4505921 ÷ 381 
We want to figure out the number of times 4505921 can be divided by 381.

On to step 1:
When dividing 4 by 381, we get 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Include the next digit (5) from the dividend after 4, then repeat: 45 / 381

Advancing to step 2:
381 goes into 45 0 times with a remainder of 45.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 45 leaves us with 45.
Grab the next digit (0) from the dividend, add it to 45, then carry on: 450 / 381

Moving on to step 3:
450 divided by 381 is 1 with a remainder of 69.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 381 from 450, we get 69.
Append the next digit (5) from the dividend to 69 and continue with: 695 / 381

On to step 4:
381 can be fit into 695 1 times, resulting in a remainder of 314.
Put 1 as the next digit of the answer. 
Result so far: 11.0
If we take 381 away from 695, we end up with 314.
Grab the next digit (9) from the dividend, add it to 314, then carry on: 3149 / 381

Advancing to step 5:
The number 381 fits into 3149 8 times, leaving a remainder of 101.
The number 8 becomes the next digit in our result. 
Result so far: 118.0
If we take 3048 away from 3149, we end up with 101.
Take the next digit (2) from the dividend and append it to 101, then repeat: 1012 / 381

On to step 6:
1012 divided by 381 is 2 with a remainder of 250.
Record the quotient 2 as the next digit in the result. 
Result so far: 1182.0
If we subtract 762 from 1012, we get 250.
Bring next digit (1) of the dividend behind the 250 and repeat the process: 2501 / 381

Step 7:
381 goes into 2501 6 times with a remainder of 215.
The number 6 becomes the next digit in our result. 
Result so far: 11826.0
Deduct 2286 from 2501 and we're left with 215.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2150, and continue the process.

Moving on to step 8:
381 can be fit into 2150 5 times, resulting in a remainder of 245.
Record the quotient 5 as the next digit in the result. 
Result so far: 11826.5
If we subtract 1905 from 2150, we get 245.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2450, and continue the process.

Going ahead to step 9:
381 can be fit into 2450 6 times, resulting in a remainder of 164.
The number 6 becomes the next digit in our result. 
Result so far: 11826.56
Subtracting 2286 from 2450 leaves us with 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Step 10:
The number 381 fits into 1640 4 times, leaving a remainder of 116.
Write down 4 as next digit of the result. 
Result so far: 11826.564
Subtracting 1524 from 1640 leaves us with 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Moving on to step 11:
The number 381 fits into 1160 3 times, leaving a remainder of 17.
The number 3 becomes the next digit in our result. 
Result so far: 11826.5643
Subtracting 1143 from 1160 leaves us with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 12:
381 can be fit into 170 0 times, resulting in a remainder of 170.
Put 0 as the next digit of the answer. 
Result so far: 11826.5643
Subtract 0 from 170 to get 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Moving on to step 13:
When dividing 1700 by 381, we get 4 with a remainder of 176.
Write down 4 as next digit of the result. 
Result so far: 11826.564304
Subtract 1524 from 1700 to get 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Let's proceed to step 14:
381 goes into 1760 4 times with a remainder of 236.
The next digit of our result is 4. 
Result so far: 11826.5643044
If we take 1524 away from 1760, we end up with 236.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

The quotient of the division is 11826.5643044, and the remainder is 2.36e-06.
