79309417 divided by 438 
We want to divide 79309417 by 438.

Moving on to step 1:
When dividing 7 by 438, we get 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Bring next digit (9) of the dividend behind the 7 and repeat the process: 79 / 438

On to step 2:
If we divide 79 by 438, we get 0 and a remainder of 79.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 79 after subtracting 0 from 79.
Bring next digit (3) of the dividend behind the 79 and repeat the process: 793 / 438

Going ahead to step 3:
The number 438 fits into 793 1 times, leaving a remainder of 355.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 438 from 793 to get 355.
Append the next digit (0) from the dividend to 355 and continue with: 3550 / 438

On to step 4:
If we divide 3550 by 438, we get 8 and a remainder of 46.
Write down 8 as next digit of the result. 
Result so far: 18.0
Subtract 3504 from 3550 to get 46.
Bring next digit (9) of the dividend behind the 46 and repeat the process: 469 / 438

Step 5:
438 goes into 469 1 times with a remainder of 31.
Use 1 as the next digit of our solution. 
Result so far: 181.0
The remainder is 31 after subtracting 438 from 469.
Include the next digit (4) from the dividend after 31, then repeat: 314 / 438

Advancing to step 6:
If we divide 314 by 438, we get 0 and a remainder of 314.
The number 0 becomes the next digit in our result. 
Result so far: 1810.0
The remainder is 314 after subtracting 0 from 314.
Include the next digit (1) from the dividend after 314, then repeat: 3141 / 438

Let's proceed to step 7:
3141 divided by 438 is 7 with a remainder of 75.
Put 7 as the next digit of the answer. 
Result so far: 18107.0
Deduct 3066 from 3141 and we're left with 75.
Append the next digit (7) from the dividend to 75 and continue with: 757 / 438

Advancing to step 8:
If we divide 757 by 438, we get 1 and a remainder of 319.
Put 1 as the next digit of the answer. 
Result so far: 181071.0
If we take 438 away from 757, we end up with 319.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3190, and continue the process.

Step 9:
When dividing 3190 by 438, we get 7 with a remainder of 124.
Use 7 as the next digit of our solution. 
Result so far: 181071.7
If we take 3066 away from 3190, we end up with 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

Going ahead to step 10:
When dividing 1240 by 438, we get 2 with a remainder of 364.
Use 2 as the next digit of our solution. 
Result so far: 181071.72
Subtracting 876 from 1240 leaves us with 364.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

On to step 11:
438 goes into 3640 8 times with a remainder of 136.
Put 8 as the next digit of the answer. 
Result so far: 181071.728
If we take 3504 away from 3640, we end up with 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

On to step 12:
438 goes into 1360 3 times with a remainder of 46.
Record the quotient 3 as the next digit in the result. 
Result so far: 181071.7283
Subtracting 1314 from 1360 leaves us with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Going ahead to step 13:
If we divide 460 by 438, we get 1 and a remainder of 22.
Record the quotient 1 as the next digit in the result. 
Result so far: 181071.72831
The remainder is 22 after subtracting 438 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 14:
438 can be fit into 220 0 times, resulting in a remainder of 220.
Use 0 as the next digit of our solution. 
Result so far: 181071.72831
If we take 0 away from 220, we end up with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Advancing to step 15:
When dividing 2200 by 438, we get 5 with a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 181071.7283105
If we subtract 2190 from 2200, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 16:
438 can be fit into 100 0 times, resulting in a remainder of 100.
The next digit of our result is 0. 
Result so far: 181071.7283105
Subtracting 0 from 100 leaves us 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.

The final outcome is 181071.7283105, with a leftover of 1e-07.
