We look at the division of 66318228 by 251 
We want to divide 66318228 by 251.

Step 1:
251 goes into 6 0 times with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 251

Advancing to step 2:
251 goes into 66 0 times with a remainder of 66.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 66 to get 66.
Take the next digit (3) from the dividend and append it to 66, then repeat: 663 / 251

On to step 3:
251 can be fit into 663 2 times, resulting in a remainder of 161.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtracting 502 from 663 leaves us with 161.
Bring next digit (1) of the dividend behind the 161 and repeat the process: 1611 / 251

Step 4:
The number 251 fits into 1611 6 times, leaving a remainder of 105.
Put 6 as the next digit of the answer. 
Result so far: 26.0
If we take 1506 away from 1611, we end up with 105.
Bring next digit (8) of the dividend behind the 105 and repeat the process: 1058 / 251

Moving on to step 5:
When dividing 1058 by 251, we get 4 with a remainder of 54.
Put 4 as the next digit of the answer. 
Result so far: 264.0
If we take 1004 away from 1058, we end up with 54.
Bring next digit (2) of the dividend behind the 54 and repeat the process: 542 / 251

Step 6:
If we divide 542 by 251, we get 2 and a remainder of 40.
Use 2 as the next digit of our solution. 
Result so far: 2642.0
Subtracting 502 from 542 leaves us with 40.
Fetch the next digit (2) from the dividend, attach it to 40 and continue: 402 / 251

On to step 7:
When dividing 402 by 251, we get 1 with a remainder of 151.
The next digit of our result is 1. 
Result so far: 26421.0
The remainder is 151 after subtracting 251 from 402.
Bring next digit (8) of the dividend behind the 151 and repeat the process: 1518 / 251

On to step 8:
251 can be fit into 1518 6 times, resulting in a remainder of 12.
Use 6 as the next digit of our solution. 
Result so far: 264216.0
If we take 1506 away from 1518, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 9:
251 can be fit into 120 0 times, resulting in a remainder of 120.
Use 0 as the next digit of our solution. 
Result so far: 264216.0
If we subtract 0 from 120, we get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Step 10:
1200 divided by 251 is 4 with a remainder of 196.
Use 4 as the next digit of our solution. 
Result so far: 264216.04
If we subtract 1004 from 1200, we get 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

Step 11:
1960 divided by 251 is 7 with a remainder of 203.
The number 7 becomes the next digit in our result. 
Result so far: 264216.047
If we subtract 1757 from 1960, we get 203.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2030, and continue the process.

Advancing to step 12:
2030 divided by 251 is 8 with a remainder of 22.
The next digit of our result is 8. 
Result so far: 264216.0478
Subtract 2008 from 2030 to 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.

Advancing to step 13:
251 can be fit into 220 0 times, resulting in a remainder of 220.
The next digit of our result is 0. 
Result so far: 264216.0478
If we take 0 away from 220, we end up with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Advancing to step 14:
2200 divided by 251 is 8 with a remainder of 192.
The next digit of our result is 8. 
Result so far: 264216.047808
If we subtract 2008 from 2200, we get 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Step 15:
If we divide 1920 by 251, we get 7 and a remainder of 163.
The number 7 becomes the next digit in our result. 
Result so far: 264216.0478087
Subtract 1757 from 1920 to get 163.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1630, and continue the process.

Moving on to step 16:
251 goes into 1630 6 times with a remainder of 124.
Put 6 as the next digit of the answer. 
Result so far: 264216.04780876
Subtract 1506 from 1630 to get 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

In conclusion, the division gives 264216.04780876 with a balance of 1.24e-07.
