45456981 divided by 340 
Our goal is to divide 45456981 by 340.

Moving on to step 1:
If we divide 4 by 340, we get 0 and a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Take the next digit (5) from the dividend and append it to 4, then repeat: 45 / 340

Step 2:
340 can be fit into 45 0 times, resulting in a remainder of 45.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 45 leaves us with 45.
Grab the next digit (4) from the dividend, add it to 45, then carry on: 454 / 340

Let's proceed to step 3:
340 can be fit into 454 1 times, resulting in a remainder of 114.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 114 after subtracting 340 from 454.
Append the next digit (5) from the dividend to 114 and continue with: 1145 / 340

On to step 4:
The number 340 fits into 1145 3 times, leaving a remainder of 125.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
The remainder is 125 after subtracting 1020 from 1145.
Fetch the next digit (6) from the dividend, attach it to 125 and continue: 1256 / 340

Advancing to step 5:
If we divide 1256 by 340, we get 3 and a remainder of 236.
The next digit of our result is 3. 
Result so far: 133.0
Subtracting 1020 from 1256 leaves us with 236.
Take the next digit (9) from the dividend and append it to 236, then repeat: 2369 / 340

Going ahead to step 6:
2369 divided by 340 is 6 with a remainder of 329.
Write down 6 as next digit of the result. 
Result so far: 1336.0
If we take 2040 away from 2369, we end up with 329.
Append the next digit (8) from the dividend to 329 and continue with: 3298 / 340

Advancing to step 7:
340 goes into 3298 9 times with a remainder of 238.
The next digit of our result is 9. 
Result so far: 13369.0
If we take 3060 away from 3298, we end up with 238.
Append the next digit (1) from the dividend to 238 and continue with: 2381 / 340

Advancing to step 8:
340 goes into 2381 7 times with a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 133697.0
Subtracting 2380 from 2381 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 9:
340 goes into 10 0 times with a remainder of 10.
The next digit of our result is 0. 
Result so far: 133697.0
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 10:
The number 340 fits into 100 0 times, leaving a remainder of 100.
Write down 0 as next digit of the result. 
Result so far: 133697.0
If we subtract 0 from 100, we get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

The final outcome is 133697.0, with a leftover of 0.1.
