57158195 ÷ 438 
We're looking to find how many times 438 goes into 57158195.

Step 1:
5 divided by 438 is 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Append the next digit (7) from the dividend to 5 and continue with: 57 / 438

Moving on to step 2:
57 divided by 438 is 0 with a remainder of 57.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 57, we end up with 57.
Take the next digit (1) from the dividend and append it to 57, then repeat: 571 / 438

On to step 3:
The number 438 fits into 571 1 times, leaving a remainder of 133.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 438 from 571, we get 133.
Fetch the next digit (5) from the dividend, attach it to 133 and continue: 1335 / 438

On to step 4:
1335 divided by 438 is 3 with a remainder of 21.
Write down 3 as next digit of the result. 
Result so far: 13.0
If we subtract 1314 from 1335, we get 21.
Grab the next digit (8) from the dividend, add it to 21, then carry on: 218 / 438

Step 5:
438 can be fit into 218 0 times, resulting in a remainder of 218.
Write down 0 as next digit of the result. 
Result so far: 130.0
Deduct 0 from 218 and we're left with 218.
Fetch the next digit (1) from the dividend, attach it to 218 and continue: 2181 / 438

On to step 6:
2181 divided by 438 is 4 with a remainder of 429.
The number 4 becomes the next digit in our result. 
Result so far: 1304.0
The remainder is 429 after subtracting 1752 from 2181.
Append the next digit (9) from the dividend to 429 and continue with: 4299 / 438

Advancing to step 7:
438 goes into 4299 9 times with a remainder of 357.
The next digit of our result is 9. 
Result so far: 13049.0
If we subtract 3942 from 4299, we get 357.
Append the next digit (5) from the dividend to 357 and continue with: 3575 / 438

Step 8:
If we divide 3575 by 438, we get 8 and a remainder of 71.
Put 8 as the next digit of the answer. 
Result so far: 130498.0
If we subtract 3504 from 3575, we get 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Advancing to step 9:
710 divided by 438 is 1 with a remainder of 272.
The number 1 becomes the next digit in our result. 
Result so far: 130498.1
The remainder is 272 after subtracting 438 from 710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

Going ahead to step 10:
If we divide 2720 by 438, we get 6 and a remainder of 92.
Put 6 as the next digit of the answer. 
Result so far: 130498.16
If we subtract 2628 from 2720, we get 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Moving on to step 11:
920 divided by 438 is 2 with a remainder of 44.
The next digit of our result is 2. 
Result so far: 130498.162
If we take 876 away from 920, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 12:
440 divided by 438 is 1 with a remainder of 2.
Use 1 as the next digit of our solution. 
Result so far: 130498.1621
If we take 438 away from 440, 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.

Step 13:
If we divide 20 by 438, we get 0 and a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 130498.1621
Subtracting 0 from 20 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.

Step 14:
438 goes into 200 0 times with a remainder of 200.
Put 0 as the next digit of the answer. 
Result so far: 130498.1621
If we subtract 0 from 200, we get 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 result is 130498.1621 with a remainder of 2e-05.
