We're dividing 8151445 by 138 
Let's see how many times 138 fits into 8151445.

Let's proceed to step 1:
If we divide 8 by 138, we get 0 and a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 138

Let's proceed to step 2:
If we divide 81 by 138, we get 0 and a remainder of 81.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 81, we end up with 81.
Fetch the next digit (5) from the dividend, attach it to 81 and continue: 815 / 138

On to step 3:
138 can be fit into 815 5 times, resulting in a remainder of 125.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
If we subtract 690 from 815, we get 125.
Bring next digit (1) of the dividend behind the 125 and repeat the process: 1251 / 138

On to step 4:
If we divide 1251 by 138, we get 9 and a remainder of 9.
The number 9 becomes the next digit in our result. 
Result so far: 59.0
Subtracting 1242 from 1251 leaves us with 9.
Append the next digit (4) from the dividend to 9 and continue with: 94 / 138

Moving on to step 5:
When dividing 94 by 138, we get 0 with a remainder of 94.
Record the quotient 0 as the next digit in the result. 
Result so far: 590.0
Subtract 0 from 94 to get 94.
Take the next digit (4) from the dividend and append it to 94, then repeat: 944 / 138

Moving on to step 6:
944 divided by 138 is 6 with a remainder of 116.
Use 6 as the next digit of our solution. 
Result so far: 5906.0
Deduct 828 from 944 and we're left with 116.
Bring next digit (5) of the dividend behind the 116 and repeat the process: 1165 / 138

Let's proceed to step 7:
138 can be fit into 1165 8 times, resulting in a remainder of 61.
Record the quotient 8 as the next digit in the result. 
Result so far: 59068.0
Subtract 1104 from 1165 to get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Moving on to step 8:
138 can be fit into 610 4 times, resulting in a remainder of 58.
Use 4 as the next digit of our solution. 
Result so far: 59068.4
Subtract 552 from 610 to get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Going ahead to step 9:
138 goes into 580 4 times with a remainder of 28.
Use 4 as the next digit of our solution. 
Result so far: 59068.44
Subtracting 552 from 580 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

The final outcome is 59068.44, with a leftover of 0.028.
