Let's divide 72106985 by 578
Our goal is to divide 72106985 by 578.

On to step 1:
The number 578 fits into 7 0 times, leaving 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 (2) from the dividend to 7 and continue with: 72 / 578

Moving on to step 2:
If we divide 72 by 578, we get 0 and a remainder of 72.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 72 leaves us with 72.
Take the next digit (1) from the dividend and append it to 72, then repeat: 721 / 578

Step 3:
578 goes into 721 1 times with a remainder of 143.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 578 away from 721, we end up with 143.
Append the next digit (0) from the dividend to 143 and continue with: 1430 / 578

Moving on to step 4:
578 goes into 1430 2 times with a remainder of 274.
Write down 2 as next digit of the result. 
Result so far: 12.0
If we subtract 1156 from 1430, we get 274.
Bring next digit (6) of the dividend behind the 274 and repeat the process: 2746 / 578

Advancing to step 5:
2746 divided by 578 is 4 with a remainder of 434.
Record the quotient 4 as the next digit in the result. 
Result so far: 124.0
If we take 2312 away from 2746, we end up with 434.
Bring next digit (9) of the dividend behind the 434 and repeat the process: 4349 / 578

On to step 6:
The number 578 fits into 4349 7 times, leaving a remainder of 303.
Write down 7 as next digit of the result. 
Result so far: 1247.0
Subtracting 4046 from 4349 leaves us with 303.
Fetch the next digit (8) from the dividend, attach it to 303 and continue: 3038 / 578

On to step 7:
The number 578 fits into 3038 5 times, leaving a remainder of 148.
Write down 5 as next digit of the result. 
Result so far: 12475.0
Subtracting 2890 from 3038 leaves us with 148.
Take the next digit (5) from the dividend and append it to 148, then repeat: 1485 / 578

Step 8:
578 goes into 1485 2 times with a remainder of 329.
Record the quotient 2 as the next digit in the result. 
Result so far: 124752.0
If we subtract 1156 from 1485, we get 329.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3290, and continue the process.

Going ahead to step 9:
If we divide 3290 by 578, we get 5 and a remainder of 400.
Use 5 as the next digit of our solution. 
Result so far: 124752.5
The remainder is 400 after subtracting 2890 from 3290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Advancing to step 10:
4000 divided by 578 is 6 with a remainder of 532.
The number 6 becomes the next digit in our result. 
Result so far: 124752.56
Deduct 3468 from 4000 and we're left with 532.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5320, and continue the process.

Step 11:
5320 divided by 578 is 9 with a remainder of 118.
Put 9 as the next digit of the answer. 
Result so far: 124752.569
Subtracting 5202 from 5320 leaves us with 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

Moving on to step 12:
The number 578 fits into 1180 2 times, leaving a remainder of 24.
The next digit of our result is 2. 
Result so far: 124752.5692
Subtract 1156 from 1180 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 13:
When dividing 240 by 578, we get 0 with a remainder of 240.
Put 0 as the next digit of the answer. 
Result so far: 124752.5692
Subtracting 0 from 240 leaves us with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

On to step 14:
578 can be fit into 2400 4 times, resulting in a remainder of 88.
The number 4 becomes the next digit in our result. 
Result so far: 124752.569204
If we take 2312 away from 2400, we end up with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Moving on to step 15:
578 can be fit into 880 1 times, resulting in a remainder of 302.
Record the quotient 1 as the next digit in the result. 
Result so far: 124752.5692041
The remainder is 302 after subtracting 578 from 880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3020, and continue the process.

Step 16:
578 goes into 3020 5 times with a remainder of 130.
Write down 5 as next digit of the result. 
Result so far: 124752.56920415
The remainder is 130 after subtracting 2890 from 3020.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

After the division, we end up with 124752.56920415 and a remainder of 1.3e-07.
