Let's divide 3742584 by 280
We want to figure out the number of times 3742584 can be divided by 280.

On to step 1:
The number 280 fits into 3 0 times, leaving a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Fetch the next digit (7) from the dividend, attach it to 3 and continue: 37 / 280

Advancing to step 2:
When dividing 37 by 280, we get 0 with a remainder of 37.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 37, we get 37.
Include the next digit (4) from the dividend after 37, then repeat: 374 / 280

Moving on to step 3:
The number 280 fits into 374 1 times, leaving a remainder of 94.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 280 from 374 and we're left with 94.
Fetch the next digit (2) from the dividend, attach it to 94 and continue: 942 / 280

Advancing to step 4:
When dividing 942 by 280, we get 3 with a remainder of 102.
Write down 3 as next digit of the result. 
Result so far: 13.0
The remainder is 102 after subtracting 840 from 942.
Grab the next digit (5) from the dividend, add it to 102, then carry on: 1025 / 280

Moving on to step 5:
280 can be fit into 1025 3 times, resulting in a remainder of 185.
Use 3 as the next digit of our solution. 
Result so far: 133.0
Deduct 840 from 1025 and we're left with 185.
Grab the next digit (8) from the dividend, add it to 185, then carry on: 1858 / 280

Let's proceed to step 6:
When dividing 1858 by 280, we get 6 with a remainder of 178.
Record the quotient 6 as the next digit in the result. 
Result so far: 1336.0
If we take 1680 away from 1858, we end up with 178.
Take the next digit (4) from the dividend and append it to 178, then repeat: 1784 / 280

On to step 7:
If we divide 1784 by 280, we get 6 and a remainder of 104.
Record the quotient 6 as the next digit in the result. 
Result so far: 13366.0
Subtracting 1680 from 1784 leaves us with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Step 8:
When dividing 1040 by 280, we get 3 with a remainder of 200.
Write down 3 as next digit of the result. 
Result so far: 13366.3
If we take 840 away from 1040, we end up with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Moving on to step 9:
When dividing 2000 by 280, we get 7 with a remainder of 40.
The next digit of our result is 7. 
Result so far: 13366.37
If we subtract 1960 from 2000, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 10:
If we divide 400 by 280, we get 1 and a remainder of 120.
The number 1 becomes the next digit in our result. 
Result so far: 13366.371
If we subtract 280 from 400, we get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Let's proceed to step 11:
The number 280 fits into 1200 4 times, leaving a remainder of 80.
Record the quotient 4 as the next digit in the result. 
Result so far: 13366.3714
Subtracting 1120 from 1200 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.

On to step 12:
If we divide 800 by 280, we get 2 and a remainder of 240.
The next digit of our result is 2. 
Result so far: 13366.37142
If we subtract 560 from 800, we get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

On to step 13:
The number 280 fits into 2400 8 times, leaving a remainder of 160.
Record the quotient 8 as the next digit in the result. 
Result so far: 13366.371428
If we take 2240 away from 2400, 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:
280 can be fit into 1600 5 times, resulting in a remainder of 200.
Put 5 as the next digit of the answer. 
Result so far: 13366.3714285
If we subtract 1400 from 1600, 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.

Let's proceed to step 15:
280 can be fit into 2000 7 times, resulting in a remainder of 40.
The next digit of our result is 7. 
Result so far: 13366.37142857
If we take 1960 away from 2000, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

The final result is 13366.37142857 with a remainder of 4e-08.
