We divide 57087988 by 140
We want to figure out the number of times 57087988 can be divided by 140.

Advancing to step 1:
When dividing 5 by 140, we get 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Grab the next digit (7) from the dividend, add it to 5, then carry on: 57 / 140

Advancing to step 2:
When dividing 57 by 140, we get 0 with a remainder of 57.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 57 to get 57.
Append the next digit (0) from the dividend to 57 and continue with: 570 / 140

Going ahead to step 3:
140 can be fit into 570 4 times, resulting in a remainder of 10.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we subtract 560 from 570, we get 10.
Grab the next digit (8) from the dividend, add it to 10, then carry on: 108 / 140

Going ahead to step 4:
If we divide 108 by 140, we get 0 and a remainder of 108.
Write down 0 as next digit of the result. 
Result so far: 40.0
The remainder is 108 after subtracting 0 from 108.
Append the next digit (7) from the dividend to 108 and continue with: 1087 / 140

Advancing to step 5:
140 goes into 1087 7 times with a remainder of 107.
The number 7 becomes the next digit in our result. 
Result so far: 407.0
If we take 980 away from 1087, we end up with 107.
Take the next digit (9) from the dividend and append it to 107, then repeat: 1079 / 140

Step 6:
140 can be fit into 1079 7 times, resulting in a remainder of 99.
The number 7 becomes the next digit in our result. 
Result so far: 4077.0
Subtract 980 from 1079 to get 99.
Take the next digit (8) from the dividend and append it to 99, then repeat: 998 / 140

Moving on to step 7:
140 goes into 998 7 times with a remainder of 18.
Record the quotient 7 as the next digit in the result. 
Result so far: 40777.0
The remainder is 18 after subtracting 980 from 998.
Include the next digit (8) from the dividend after 18, then repeat: 188 / 140

Moving on to step 8:
If we divide 188 by 140, we get 1 and a remainder of 48.
Record the quotient 1 as the next digit in the result. 
Result so far: 407771.0
Deduct 140 from 188 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 9:
The number 140 fits into 480 3 times, leaving a remainder of 60.
Put 3 as the next digit of the answer. 
Result so far: 407771.3
Deduct 420 from 480 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 10:
140 can be fit into 600 4 times, resulting in a remainder of 40.
The number 4 becomes the next digit in our result. 
Result so far: 407771.34
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.

Step 11:
If we divide 400 by 140, we get 2 and a remainder of 120.
The number 2 becomes the next digit in our result. 
Result so far: 407771.342
Subtracting 280 from 400 leaves us with 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:
If we divide 1200 by 140, we get 8 and a remainder of 80.
Put 8 as the next digit of the answer. 
Result so far: 407771.3428
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 13:
140 goes into 800 5 times with a remainder of 100.
The next digit of our result is 5. 
Result so far: 407771.34285
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.

Advancing to step 14:
When dividing 1000 by 140, we get 7 with a remainder of 20.
Write down 7 as next digit of the result. 
Result so far: 407771.342857
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.

Advancing to step 15:
The number 140 fits into 200 1 times, leaving a remainder of 60.
The next digit of our result is 1. 
Result so far: 407771.3428571
Subtract 140 from 200 to 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.

Advancing to step 16:
140 goes into 600 4 times with a remainder of 40.
Record the quotient 4 as the next digit in the result. 
Result so far: 407771.34285714
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 result is 407771.34285714 with a remainder of 4e-08.
