We divide 12438737 by 148
We want to divide 12438737 by 148.

On to step 1:
The number 148 fits into 1 0 times, leaving a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 148

Advancing to step 2:
148 goes into 12 0 times with a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 12 to get 12.
Bring next digit (4) of the dividend behind the 12 and repeat the process: 124 / 148

Step 3:
124 divided by 148 is 0 with a remainder of 124.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 124 and we're left with 124.
Grab the next digit (3) from the dividend, add it to 124, then carry on: 1243 / 148

On to step 4:
The number 148 fits into 1243 8 times, leaving a remainder of 59.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Subtract 1184 from 1243 to get 59.
Grab the next digit (8) from the dividend, add it to 59, then carry on: 598 / 148

Going ahead to step 5:
598 divided by 148 is 4 with a remainder of 6.
Write down 4 as next digit of the result. 
Result so far: 84.0
Subtracting 592 from 598 leaves us with 6.
Grab the next digit (7) from the dividend, add it to 6, then carry on: 67 / 148

Let's proceed to step 6:
The number 148 fits into 67 0 times, leaving a remainder of 67.
The next digit of our result is 0. 
Result so far: 840.0
Subtracting 0 from 67 leaves us with 67.
Append the next digit (3) from the dividend to 67 and continue with: 673 / 148

Let's proceed to step 7:
673 divided by 148 is 4 with a remainder of 81.
The next digit of our result is 4. 
Result so far: 8404.0
Subtract 592 from 673 to get 81.
Append the next digit (7) from the dividend to 81 and continue with: 817 / 148

On to step 8:
The number 148 fits into 817 5 times, leaving a remainder of 77.
Record the quotient 5 as the next digit in the result. 
Result so far: 84045.0
Deduct 740 from 817 and we're left with 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Moving on to step 9:
148 can be fit into 770 5 times, resulting in a remainder of 30.
Write down 5 as next digit of the result. 
Result so far: 84045.5
Subtracting 740 from 770 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 10:
148 can be fit into 300 2 times, resulting in a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 84045.52
Deduct 296 from 300 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 11:
148 goes into 40 0 times with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 84045.52
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 12:
If we divide 400 by 148, we get 2 and a remainder of 104.
The next digit of our result is 2. 
Result so far: 84045.5202
The remainder is 104 after subtracting 296 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Let's proceed to step 13:
148 goes into 1040 7 times with a remainder of 4.
Write down 7 as next digit of the result. 
Result so far: 84045.52027
Subtract 1036 from 1040 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 14:
148 can be fit into 40 0 times, resulting in a remainder of 40.
The next digit of our result is 0. 
Result so far: 84045.52027
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 15:
148 goes into 400 2 times with a remainder of 104.
Put 2 as the next digit of the answer. 
Result so far: 84045.5202702
Subtracting 296 from 400 leaves us with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Going ahead to step 16:
The number 148 fits into 1040 7 times, leaving a remainder of 4.
The next digit of our result is 7. 
Result so far: 84045.52027027
The remainder is 4 after subtracting 1036 from 1040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

In conclusion, the division gives 84045.52027027 with a balance of 4e-09.
