45938648 ÷ 490 
We want to divide 45938648 by 490.

Step 1:
4 divided by 490 is 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Append the next digit (5) from the dividend to 4 and continue with: 45 / 490

Moving on to step 2:
When dividing 45 by 490, we get 0 with a remainder of 45.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 45 and we're left with 45.
Include the next digit (9) from the dividend after 45, then repeat: 459 / 490

On to step 3:
If we divide 459 by 490, we get 0 and a remainder of 459.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 459 and we're left with 459.
Bring next digit (3) of the dividend behind the 459 and repeat the process: 4593 / 490

Let's proceed to step 4:
4593 divided by 490 is 9 with a remainder of 183.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Subtracting 4410 from 4593 leaves us with 183.
Grab the next digit (8) from the dividend, add it to 183, then carry on: 1838 / 490

Moving on to step 5:
490 can be fit into 1838 3 times, resulting in a remainder of 368.
Write down 3 as next digit of the result. 
Result so far: 93.0
Deduct 1470 from 1838 and we're left with 368.
Grab the next digit (6) from the dividend, add it to 368, then carry on: 3686 / 490

Let's proceed to step 6:
490 can be fit into 3686 7 times, resulting in a remainder of 256.
The number 7 becomes the next digit in our result. 
Result so far: 937.0
Subtracting 3430 from 3686 leaves us with 256.
Bring next digit (4) of the dividend behind the 256 and repeat the process: 2564 / 490

Let's proceed to step 7:
490 goes into 2564 5 times with a remainder of 114.
Put 5 as the next digit of the answer. 
Result so far: 9375.0
The remainder is 114 after subtracting 2450 from 2564.
Grab the next digit (8) from the dividend, add it to 114, then carry on: 1148 / 490

Step 8:
490 goes into 1148 2 times with a remainder of 168.
The next digit of our result is 2. 
Result so far: 93752.0
If we subtract 980 from 1148, we get 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Moving on to step 9:
1680 divided by 490 is 3 with a remainder of 210.
The next digit of our result is 3. 
Result so far: 93752.3
The remainder is 210 after subtracting 1470 from 1680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Moving on to step 10:
490 can be fit into 2100 4 times, resulting in a remainder of 140.
Write down 4 as next digit of the result. 
Result so far: 93752.34
Subtracting 1960 from 2100 leaves us with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Moving on to step 11:
490 goes into 1400 2 times with a remainder of 420.
The number 2 becomes the next digit in our result. 
Result so far: 93752.342
The remainder is 420 after subtracting 980 from 1400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Advancing to step 12:
When dividing 4200 by 490, we get 8 with a remainder of 280.
Put 8 as the next digit of the answer. 
Result so far: 93752.3428
If we subtract 3920 from 4200, we get 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Advancing to step 13:
490 can be fit into 2800 5 times, resulting in a remainder of 350.
The number 5 becomes the next digit in our result. 
Result so far: 93752.34285
Subtracting 2450 from 2800 leaves us with 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

On to step 14:
If we divide 3500 by 490, we get 7 and a remainder of 70.
Use 7 as the next digit of our solution. 
Result so far: 93752.342857
If we take 3430 away from 3500, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 15:
The number 490 fits into 700 1 times, leaving a remainder of 210.
Record the quotient 1 as the next digit in the result. 
Result so far: 93752.3428571
Deduct 490 from 700 and we're left with 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Advancing to step 16:
490 goes into 2100 4 times with a remainder of 140.
The number 4 becomes the next digit in our result. 
Result so far: 93752.34285714
Deduct 1960 from 2100 and we're left with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

In conclusion, the division gives 93752.34285714 with a balance of 1.4e-07.
