Let's divide 74879990 by 412
We want to divide 74879990 by 412.

Step 1:
When dividing 7 by 412, we get 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Bring next digit (4) of the dividend behind the 7 and repeat the process: 74 / 412

On to step 2:
412 can be fit into 74 0 times, resulting in a remainder of 74.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 74 and we're left with 74.
Append the next digit (8) from the dividend to 74 and continue with: 748 / 412

Let's proceed to step 3:
If we divide 748 by 412, we get 1 and a remainder of 336.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 336 after subtracting 412 from 748.
Include the next digit (7) from the dividend after 336, then repeat: 3367 / 412

Let's proceed to step 4:
3367 divided by 412 is 8 with a remainder of 71.
Write down 8 as next digit of the result. 
Result so far: 18.0
Deduct 3296 from 3367 and we're left with 71.
Include the next digit (9) from the dividend after 71, then repeat: 719 / 412

Advancing to step 5:
412 can be fit into 719 1 times, resulting in a remainder of 307.
Write down 1 as next digit of the result. 
Result so far: 181.0
Subtracting 412 from 719 leaves us with 307.
Bring next digit (9) of the dividend behind the 307 and repeat the process: 3079 / 412

Let's proceed to step 6:
412 goes into 3079 7 times with a remainder of 195.
Use 7 as the next digit of our solution. 
Result so far: 1817.0
Subtracting 2884 from 3079 leaves us with 195.
Include the next digit (9) from the dividend after 195, then repeat: 1959 / 412

Moving on to step 7:
The number 412 fits into 1959 4 times, leaving a remainder of 311.
Record the quotient 4 as the next digit in the result. 
Result so far: 18174.0
If we take 1648 away from 1959, we end up with 311.
Include the next digit (0) from the dividend after 311, then repeat: 3110 / 412

On to step 8:
3110 divided by 412 is 7 with a remainder of 226.
The next digit of our result is 7. 
Result so far: 181747.0
The remainder is 226 after subtracting 2884 from 3110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

Step 9:
412 can be fit into 2260 5 times, resulting in a remainder of 200.
Put 5 as the next digit of the answer. 
Result so far: 181747.5
If we take 2060 away from 2260, we end up with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Going ahead to step 10:
412 can be fit into 2000 4 times, resulting in a remainder of 352.
Put 4 as the next digit of the answer. 
Result so far: 181747.54
The remainder is 352 after subtracting 1648 from 2000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

On to step 11:
The number 412 fits into 3520 8 times, leaving a remainder of 224.
Put 8 as the next digit of the answer. 
Result so far: 181747.548
Subtract 3296 from 3520 to get 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Let's proceed to step 12:
When dividing 2240 by 412, we get 5 with a remainder of 180.
Record the quotient 5 as the next digit in the result. 
Result so far: 181747.5485
If we subtract 2060 from 2240, we get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

On to step 13:
When dividing 1800 by 412, we get 4 with a remainder of 152.
Use 4 as the next digit of our solution. 
Result so far: 181747.54854
Subtract 1648 from 1800 to get 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Going ahead to step 14:
1520 divided by 412 is 3 with a remainder of 284.
Use 3 as the next digit of our solution. 
Result so far: 181747.548543
Deduct 1236 from 1520 and we're left with 284.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

Let's proceed to step 15:
The number 412 fits into 2840 6 times, leaving a remainder of 368.
Use 6 as the next digit of our solution. 
Result so far: 181747.5485436
Subtract 2472 from 2840 to get 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

Moving on to step 16:
If we divide 3680 by 412, we get 8 and a remainder of 384.
Use 8 as the next digit of our solution. 
Result so far: 181747.54854368
Deduct 3296 from 3680 and we're left with 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

The final result is 181747.54854368 with a remainder of 3.84e-07.
