78107123 ÷ 437 
We're looking to find how many times 437 goes into 78107123.

Moving on to step 1:
If we divide 7 by 437, we get 0 and a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 437

Step 2:
437 can be fit into 78 0 times, resulting in a remainder of 78.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 78 and we're left with 78.
Grab the next digit (1) from the dividend, add it to 78, then carry on: 781 / 437

Advancing to step 3:
781 divided by 437 is 1 with a remainder of 344.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 437 from 781 leaves us with 344.
Bring next digit (0) of the dividend behind the 344 and repeat the process: 3440 / 437

Let's proceed to step 4:
437 can be fit into 3440 7 times, resulting in a remainder of 381.
Write down 7 as next digit of the result. 
Result so far: 17.0
If we take 3059 away from 3440, we end up with 381.
Append the next digit (7) from the dividend to 381 and continue with: 3817 / 437

Going ahead to step 5:
When dividing 3817 by 437, we get 8 with a remainder of 321.
The number 8 becomes the next digit in our result. 
Result so far: 178.0
Deduct 3496 from 3817 and we're left with 321.
Include the next digit (1) from the dividend after 321, then repeat: 3211 / 437

Advancing to step 6:
If we divide 3211 by 437, we get 7 and a remainder of 152.
Write down 7 as next digit of the result. 
Result so far: 1787.0
If we subtract 3059 from 3211, we get 152.
Include the next digit (2) from the dividend after 152, then repeat: 1522 / 437

Let's proceed to step 7:
The number 437 fits into 1522 3 times, leaving a remainder of 211.
Write down 3 as next digit of the result. 
Result so far: 17873.0
Deduct 1311 from 1522 and we're left with 211.
Include the next digit (3) from the dividend after 211, then repeat: 2113 / 437

Advancing to step 8:
The number 437 fits into 2113 4 times, leaving a remainder of 365.
The next digit of our result is 4. 
Result so far: 178734.0
The remainder is 365 after subtracting 1748 from 2113.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3650, and continue the process.

Step 9:
The number 437 fits into 3650 8 times, leaving a remainder of 154.
The number 8 becomes the next digit in our result. 
Result so far: 178734.8
If we take 3496 away from 3650, we end up 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.

On to step 10:
When dividing 1540 by 437, we get 3 with a remainder of 229.
The next digit of our result is 3. 
Result so far: 178734.83
If we take 1311 away from 1540, we end up with 229.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2290, and continue the process.

Let's proceed to step 11:
The number 437 fits into 2290 5 times, leaving a remainder of 105.
The next digit of our result is 5. 
Result so far: 178734.835
Deduct 2185 from 2290 and we're left with 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Step 12:
437 can be fit into 1050 2 times, resulting in a remainder of 176.
The next digit of our result is 2. 
Result so far: 178734.8352
If we take 874 away from 1050, we end up with 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Moving on to step 13:
437 can be fit into 1760 4 times, resulting in a remainder of 12.
The number 4 becomes the next digit in our result. 
Result so far: 178734.83524
The remainder is 12 after subtracting 1748 from 1760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 14:
If we divide 120 by 437, we get 0 and a remainder of 120.
Put 0 as the next digit of the answer. 
Result so far: 178734.83524
If we take 0 away from 120, we end up 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.

Moving on to step 15:
When dividing 1200 by 437, we get 2 with a remainder of 326.
Put 2 as the next digit of the answer. 
Result so far: 178734.8352402
Deduct 874 from 1200 and we're left with 326.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3260, and continue the process.

Going ahead to step 16:
If we divide 3260 by 437, we get 7 and a remainder of 201.
Use 7 as the next digit of our solution. 
Result so far: 178734.83524027
If we take 3059 away from 3260, we end up with 201.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2010, and continue the process.

In conclusion, the division gives 178734.83524027 with a balance of 2.01e-07.
