80531564 divided by 340 
We want to figure out the number of times 80531564 can be divided by 340.

Let's proceed to step 1:
If we divide 8 by 340, we get 0 and a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Append the next digit (0) from the dividend to 8 and continue with: 80 / 340

Step 2:
When dividing 80 by 340, we get 0 with a remainder of 80.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 80 to get 80.
Bring next digit (5) of the dividend behind the 80 and repeat the process: 805 / 340

Advancing to step 3:
805 divided by 340 is 2 with a remainder of 125.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we subtract 680 from 805, we get 125.
Grab the next digit (3) from the dividend, add it to 125, then carry on: 1253 / 340

Moving on to step 4:
340 can be fit into 1253 3 times, resulting in a remainder of 233.
Use 3 as the next digit of our solution. 
Result so far: 23.0
Deduct 1020 from 1253 and we're left with 233.
Bring next digit (1) of the dividend behind the 233 and repeat the process: 2331 / 340

Step 5:
The number 340 fits into 2331 6 times, leaving a remainder of 291.
Record the quotient 6 as the next digit in the result. 
Result so far: 236.0
Subtracting 2040 from 2331 leaves us with 291.
Fetch the next digit (5) from the dividend, attach it to 291 and continue: 2915 / 340

Let's proceed to step 6:
340 goes into 2915 8 times with a remainder of 195.
The next digit of our result is 8. 
Result so far: 2368.0
Subtract 2720 from 2915 to get 195.
Fetch the next digit (6) from the dividend, attach it to 195 and continue: 1956 / 340

On to step 7:
340 can be fit into 1956 5 times, resulting in a remainder of 256.
Record the quotient 5 as the next digit in the result. 
Result so far: 23685.0
If we subtract 1700 from 1956, we get 256.
Bring next digit (4) of the dividend behind the 256 and repeat the process: 2564 / 340

Advancing to step 8:
340 goes into 2564 7 times with a remainder of 184.
Record the quotient 7 as the next digit in the result. 
Result so far: 236857.0
Subtract 2380 from 2564 to get 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Let's proceed to step 9:
340 can be fit into 1840 5 times, resulting in a remainder of 140.
Record the quotient 5 as the next digit in the result. 
Result so far: 236857.5
If we take 1700 away from 1840, we end up with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Advancing to step 10:
The number 340 fits into 1400 4 times, leaving a remainder of 40.
Record the quotient 4 as the next digit in the result. 
Result so far: 236857.54
If we subtract 1360 from 1400, 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 11:
340 can be fit into 400 1 times, resulting in a remainder of 60.
The number 1 becomes the next digit in our result. 
Result so far: 236857.541
Subtract 340 from 400 to get 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 12:
340 can be fit into 600 1 times, resulting in a remainder of 260.
Put 1 as the next digit of the answer. 
Result so far: 236857.5411
If we take 340 away from 600, we end up with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

In conclusion, the division gives 236857.5411 with a balance of 0.0026.
