220 leaves us 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.

Let's proceed to step 16:
51 can be fit into 160 3 times, resulting in a remainder of 7.
The number 3 becomes the next digit in our result. 
Result so far: 624840.19607843
Deduct 153 from 160 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

In conclusion, the division gives 624840.19607843 with a balance of 7e-09.
