372520 ÷ 51 
Let's see how many times 51 fits into 372520.

Let's proceed to step 1:
When dividing 3 by 51, we get 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Append the next digit (7) from the dividend to 3 and continue with: 37 / 51

Let's proceed to step 2:
The number 51 fits into 37 0 times, leaving a remainder of 37.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 37 leaves us with 37.
Grab the next digit (2) from the dividend, add it to 37, then carry on: 372 / 51

On to step 3:
The number 51 fits into 372 7 times, leaving a remainder of 15.
The next digit of our result is 7. 
Result so far: 7.0
If we take 357 away from 372, we end up with 15.
Grab the next digit (5) from the dividend, add it to 15, then carry on: 155 / 51

Moving on to step 4:
When dividing 155 by 51, we get 3 with a remainder of 2.
Put 3 as the next digit of the answer. 
Result so far: 73.0
Deduct 153 from 155 and we're left with 2.
Include the next digit (2) from the dividend after 2, then repeat: 22 / 51

Advancing to step 5:
51 goes into 22 0 times with a remainder of 22.
The next digit of our result is 0. 
Result so far: 730.0
If we subtract 0 from 22, we get 22.
Fetch the next digit (0) from the dividend, attach it to 22 and continue: 220 / 51

Let's proceed to step 6:
51 can be fit into 220 4 times, resulting in a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 7304.0
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 7:
If we divide 160 by 51, we get 3 and a remainder of 7.
Use 3 as the next digit of our solution. 
Result so far: 7304.3
If we subtract 153 from 160, we 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.

Going ahead to step 8:
51 can be fit into 70 1 times, resulting in a remainder of 19.
The next digit of our result is 1. 
Result so far: 7304.31
Subtracting 51 from 70 leaves us 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.

Let's proceed to step 9:
51 can be fit into 190 3 times, resulting in a remainder of 37.
Put 3 as the next digit of the answer. 
Result so far: 7304.313
If we take 153 away from 190, we end up 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.

On to step 10:
When dividing 370 by 51, we get 7 with a remainder of 13.
Record the quotient 7 as the next digit in the result. 
Result so far: 7304.3137
Deduct 357 from 370 and we're left 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.

Let's proceed to step 11:
If we divide 130 by 51, we get 2 and a remainder of 28.
Put 2 as the next digit of the answer. 
Result so far: 7304.31372
If we take 102 away from 130, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 12:
If we divide 280 by 51, we get 5 and a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 7304.313725
Subtract 255 from 280 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 13:
The number 51 fits into 250 4 times, leaving a remainder of 46.
The next digit of our result is 4. 
Result so far: 7304.3137254
Subtracting 204 from 250 leaves us 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.

Step 14:
460 divided by 51 is 9 with a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 7304.31372549
Subtract 459 from 460 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

The final result is 7304.31372549 with a remainder of 1e-09.
