Let's divide 18069920 by 140
We want to divide 18069920 by 140.

Advancing to step 1:
140 goes into 1 0 times with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 140

Going ahead to step 2:
140 goes into 18 0 times with a remainder of 18.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 18 to get 18.
Append the next digit (0) from the dividend to 18 and continue with: 180 / 140

Going ahead to step 3:
180 divided by 140 is 1 with a remainder of 40.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 140 from 180, we get 40.
Append the next digit (6) from the dividend to 40 and continue with: 406 / 140

Step 4:
140 can be fit into 406 2 times, resulting in a remainder of 126.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
Subtract 280 from 406 to get 126.
Include the next digit (9) from the dividend after 126, then repeat: 1269 / 140

Advancing to step 5:
When dividing 1269 by 140, we get 9 with a remainder of 9.
Use 9 as the next digit of our solution. 
Result so far: 129.0
Subtract 1260 from 1269 to get 9.
Bring next digit (9) of the dividend behind the 9 and repeat the process: 99 / 140

Moving on to step 6:
140 goes into 99 0 times with a remainder of 99.
Use 0 as the next digit of our solution. 
Result so far: 1290.0
If we subtract 0 from 99, we get 99.
Fetch the next digit (2) from the dividend, attach it to 99 and continue: 992 / 140

Step 7:
140 can be fit into 992 7 times, resulting in a remainder of 12.
Write down 7 as next digit of the result. 
Result so far: 12907.0
Deduct 980 from 992 and we're left with 12.
Bring next digit (0) of the dividend behind the 12 and repeat the process: 120 / 140

Going ahead to step 8:
140 can be fit into 120 0 times, resulting in a remainder of 120.
Write down 0 as next digit of the result. 
Result so far: 129070.0
Subtract 0 from 120 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.

Let's proceed to step 9:
140 goes into 1200 8 times with a remainder of 80.
Use 8 as the next digit of our solution. 
Result so far: 129070.8
Deduct 1120 from 1200 and we're left with 80.
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 10:
If we divide 800 by 140, we get 5 and a remainder of 100.
The number 5 becomes the next digit in our result. 
Result so far: 129070.85
Deduct 700 from 800 and we're left 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.

Moving on to step 11:
140 can be fit into 1000 7 times, resulting in a remainder of 20.
Put 7 as the next digit of the answer. 
Result so far: 129070.857
Subtract 980 from 1000 to 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.

On to step 12:
140 goes into 200 1 times with a remainder of 60.
Record the quotient 1 as the next digit in the result. 
Result so far: 129070.8571
Deduct 140 from 200 and we're left 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 13:
600 divided by 140 is 4 with a remainder of 40.
Use 4 as the next digit of our solution. 
Result so far: 129070.85714
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 14:
140 can be fit into 400 2 times, resulting in a remainder of 120.
Use 2 as the next digit of our solution. 
Result so far: 129070.857142
If we subtract 280 from 400, 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.

Moving on to step 15:
When dividing 1200 by 140, we get 8 with a remainder of 80.
Record the quotient 8 as the next digit in the result. 
Result so far: 129070.8571428
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.

Step 16:
140 can be fit into 800 5 times, resulting in a remainder of 100.
The next digit of our result is 5. 
Result so far: 129070.85714285
Subtract 700 from 800 to 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 result is 129070.85714285 with a remainder of 1e-07.
