43487857 ÷ 316 
We're looking to find how many times 316 goes into 43487857.

Step 1:
316 goes into 4 0 times with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Append the next digit (3) from the dividend to 4 and continue with: 43 / 316

On to step 2:
The number 316 fits into 43 0 times, leaving a remainder of 43.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 43 to get 43.
Append the next digit (4) from the dividend to 43 and continue with: 434 / 316

Going ahead to step 3:
If we divide 434 by 316, we get 1 and a remainder of 118.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 118 after subtracting 316 from 434.
Fetch the next digit (8) from the dividend, attach it to 118 and continue: 1188 / 316

On to step 4:
If we divide 1188 by 316, we get 3 and a remainder of 240.
Put 3 as the next digit of the answer. 
Result so far: 13.0
Deduct 948 from 1188 and we're left with 240.
Take the next digit (7) from the dividend and append it to 240, then repeat: 2407 / 316

Let's proceed to step 5:
316 goes into 2407 7 times with a remainder of 195.
Use 7 as the next digit of our solution. 
Result so far: 137.0
The remainder is 195 after subtracting 2212 from 2407.
Include the next digit (8) from the dividend after 195, then repeat: 1958 / 316

Moving on to step 6:
316 goes into 1958 6 times with a remainder of 62.
Use 6 as the next digit of our solution. 
Result so far: 1376.0
Deduct 1896 from 1958 and we're left with 62.
Fetch the next digit (5) from the dividend, attach it to 62 and continue: 625 / 316

Moving on to step 7:
If we divide 625 by 316, we get 1 and a remainder of 309.
Put 1 as the next digit of the answer. 
Result so far: 13761.0
Subtract 316 from 625 to get 309.
Grab the next digit (7) from the dividend, add it to 309, then carry on: 3097 / 316

Moving on to step 8:
When dividing 3097 by 316, we get 9 with a remainder of 253.
Write down 9 as next digit of the result. 
Result so far: 137619.0
If we subtract 2844 from 3097, we get 253.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2530, and continue the process.

Advancing to step 9:
316 goes into 2530 8 times with a remainder of 2.
The next digit of our result is 8. 
Result so far: 137619.8
If we take 2528 away from 2530, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 10:
The number 316 fits into 20 0 times, leaving a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 137619.8
If we take 0 away from 20, 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.

On to step 11:
When dividing 200 by 316, we get 0 with a remainder of 200.
The next digit of our result is 0. 
Result so far: 137619.8
The remainder is 200 after subtracting 0 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

The final outcome is 137619.8, with a leftover of 0.02.
