73811149 divided by 428 
Our goal is to divide 73811149 by 428.

On to step 1:
7 divided by 428 is 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Append the next digit (3) from the dividend to 7 and continue with: 73 / 428

Moving on to step 2:
When dividing 73 by 428, we get 0 with a remainder of 73.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 73, we end up with 73.
Include the next digit (8) from the dividend after 73, then repeat: 738 / 428

On to step 3:
When dividing 738 by 428, we get 1 with a remainder of 310.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 310 after subtracting 428 from 738.
Append the next digit (1) from the dividend to 310 and continue with: 3101 / 428

Going ahead to step 4:
If we divide 3101 by 428, we get 7 and a remainder of 105.
Record the quotient 7 as the next digit in the result. 
Result so far: 17.0
If we subtract 2996 from 3101, we get 105.
Take the next digit (1) from the dividend and append it to 105, then repeat: 1051 / 428

Step 5:
1051 divided by 428 is 2 with a remainder of 195.
The number 2 becomes the next digit in our result. 
Result so far: 172.0
If we take 856 away from 1051, we end up with 195.
Append the next digit (1) from the dividend to 195 and continue with: 1951 / 428

Moving on to step 6:
428 goes into 1951 4 times with a remainder of 239.
The next digit of our result is 4. 
Result so far: 1724.0
Subtracting 1712 from 1951 leaves us with 239.
Grab the next digit (4) from the dividend, add it to 239, then carry on: 2394 / 428

On to step 7:
428 can be fit into 2394 5 times, resulting in a remainder of 254.
Use 5 as the next digit of our solution. 
Result so far: 17245.0
If we subtract 2140 from 2394, we get 254.
Take the next digit (9) from the dividend and append it to 254, then repeat: 2549 / 428

Step 8:
428 can be fit into 2549 5 times, resulting in a remainder of 409.
Record the quotient 5 as the next digit in the result. 
Result so far: 172455.0
The remainder is 409 after subtracting 2140 from 2549.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4090, and continue the process.

Advancing to step 9:
If we divide 4090 by 428, we get 9 and a remainder of 238.
Put 9 as the next digit of the answer. 
Result so far: 172455.9
Deduct 3852 from 4090 and we're left with 238.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

Moving on to step 10:
If we divide 2380 by 428, we get 5 and a remainder of 240.
Write down 5 as next digit of the result. 
Result so far: 172455.95
If we subtract 2140 from 2380, we get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Moving on to step 11:
If we divide 2400 by 428, we get 5 and a remainder of 260.
Use 5 as the next digit of our solution. 
Result so far: 172455.955
Subtracting 2140 from 2400 leaves us with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

The final outcome is 172455.955, with a leftover of 0.026.
