Let's divide 51218555 by 375
We're looking to find how many times 375 goes into 51218555.

Let's proceed to step 1:
375 goes into 5 0 times with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Grab the next digit (1) from the dividend, add it to 5, then carry on: 51 / 375

Let's proceed to step 2:
When dividing 51 by 375, we get 0 with a remainder of 51.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 51 leaves us with 51.
Take the next digit (2) from the dividend and append it to 51, then repeat: 512 / 375

Moving on to step 3:
When dividing 512 by 375, we get 1 with a remainder of 137.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 375 away from 512, we end up with 137.
Append the next digit (1) from the dividend to 137 and continue with: 1371 / 375

Let's proceed to step 4:
1371 divided by 375 is 3 with a remainder of 246.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
Subtracting 1125 from 1371 leaves us with 246.
Grab the next digit (8) from the dividend, add it to 246, then carry on: 2468 / 375

Moving on to step 5:
375 goes into 2468 6 times with a remainder of 218.
The next digit of our result is 6. 
Result so far: 136.0
If we take 2250 away from 2468, we end up with 218.
Fetch the next digit (5) from the dividend, attach it to 218 and continue: 2185 / 375

Let's proceed to step 6:
The number 375 fits into 2185 5 times, leaving a remainder of 310.
The number 5 becomes the next digit in our result. 
Result so far: 1365.0
The remainder is 310 after subtracting 1875 from 2185.
Take the next digit (5) from the dividend and append it to 310, then repeat: 3105 / 375

Going ahead to step 7:
The number 375 fits into 3105 8 times, leaving a remainder of 105.
Put 8 as the next digit of the answer. 
Result so far: 13658.0
The remainder is 105 after subtracting 3000 from 3105.
Take the next digit (5) from the dividend and append it to 105, then repeat: 1055 / 375

Let's proceed to step 8:
1055 divided by 375 is 2 with a remainder of 305.
The next digit of our result is 2. 
Result so far: 136582.0
If we subtract 750 from 1055, we get 305.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3050, and continue the process.

Step 9:
When dividing 3050 by 375, we get 8 with a remainder of 50.
Record the quotient 8 as the next digit in the result. 
Result so far: 136582.8
Subtract 3000 from 3050 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 10:
375 can be fit into 500 1 times, resulting in a remainder of 125.
Record the quotient 1 as the next digit in the result. 
Result so far: 136582.81
Subtract 375 from 500 to get 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Advancing to step 11:
The number 375 fits into 1250 3 times, leaving a remainder of 125.
The number 3 becomes the next digit in our result. 
Result so far: 136582.813
Subtract 1125 from 1250 to get 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Going ahead to step 12:
375 can be fit into 1250 3 times, resulting in a remainder of 125.
Write down 3 as next digit of the result. 
Result so far: 136582.8133
If we subtract 1125 from 1250, we get 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Our division results in 136582.8133 with a remaining 0.00125.
