78609463 ÷ 280 
We're looking to find how many times 280 goes into 78609463.

Step 1:
280 can be fit into 7 0 times, resulting in a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 280

Advancing to step 2:
78 divided by 280 is 0 with a remainder of 78.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 78 and we're left with 78.
Grab the next digit (6) from the dividend, add it to 78, then carry on: 786 / 280

Step 3:
The number 280 fits into 786 2 times, leaving a remainder of 226.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtract 560 from 786 to get 226.
Include the next digit (0) from the dividend after 226, then repeat: 2260 / 280

Going ahead to step 4:
If we divide 2260 by 280, we get 8 and a remainder of 20.
The next digit of our result is 8. 
Result so far: 28.0
Deduct 2240 from 2260 and we're left with 20.
Grab the next digit (9) from the dividend, add it to 20, then carry on: 209 / 280

Step 5:
When dividing 209 by 280, we get 0 with a remainder of 209.
Record the quotient 0 as the next digit in the result. 
Result so far: 280.0
If we subtract 0 from 209, we get 209.
Append the next digit (4) from the dividend to 209 and continue with: 2094 / 280

Advancing to step 6:
When dividing 2094 by 280, we get 7 with a remainder of 134.
The next digit of our result is 7. 
Result so far: 2807.0
If we take 1960 away from 2094, we end up with 134.
Append the next digit (6) from the dividend to 134 and continue with: 1346 / 280

Advancing to step 7:
280 goes into 1346 4 times with a remainder of 226.
The next digit of our result is 4. 
Result so far: 28074.0
If we subtract 1120 from 1346, we get 226.
Grab the next digit (3) from the dividend, add it to 226, then carry on: 2263 / 280

Moving on to step 8:
The number 280 fits into 2263 8 times, leaving a remainder of 23.
Put 8 as the next digit of the answer. 
Result so far: 280748.0
Subtract 2240 from 2263 to get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Moving on to step 9:
280 can be fit into 230 0 times, resulting in a remainder of 230.
The number 0 becomes the next digit in our result. 
Result so far: 280748.0
Subtracting 0 from 230 leaves us with 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Advancing to step 10:
The number 280 fits into 2300 8 times, leaving a remainder of 60.
The next digit of our result is 8. 
Result so far: 280748.08
If we take 2240 away from 2300, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 11:
If we divide 600 by 280, we get 2 and a remainder of 40.
Put 2 as the next digit of the answer. 
Result so far: 280748.082
If we take 560 away from 600, 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.

On to step 12:
280 goes into 400 1 times with a remainder of 120.
The next digit of our result is 1. 
Result so far: 280748.0821
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.

Going ahead to step 13:
When dividing 1200 by 280, we get 4 with a remainder of 80.
Use 4 as the next digit of our solution. 
Result so far: 280748.08214
Subtract 1120 from 1200 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 14:
280 goes into 800 2 times with a remainder of 240.
The next digit of our result is 2. 
Result so far: 280748.082142
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 15:
The number 280 fits into 2400 8 times, leaving a remainder of 160.
Write down 8 as next digit of the result. 
Result so far: 280748.0821428
Deduct 2240 from 2400 and we're left 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 16:
When dividing 1600 by 280, we get 5 with a remainder of 200.
The next digit of our result is 5. 
Result so far: 280748.08214285
Deduct 1400 from 1600 and we're left 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.

Our division results in 280748.08214285 with a remaining 2e-07.
