39869552 ÷ 140 
Our goal is to divide 39869552 by 140.

Step 1:
If we divide 3 by 140, we get 0 and a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 140

Advancing to step 2:
The number 140 fits into 39 0 times, leaving a remainder of 39.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 39 leaves us with 39.
Grab the next digit (8) from the dividend, add it to 39, then carry on: 398 / 140

Advancing to step 3:
When dividing 398 by 140, we get 2 with a remainder of 118.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we subtract 280 from 398, we get 118.
Take the next digit (6) from the dividend and append it to 118, then repeat: 1186 / 140

Going ahead to step 4:
140 goes into 1186 8 times with a remainder of 66.
Write down 8 as next digit of the result. 
Result so far: 28.0
If we subtract 1120 from 1186, we get 66.
Take the next digit (9) from the dividend and append it to 66, then repeat: 669 / 140

Moving on to step 5:
669 divided by 140 is 4 with a remainder of 109.
Record the quotient 4 as the next digit in the result. 
Result so far: 284.0
If we subtract 560 from 669, we get 109.
Take the next digit (5) from the dividend and append it to 109, then repeat: 1095 / 140

Going ahead to step 6:
140 goes into 1095 7 times with a remainder of 115.
Put 7 as the next digit of the answer. 
Result so far: 2847.0
Subtracting 980 from 1095 leaves us with 115.
Append the next digit (5) from the dividend to 115 and continue with: 1155 / 140

Step 7:
If we divide 1155 by 140, we get 8 and a remainder of 35.
Write down 8 as next digit of the result. 
Result so far: 28478.0
If we subtract 1120 from 1155, we get 35.
Bring next digit (2) of the dividend behind the 35 and repeat the process: 352 / 140

Step 8:
When dividing 352 by 140, we get 2 with a remainder of 72.
Write down 2 as next digit of the result. 
Result so far: 284782.0
Subtracting 280 from 352 leaves us with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Moving on to step 9:
140 goes into 720 5 times with a remainder of 20.
Use 5 as the next digit of our solution. 
Result so far: 284782.5
Subtracting 700 from 720 leaves us 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.

Let's proceed to step 10:
The number 140 fits into 200 1 times, leaving a remainder of 60.
Record the quotient 1 as the next digit in the result. 
Result so far: 284782.51
Subtracting 140 from 200 leaves us 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.

Moving on to step 11:
600 divided by 140 is 4 with a remainder of 40.
Record the quotient 4 as the next digit in the result. 
Result so far: 284782.514
Subtract 560 from 600 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.

Going ahead to step 12:
400 divided by 140 is 2 with a remainder of 120.
Write down 2 as next digit of the result. 
Result so far: 284782.5142
Subtract 280 from 400 to 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.

On to step 13:
1200 divided by 140 is 8 with a remainder of 80.
Use 8 as the next digit of our solution. 
Result so far: 284782.51428
The remainder is 80 after subtracting 1120 from 1200.
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:
The number 140 fits into 800 5 times, leaving a remainder of 100.
Record the quotient 5 as the next digit in the result. 
Result so far: 284782.514285
If we take 700 away from 800, we end up with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Going ahead to step 15:
140 goes into 1000 7 times with a remainder of 20.
Use 7 as the next digit of our solution. 
Result so far: 284782.5142857
If we subtract 980 from 1000, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 16:
The number 140 fits into 200 1 times, leaving a remainder of 60.
Use 1 as the next digit of our solution. 
Result so far: 284782.51428571
If we subtract 140 from 200, we 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.

The final result is 284782.51428571 with a remainder of 6e-08.
