Let's divide 51571653 by 148
We want to figure out the number of times 51571653 can be divided by 148.

On to step 1:
148 goes into 5 0 times with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Append the next digit (1) from the dividend to 5 and continue with: 51 / 148

Going ahead to step 2:
148 can be fit into 51 0 times, resulting in a remainder of 51.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 51 to get 51.
Grab the next digit (5) from the dividend, add it to 51, then carry on: 515 / 148

Moving on to step 3:
515 divided by 148 is 3 with a remainder of 71.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtract 444 from 515 to get 71.
Fetch the next digit (7) from the dividend, attach it to 71 and continue: 717 / 148

Step 4:
The number 148 fits into 717 4 times, leaving a remainder of 125.
Put 4 as the next digit of the answer. 
Result so far: 34.0
Subtracting 592 from 717 leaves us with 125.
Include the next digit (1) from the dividend after 125, then repeat: 1251 / 148

On to step 5:
148 goes into 1251 8 times with a remainder of 67.
Use 8 as the next digit of our solution. 
Result so far: 348.0
If we subtract 1184 from 1251, we get 67.
Bring next digit (6) of the dividend behind the 67 and repeat the process: 676 / 148

Let's proceed to step 6:
148 can be fit into 676 4 times, resulting in a remainder of 84.
The number 4 becomes the next digit in our result. 
Result so far: 3484.0
If we take 592 away from 676, we end up with 84.
Append the next digit (5) from the dividend to 84 and continue with: 845 / 148

On to step 7:
When dividing 845 by 148, we get 5 with a remainder of 105.
The number 5 becomes the next digit in our result. 
Result so far: 34845.0
Deduct 740 from 845 and we're left with 105.
Bring next digit (3) of the dividend behind the 105 and repeat the process: 1053 / 148

Advancing to step 8:
The number 148 fits into 1053 7 times, leaving a remainder of 17.
The number 7 becomes the next digit in our result. 
Result so far: 348457.0
The remainder is 17 after subtracting 1036 from 1053.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Going ahead to step 9:
If we divide 170 by 148, we get 1 and a remainder of 22.
The number 1 becomes the next digit in our result. 
Result so far: 348457.1
Subtracting 148 from 170 leaves us with 22.
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 10:
The number 148 fits into 220 1 times, leaving a remainder of 72.
Record the quotient 1 as the next digit in the result. 
Result so far: 348457.11
Subtract 148 from 220 to get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Our division results in 348457.11 with a remaining 0.072.
