58378765 ÷ 438 
We want to divide 58378765 by 438.

Advancing to step 1:
5 divided by 438 is 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.
Take the next digit (8) from the dividend and append it to 5, then repeat: 58 / 438

Step 2:
If we divide 58 by 438, we get 0 and a remainder of 58.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 58 leaves us with 58.
Take the next digit (3) from the dividend and append it to 58, then repeat: 583 / 438

On to step 3:
583 divided by 438 is 1 with a remainder of 145.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 438 from 583 leaves us with 145.
Append the next digit (7) from the dividend to 145 and continue with: 1457 / 438

Going ahead to step 4:
438 goes into 1457 3 times with a remainder of 143.
The next digit of our result is 3. 
Result so far: 13.0
If we subtract 1314 from 1457, we get 143.
Grab the next digit (8) from the dividend, add it to 143, then carry on: 1438 / 438

Advancing to step 5:
1438 divided by 438 is 3 with a remainder of 124.
Write down 3 as next digit of the result. 
Result so far: 133.0
If we take 1314 away from 1438, we end up with 124.
Append the next digit (7) from the dividend to 124 and continue with: 1247 / 438

Advancing to step 6:
When dividing 1247 by 438, we get 2 with a remainder of 371.
The next digit of our result is 2. 
Result so far: 1332.0
If we take 876 away from 1247, we end up with 371.
Take the next digit (6) from the dividend and append it to 371, then repeat: 3716 / 438

Step 7:
When dividing 3716 by 438, we get 8 with a remainder of 212.
The number 8 becomes the next digit in our result. 
Result so far: 13328.0
Subtract 3504 from 3716 to get 212.
Append the next digit (5) from the dividend to 212 and continue with: 2125 / 438

Going ahead to step 8:
If we divide 2125 by 438, we get 4 and a remainder of 373.
The next digit of our result is 4. 
Result so far: 133284.0
If we subtract 1752 from 2125, we get 373.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3730, and continue the process.

Going ahead to step 9:
438 can be fit into 3730 8 times, resulting in a remainder of 226.
Put 8 as the next digit of the answer. 
Result so far: 133284.8
If we take 3504 away from 3730, we end up with 226.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

Let's proceed to step 10:
The number 438 fits into 2260 5 times, leaving a remainder of 70.
Record the quotient 5 as the next digit in the result. 
Result so far: 133284.85
If we subtract 2190 from 2260, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Let's proceed to step 11:
If we divide 700 by 438, we get 1 and a remainder of 262.
Write down 1 as next digit of the result. 
Result so far: 133284.851
The remainder is 262 after subtracting 438 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2620, and continue the process.

Moving on to step 12:
2620 divided by 438 is 5 with a remainder of 430.
Use 5 as the next digit of our solution. 
Result so far: 133284.8515
If we take 2190 away from 2620, we end up with 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

Step 13:
4300 divided by 438 is 9 with a remainder of 358.
Record the quotient 9 as the next digit in the result. 
Result so far: 133284.85159
Deduct 3942 from 4300 and we're left with 358.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3580, and continue the process.

Step 14:
3580 divided by 438 is 8 with a remainder of 76.
Put 8 as the next digit of the answer. 
Result so far: 133284.851598
Subtract 3504 from 3580 to get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Advancing to step 15:
438 can be fit into 760 1 times, resulting in a remainder of 322.
Write down 1 as next digit of the result. 
Result so far: 133284.8515981
If we subtract 438 from 760, we get 322.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3220, and continue the process.

Step 16:
The number 438 fits into 3220 7 times, leaving a remainder of 154.
The next digit of our result is 7. 
Result so far: 133284.85159817
Subtracting 3066 from 3220 leaves us with 154.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

The final outcome is 133284.85159817, with a leftover of 1.54e-07.
