45015100 ÷ 373 
Our goal is to divide 45015100 by 373.

Going ahead to step 1:
The number 373 fits into 4 0 times, leaving a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Fetch the next digit (5) from the dividend, attach it to 4 and continue: 45 / 373

Going ahead to step 2:
When dividing 45 by 373, we get 0 with a remainder of 45.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 45, we get 45.
Append the next digit (0) from the dividend to 45 and continue with: 450 / 373

Advancing to step 3:
If we divide 450 by 373, we get 1 and a remainder of 77.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 373 from 450 and we're left with 77.
Bring next digit (1) of the dividend behind the 77 and repeat the process: 771 / 373

Advancing to step 4:
771 divided by 373 is 2 with a remainder of 25.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
The remainder is 25 after subtracting 746 from 771.
Include the next digit (5) from the dividend after 25, then repeat: 255 / 373

On to step 5:
If we divide 255 by 373, we get 0 and a remainder of 255.
The number 0 becomes the next digit in our result. 
Result so far: 120.0
The remainder is 255 after subtracting 0 from 255.
Fetch the next digit (1) from the dividend, attach it to 255 and continue: 2551 / 373

Let's proceed to step 6:
373 goes into 2551 6 times with a remainder of 313.
Put 6 as the next digit of the answer. 
Result so far: 1206.0
The remainder is 313 after subtracting 2238 from 2551.
Take the next digit (0) from the dividend and append it to 313, then repeat: 3130 / 373

Step 7:
3130 divided by 373 is 8 with a remainder of 146.
The next digit of our result is 8. 
Result so far: 12068.0
Subtracting 2984 from 3130 leaves us with 146.
Grab the next digit (0) from the dividend, add it to 146, then carry on: 1460 / 373

Step 8:
When dividing 1460 by 373, we get 3 with a remainder of 341.
The number 3 becomes the next digit in our result. 
Result so far: 120683.0
If we subtract 1119 from 1460, we get 341.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3410, and continue the process.

Moving on to step 9:
373 goes into 3410 9 times with a remainder of 53.
Put 9 as the next digit of the answer. 
Result so far: 120683.9
Subtracting 3357 from 3410 leaves us with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

On to step 10:
373 can be fit into 530 1 times, resulting in a remainder of 157.
The next digit of our result is 1. 
Result so far: 120683.91
Subtracting 373 from 530 leaves us with 157.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1570, and continue the process.

Step 11:
373 goes into 1570 4 times with a remainder of 78.
Record the quotient 4 as the next digit in the result. 
Result so far: 120683.914
If we take 1492 away from 1570, we end up with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Going ahead to step 12:
When dividing 780 by 373, we get 2 with a remainder of 34.
Use 2 as the next digit of our solution. 
Result so far: 120683.9142
Subtracting 746 from 780 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 13:
373 goes into 340 0 times with a remainder of 340.
Use 0 as the next digit of our solution. 
Result so far: 120683.9142
If we take 0 away from 340, we end up with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Moving on to step 14:
3400 divided by 373 is 9 with a remainder of 43.
Put 9 as the next digit of the answer. 
Result so far: 120683.914209
If we subtract 3357 from 3400, we 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.

On to step 15:
When dividing 430 by 373, we get 1 with a remainder of 57.
Put 1 as the next digit of the answer. 
Result so far: 120683.9142091
Subtract 373 from 430 to get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Let's proceed to step 16:
373 goes into 570 1 times with a remainder of 197.
Put 1 as the next digit of the answer. 
Result so far: 120683.91420911
Subtracting 373 from 570 leaves us with 197.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1970, and continue the process.

In conclusion, the division gives 120683.91420911 with a balance of 1.97e-07.
