47890021 ÷ 320 
We want to figure out the number of times 47890021 can be divided by 320.

Advancing to step 1:
When dividing 4 by 320, we get 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Append the next digit (7) from the dividend to 4 and continue with: 47 / 320

On to step 2:
320 goes into 47 0 times with a remainder of 47.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 47 to get 47.
Include the next digit (8) from the dividend after 47, then repeat: 478 / 320

Step 3:
320 goes into 478 1 times with a remainder of 158.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 320 from 478 to get 158.
Take the next digit (9) from the dividend and append it to 158, then repeat: 1589 / 320

Step 4:
When dividing 1589 by 320, we get 4 with a remainder of 309.
Write down 4 as next digit of the result. 
Result so far: 14.0
If we subtract 1280 from 1589, we get 309.
Include the next digit (0) from the dividend after 309, then repeat: 3090 / 320

Step 5:
3090 divided by 320 is 9 with a remainder of 210.
Write down 9 as next digit of the result. 
Result so far: 149.0
Subtracting 2880 from 3090 leaves us with 210.
Fetch the next digit (0) from the dividend, attach it to 210 and continue: 2100 / 320

Advancing to step 6:
When dividing 2100 by 320, we get 6 with a remainder of 180.
Use 6 as the next digit of our solution. 
Result so far: 1496.0
Subtract 1920 from 2100 to get 180.
Include the next digit (2) from the dividend after 180, then repeat: 1802 / 320

Going ahead to step 7:
1802 divided by 320 is 5 with a remainder of 202.
Record the quotient 5 as the next digit in the result. 
Result so far: 14965.0
If we take 1600 away from 1802, we end up with 202.
Include the next digit (1) from the dividend after 202, then repeat: 2021 / 320

On to step 8:
2021 divided by 320 is 6 with a remainder of 101.
Record the quotient 6 as the next digit in the result. 
Result so far: 149656.0
The remainder is 101 after subtracting 1920 from 2021.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1010, and continue the process.

Step 9:
The number 320 fits into 1010 3 times, leaving a remainder of 50.
The next digit of our result is 3. 
Result so far: 149656.3
Deduct 960 from 1010 and we're left with 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:
The number 320 fits into 500 1 times, leaving a remainder of 180.
Put 1 as the next digit of the answer. 
Result so far: 149656.31
If we subtract 320 from 500, we get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Let's proceed to step 11:
When dividing 1800 by 320, we get 5 with a remainder of 200.
Use 5 as the next digit of our solution. 
Result so far: 149656.315
If we subtract 1600 from 1800, we get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Step 12:
If we divide 2000 by 320, we get 6 and a remainder of 80.
Use 6 as the next digit of our solution. 
Result so far: 149656.3156
Subtracting 1920 from 2000 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 13:
800 divided by 320 is 2 with a remainder of 160.
Use 2 as the next digit of our solution. 
Result so far: 149656.31562
If we take 640 away from 800, we end up with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Step 14:
320 can be fit into 1600 5 times, resulting in a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 149656.315625
Deduct 1600 from 1600 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 15:
When dividing 0 by 320, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 149656.315625
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 16:
The number 320 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 149656.315625
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 149656.315625, with a leftover of 0.0.
