45398821 divided by 873 
Let's see how many times 873 fits into 45398821.

Let's proceed to step 1:
When dividing 4 by 873, we get 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Bring next digit (5) of the dividend behind the 4 and repeat the process: 45 / 873

On to step 2:
When dividing 45 by 873, we get 0 with a remainder of 45.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 45, we get 45.
Fetch the next digit (3) from the dividend, attach it to 45 and continue: 453 / 873

Advancing to step 3:
873 can be fit into 453 0 times, resulting in a remainder of 453.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 453 and we're left with 453.
Take the next digit (9) from the dividend and append it to 453, then repeat: 4539 / 873

Going ahead to step 4:
4539 divided by 873 is 5 with a remainder of 174.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Subtract 4365 from 4539 to get 174.
Take the next digit (8) from the dividend and append it to 174, then repeat: 1748 / 873

Going ahead to step 5:
873 goes into 1748 2 times with a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 52.0
Deduct 1746 from 1748 and we're left with 2.
Take the next digit (8) from the dividend and append it to 2, then repeat: 28 / 873

Moving on to step 6:
873 can be fit into 28 0 times, resulting in a remainder of 28.
The next digit of our result is 0. 
Result so far: 520.0
The remainder is 28 after subtracting 0 from 28.
Take the next digit (2) from the dividend and append it to 28, then repeat: 282 / 873

Let's proceed to step 7:
873 goes into 282 0 times with a remainder of 282.
The next digit of our result is 0. 
Result so far: 5200.0
Deduct 0 from 282 and we're left with 282.
Bring next digit (1) of the dividend behind the 282 and repeat the process: 2821 / 873

Let's proceed to step 8:
873 goes into 2821 3 times with a remainder of 202.
Put 3 as the next digit of the answer. 
Result so far: 52003.0
If we take 2619 away from 2821, we end up with 202.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

Let's proceed to step 9:
873 goes into 2020 2 times with a remainder of 274.
Write down 2 as next digit of the result. 
Result so far: 52003.2
Deduct 1746 from 2020 and we're left with 274.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2740, and continue the process.

On to step 10:
When dividing 2740 by 873, we get 3 with a remainder of 121.
Use 3 as the next digit of our solution. 
Result so far: 52003.23
Subtract 2619 from 2740 to get 121.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1210, and continue the process.

Step 11:
When dividing 1210 by 873, we get 1 with a remainder of 337.
The next digit of our result is 1. 
Result so far: 52003.231
Subtract 873 from 1210 to get 337.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3370, and continue the process.

Step 12:
When dividing 3370 by 873, we get 3 with a remainder of 751.
Write down 3 as next digit of the result. 
Result so far: 52003.2313
Subtracting 2619 from 3370 leaves us with 751.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7510, and continue the process.

Moving on to step 13:
When dividing 7510 by 873, we get 8 with a remainder of 526.
Write down 8 as next digit of the result. 
Result so far: 52003.23138
Subtract 6984 from 7510 to get 526.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5260, and continue the process.

On to step 14:
If we divide 5260 by 873, we get 6 and a remainder of 22.
The number 6 becomes the next digit in our result. 
Result so far: 52003.231386
If we take 5238 away from 5260, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 15:
The number 873 fits into 220 0 times, leaving a remainder of 220.
Write down 0 as next digit of the result. 
Result so far: 52003.231386
Subtracting 0 from 220 leaves us 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.

Step 16:
When dividing 2200 by 873, we get 2 with a remainder of 454.
Write down 2 as next digit of the result. 
Result so far: 52003.23138602
Subtract 1746 from 2200 to get 454.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4540, and continue the process.

In conclusion, the division gives 52003.23138602 with a balance of 4.54e-07.
