40253857 ÷ 340 
We're looking to find how many times 340 goes into 40253857.

Step 1:
340 goes into 4 0 times with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Take the next digit (0) from the dividend and append it to 4, then repeat: 40 / 340

Let's proceed to step 2:
The number 340 fits into 40 0 times, leaving a remainder of 40.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 40, we get 40.
Include the next digit (2) from the dividend after 40, then repeat: 402 / 340

Advancing to step 3:
340 goes into 402 1 times with a remainder of 62.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 340 from 402 and we're left with 62.
Take the next digit (5) from the dividend and append it to 62, then repeat: 625 / 340

On to step 4:
340 can be fit into 625 1 times, resulting in a remainder of 285.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
If we subtract 340 from 625, we get 285.
Include the next digit (3) from the dividend after 285, then repeat: 2853 / 340

Going ahead to step 5:
The number 340 fits into 2853 8 times, leaving a remainder of 133.
The next digit of our result is 8. 
Result so far: 118.0
Subtract 2720 from 2853 to get 133.
Grab the next digit (8) from the dividend, add it to 133, then carry on: 1338 / 340

Moving on to step 6:
340 can be fit into 1338 3 times, resulting in a remainder of 318.
Record the quotient 3 as the next digit in the result. 
Result so far: 1183.0
If we subtract 1020 from 1338, we get 318.
Take the next digit (5) from the dividend and append it to 318, then repeat: 3185 / 340

Step 7:
3185 divided by 340 is 9 with a remainder of 125.
Write down 9 as next digit of the result. 
Result so far: 11839.0
Deduct 3060 from 3185 and we're left with 125.
Append the next digit (7) from the dividend to 125 and continue with: 1257 / 340

Going ahead to step 8:
The number 340 fits into 1257 3 times, leaving a remainder of 237.
Record the quotient 3 as the next digit in the result. 
Result so far: 118393.0
If we take 1020 away from 1257, we end up with 237.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2370, and continue the process.

Advancing to step 9:
340 can be fit into 2370 6 times, resulting in a remainder of 330.
Record the quotient 6 as the next digit in the result. 
Result so far: 118393.6
Subtracting 2040 from 2370 leaves us with 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Let's proceed to step 10:
When dividing 3300 by 340, we get 9 with a remainder of 240.
Put 9 as the next digit of the answer. 
Result so far: 118393.69
Deduct 3060 from 3300 and we're left with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Advancing to step 11:
340 can be fit into 2400 7 times, resulting in a remainder of 20.
Record the quotient 7 as the next digit in the result. 
Result so far: 118393.697
If we take 2380 away from 2400, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 12:
340 goes into 200 0 times with a remainder of 200.
Write down 0 as next digit of the result. 
Result so far: 118393.697
If we take 0 away from 200, we end up 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.

Step 13:
The number 340 fits into 2000 5 times, leaving a remainder of 300.
The next digit of our result is 5. 
Result so far: 118393.69705
Subtract 1700 from 2000 to get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Moving on to step 14:
The number 340 fits into 3000 8 times, leaving a remainder of 280.
Use 8 as the next digit of our solution. 
Result so far: 118393.697058
Subtract 2720 from 3000 to get 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Let's proceed to step 15:
If we divide 2800 by 340, we get 8 and a remainder of 80.
Write down 8 as next digit of the result. 
Result so far: 118393.6970588
Subtract 2720 from 2800 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.

The quotient of the division is 118393.6970588, and the remainder is 8e-07.
