31917346 ÷ 140 
We want to figure out the number of times 31917346 can be divided by 140.

Advancing to step 1:
When dividing 3 by 140, we get 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Take the next digit (1) from the dividend and append it to 3, then repeat: 31 / 140

Let's proceed to step 2:
140 can be fit into 31 0 times, resulting in a remainder of 31.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 31 and we're left with 31.
Append the next digit (9) from the dividend to 31 and continue with: 319 / 140

Moving on to step 3:
If we divide 319 by 140, we get 2 and a remainder of 39.
Put 2 as the next digit of the answer. 
Result so far: 2.0
The remainder is 39 after subtracting 280 from 319.
Bring next digit (1) of the dividend behind the 39 and repeat the process: 391 / 140

Step 4:
140 can be fit into 391 2 times, resulting in a remainder of 111.
The number 2 becomes the next digit in our result. 
Result so far: 22.0
Subtract 280 from 391 to get 111.
Bring next digit (7) of the dividend behind the 111 and repeat the process: 1117 / 140

Moving on to step 5:
If we divide 1117 by 140, we get 7 and a remainder of 137.
The number 7 becomes the next digit in our result. 
Result so far: 227.0
The remainder is 137 after subtracting 980 from 1117.
Bring next digit (3) of the dividend behind the 137 and repeat the process: 1373 / 140

Let's proceed to step 6:
1373 divided by 140 is 9 with a remainder of 113.
Put 9 as the next digit of the answer. 
Result so far: 2279.0
If we take 1260 away from 1373, we end up with 113.
Bring next digit (4) of the dividend behind the 113 and repeat the process: 1134 / 140

Advancing to step 7:
1134 divided by 140 is 8 with a remainder of 14.
The number 8 becomes the next digit in our result. 
Result so far: 22798.0
Subtract 1120 from 1134 to get 14.
Bring next digit (6) of the dividend behind the 14 and repeat the process: 146 / 140

Advancing to step 8:
The number 140 fits into 146 1 times, leaving a remainder of 6.
The number 1 becomes the next digit in our result. 
Result so far: 227981.0
The remainder is 6 after subtracting 140 from 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 9:
If we divide 60 by 140, we get 0 and a remainder of 60.
The next digit of our result is 0. 
Result so far: 227981.0
If we subtract 0 from 60, 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.

Moving on to step 10:
When dividing 600 by 140, we get 4 with a remainder of 40.
Put 4 as the next digit of the answer. 
Result so far: 227981.04
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 11:
When dividing 400 by 140, we get 2 with a remainder of 120.
Write down 2 as next digit of the result. 
Result so far: 227981.042
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.

Step 12:
1200 divided by 140 is 8 with a remainder of 80.
The number 8 becomes the next digit in our result. 
Result so far: 227981.0428
Subtracting 1120 from 1200 leaves us 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.

Step 13:
140 can be fit into 800 5 times, resulting in a remainder of 100.
The number 5 becomes the next digit in our result. 
Result so far: 227981.04285
If we subtract 700 from 800, 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.

Advancing to step 14:
140 goes into 1000 7 times with a remainder of 20.
Put 7 as the next digit of the answer. 
Result so far: 227981.042857
The remainder is 20 after subtracting 980 from 1000.
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 15:
200 divided by 140 is 1 with a remainder of 60.
Record the quotient 1 as the next digit in the result. 
Result so far: 227981.0428571
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.

Let's proceed to step 16:
140 goes into 600 4 times with a remainder of 40.
The number 4 becomes the next digit in our result. 
Result so far: 227981.04285714
If we subtract 560 from 600, 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.

The final outcome is 227981.04285714, with a leftover of 4e-08.
