We look at the division of 39907461 by 280 
We want to divide 39907461 by 280.

Step 1:
280 goes into 3 0 times with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 280

Let's proceed to step 2:
39 divided by 280 is 0 with a remainder of 39.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 39 leaves us with 39.
Grab the next digit (9) from the dividend, add it to 39, then carry on: 399 / 280

Advancing to step 3:
280 can be fit into 399 1 times, resulting in a remainder of 119.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 280 from 399, we get 119.
Take the next digit (0) from the dividend and append it to 119, then repeat: 1190 / 280

Advancing to step 4:
280 goes into 1190 4 times with a remainder of 70.
Use 4 as the next digit of our solution. 
Result so far: 14.0
If we take 1120 away from 1190, we end up with 70.
Take the next digit (7) from the dividend and append it to 70, then repeat: 707 / 280

Let's proceed to step 5:
707 divided by 280 is 2 with a remainder of 147.
Use 2 as the next digit of our solution. 
Result so far: 142.0
The remainder is 147 after subtracting 560 from 707.
Grab the next digit (4) from the dividend, add it to 147, then carry on: 1474 / 280

On to step 6:
When dividing 1474 by 280, we get 5 with a remainder of 74.
Record the quotient 5 as the next digit in the result. 
Result so far: 1425.0
If we subtract 1400 from 1474, we get 74.
Take the next digit (6) from the dividend and append it to 74, then repeat: 746 / 280

On to step 7:
When dividing 746 by 280, we get 2 with a remainder of 186.
Use 2 as the next digit of our solution. 
Result so far: 14252.0
If we take 560 away from 746, we end up with 186.
Take the next digit (1) from the dividend and append it to 186, then repeat: 1861 / 280

Going ahead to step 8:
If we divide 1861 by 280, we get 6 and a remainder of 181.
The number 6 becomes the next digit in our result. 
Result so far: 142526.0
If we take 1680 away from 1861, we end up with 181.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1810, and continue the process.

Advancing to step 9:
The number 280 fits into 1810 6 times, leaving a remainder of 130.
Write down 6 as next digit of the result. 
Result so far: 142526.6
Subtracting 1680 from 1810 leaves us with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Advancing to step 10:
When dividing 1300 by 280, we get 4 with a remainder of 180.
Put 4 as the next digit of the answer. 
Result so far: 142526.64
Subtracting 1120 from 1300 leaves us with 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:
The number 280 fits into 1800 6 times, leaving a remainder of 120.
Use 6 as the next digit of our solution. 
Result so far: 142526.646
The remainder is 120 after subtracting 1680 from 1800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Step 12:
1200 divided by 280 is 4 with a remainder of 80.
Record the quotient 4 as the next digit in the result. 
Result so far: 142526.6464
The remainder is 80 after subtracting 1120 from 1200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Advancing to step 13:
800 divided by 280 is 2 with a remainder of 240.
Write down 2 as next digit of the result. 
Result so far: 142526.64642
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.

Let's proceed to step 14:
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: 142526.646428
Subtracting 2240 from 2400 leaves us 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.

On to step 15:
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: 142526.6464285
The remainder is 200 after subtracting 1400 from 1600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Advancing to step 16:
If we divide 2000 by 280, we get 7 and a remainder of 40.
Use 7 as the next digit of our solution. 
Result so far: 142526.64642857
The remainder is 40 after subtracting 1960 from 2000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Our division results in 142526.64642857 with a remaining 4e-08.
