We're dividing 15257210 by 148 
We want to figure out the number of times 15257210 can be divided by 148.

Moving on to step 1:
If we divide 1 by 148, we get 0 and a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 148

Step 2:
148 can be fit into 15 0 times, resulting in a remainder of 15.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 15 and we're left with 15.
Include the next digit (2) from the dividend after 15, then repeat: 152 / 148

Going ahead to step 3:
148 can be fit into 152 1 times, resulting in a remainder of 4.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 148 away from 152, we end up with 4.
Include the next digit (5) from the dividend after 4, then repeat: 45 / 148

Let's proceed to step 4:
The number 148 fits into 45 0 times, leaving a remainder of 45.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Subtracting 0 from 45 leaves us with 45.
Fetch the next digit (7) from the dividend, attach it to 45 and continue: 457 / 148

On to step 5:
When dividing 457 by 148, we get 3 with a remainder of 13.
The number 3 becomes the next digit in our result. 
Result so far: 103.0
If we subtract 444 from 457, we get 13.
Fetch the next digit (2) from the dividend, attach it to 13 and continue: 132 / 148

Let's proceed to step 6:
The number 148 fits into 132 0 times, leaving a remainder of 132.
Write down 0 as next digit of the result. 
Result so far: 1030.0
Subtract 0 from 132 to get 132.
Include the next digit (1) from the dividend after 132, then repeat: 1321 / 148

Moving on to step 7:
If we divide 1321 by 148, we get 8 and a remainder of 137.
Put 8 as the next digit of the answer. 
Result so far: 10308.0
Deduct 1184 from 1321 and we're left with 137.
Bring next digit (0) of the dividend behind the 137 and repeat the process: 1370 / 148

Step 8:
If we divide 1370 by 148, we get 9 and a remainder of 38.
Write down 9 as next digit of the result. 
Result so far: 103089.0
Subtract 1332 from 1370 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 9:
The number 148 fits into 380 2 times, leaving a remainder of 84.
Write down 2 as next digit of the result. 
Result so far: 103089.2
If we take 296 away from 380, we end up with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Advancing to step 10:
148 can be fit into 840 5 times, resulting in a remainder of 100.
The number 5 becomes the next digit in our result. 
Result so far: 103089.25
Subtracting 740 from 840 leaves us with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

On to step 11:
If we divide 1000 by 148, we get 6 and a remainder of 112.
The number 6 becomes the next digit in our result. 
Result so far: 103089.256
If we subtract 888 from 1000, we get 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Moving on to step 12:
If we divide 1120 by 148, we get 7 and a remainder of 84.
Put 7 as the next digit of the answer. 
Result so far: 103089.2567
Deduct 1036 from 1120 and we're left with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Step 13:
148 can be fit into 840 5 times, resulting in a remainder of 100.
The next digit of our result is 5. 
Result so far: 103089.25675
Deduct 740 from 840 and we're left with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Step 14:
1000 divided by 148 is 6 with a remainder of 112.
Record the quotient 6 as the next digit in the result. 
Result so far: 103089.256756
The remainder is 112 after subtracting 888 from 1000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Moving on to step 15:
148 can be fit into 1120 7 times, resulting in a remainder of 84.
The next digit of our result is 7. 
Result so far: 103089.2567567
Subtract 1036 from 1120 to get 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Moving on to step 16:
The number 148 fits into 840 5 times, leaving a remainder of 100.
Record the quotient 5 as the next digit in the result. 
Result so far: 103089.25675675
The remainder is 100 after subtracting 740 from 840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

The final outcome is 103089.25675675, with a leftover of 1e-07.
