89457649 ÷ 340 
Our goal is to divide 89457649 by 340.

Step 1:
340 can be fit into 8 0 times, resulting in a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Include the next digit (9) from the dividend after 8, then repeat: 89 / 340

On to step 2:
The number 340 fits into 89 0 times, leaving a remainder of 89.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 89 and we're left with 89.
Append the next digit (4) from the dividend to 89 and continue with: 894 / 340

Step 3:
340 can be fit into 894 2 times, resulting in a remainder of 214.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
The remainder is 214 after subtracting 680 from 894.
Fetch the next digit (5) from the dividend, attach it to 214 and continue: 2145 / 340

Let's proceed to step 4:
340 can be fit into 2145 6 times, resulting in a remainder of 105.
Record the quotient 6 as the next digit in the result. 
Result so far: 26.0
Subtracting 2040 from 2145 leaves us with 105.
Bring next digit (7) of the dividend behind the 105 and repeat the process: 1057 / 340

Moving on to step 5:
1057 divided by 340 is 3 with a remainder of 37.
The next digit of our result is 3. 
Result so far: 263.0
Deduct 1020 from 1057 and we're left with 37.
Grab the next digit (6) from the dividend, add it to 37, then carry on: 376 / 340

Moving on to step 6:
376 divided by 340 is 1 with a remainder of 36.
The number 1 becomes the next digit in our result. 
Result so far: 2631.0
The remainder is 36 after subtracting 340 from 376.
Take the next digit (4) from the dividend and append it to 36, then repeat: 364 / 340

Going ahead to step 7:
The number 340 fits into 364 1 times, leaving a remainder of 24.
Put 1 as the next digit of the answer. 
Result so far: 26311.0
Deduct 340 from 364 and we're left with 24.
Bring next digit (9) of the dividend behind the 24 and repeat the process: 249 / 340

Advancing to step 8:
340 can be fit into 249 0 times, resulting in a remainder of 249.
Use 0 as the next digit of our solution. 
Result so far: 263110.0
Subtracting 0 from 249 leaves us with 249.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2490, and continue the process.

Let's proceed to step 9:
When dividing 2490 by 340, we get 7 with a remainder of 110.
Put 7 as the next digit of the answer. 
Result so far: 263110.7
If we subtract 2380 from 2490, we get 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Moving on to step 10:
When dividing 1100 by 340, we get 3 with a remainder of 80.
The next digit of our result is 3. 
Result so far: 263110.73
If we subtract 1020 from 1100, we 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.

On to step 11:
When dividing 800 by 340, we get 2 with a remainder of 120.
Put 2 as the next digit of the answer. 
Result so far: 263110.732
If we subtract 680 from 800, 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.

Advancing to step 12:
340 can be fit into 1200 3 times, resulting in a remainder of 180.
The number 3 becomes the next digit in our result. 
Result so far: 263110.7323
Deduct 1020 from 1200 and we're left 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.

Advancing to step 13:
340 goes into 1800 5 times with a remainder of 100.
Put 5 as the next digit of the answer. 
Result so far: 263110.73235
The remainder is 100 after subtracting 1700 from 1800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

On to step 14:
1000 divided by 340 is 2 with a remainder of 320.
The number 2 becomes the next digit in our result. 
Result so far: 263110.732352
Subtract 680 from 1000 to get 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Moving on to step 15:
340 can be fit into 3200 9 times, resulting in a remainder of 140.
Put 9 as the next digit of the answer. 
Result so far: 263110.7323529
If we subtract 3060 from 3200, we get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Step 16:
If we divide 1400 by 340, we get 4 and a remainder of 40.
Put 4 as the next digit of the answer. 
Result so far: 263110.73235294
Subtract 1360 from 1400 to 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.

After the division, we end up with 263110.73235294 and a remainder of 4e-08.
