40371871 divided by 280 
Our goal is to divide 40371871 by 280.

Advancing to step 1:
280 goes into 4 0 times with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Fetch the next digit (0) from the dividend, attach it to 4 and continue: 40 / 280

Moving on to step 2:
If we divide 40 by 280, we get 0 and a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 40 to get 40.
Fetch the next digit (3) from the dividend, attach it to 40 and continue: 403 / 280

Moving on to step 3:
280 goes into 403 1 times with a remainder of 123.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 280 from 403, we get 123.
Fetch the next digit (7) from the dividend, attach it to 123 and continue: 1237 / 280

Let's proceed to step 4:
If we divide 1237 by 280, we get 4 and a remainder of 117.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
Subtracting 1120 from 1237 leaves us with 117.
Take the next digit (1) from the dividend and append it to 117, then repeat: 1171 / 280

On to step 5:
When dividing 1171 by 280, we get 4 with a remainder of 51.
The number 4 becomes the next digit in our result. 
Result so far: 144.0
Subtract 1120 from 1171 to get 51.
Grab the next digit (8) from the dividend, add it to 51, then carry on: 518 / 280

Step 6:
280 can be fit into 518 1 times, resulting in a remainder of 238.
Use 1 as the next digit of our solution. 
Result so far: 1441.0
The remainder is 238 after subtracting 280 from 518.
Take the next digit (7) from the dividend and append it to 238, then repeat: 2387 / 280

Going ahead to step 7:
2387 divided by 280 is 8 with a remainder of 147.
Record the quotient 8 as the next digit in the result. 
Result so far: 14418.0
If we subtract 2240 from 2387, we get 147.
Take the next digit (1) from the dividend and append it to 147, then repeat: 1471 / 280

Advancing to step 8:
When dividing 1471 by 280, we get 5 with a remainder of 71.
Put 5 as the next digit of the answer. 
Result so far: 144185.0
Subtracting 1400 from 1471 leaves us with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Moving on to step 9:
280 can be fit into 710 2 times, resulting in a remainder of 150.
Write down 2 as next digit of the result. 
Result so far: 144185.2
Deduct 560 from 710 and we're left with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Moving on to step 10:
When dividing 1500 by 280, we get 5 with a remainder of 100.
The number 5 becomes the next digit in our result. 
Result so far: 144185.25
If we take 1400 away from 1500, we end up with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Going ahead to step 11:
If we divide 1000 by 280, we get 3 and a remainder of 160.
Write down 3 as next digit of the result. 
Result so far: 144185.253
Subtracting 840 from 1000 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 12:
When dividing 1600 by 280, we get 5 with a remainder of 200.
Put 5 as the next digit of the answer. 
Result so far: 144185.2535
Subtract 1400 from 1600 to 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.

On to step 13:
The number 280 fits into 2000 7 times, leaving a remainder of 40.
Use 7 as the next digit of our solution. 
Result so far: 144185.25357
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.

On to step 14:
280 goes into 400 1 times with a remainder of 120.
The next digit of our result is 1. 
Result so far: 144185.253571
Subtracting 280 from 400 leaves us with 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 15:
When dividing 1200 by 280, we get 4 with a remainder of 80.
Put 4 as the next digit of the answer. 
Result so far: 144185.2535714
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.

On to step 16:
When dividing 800 by 280, we get 2 with a remainder of 240.
Record the quotient 2 as the next digit in the result. 
Result so far: 144185.25357142
The remainder is 240 after subtracting 560 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

After the division, we end up with 144185.25357142 and a remainder of 2.4e-07.
