Let's divide 42122462 by 138
We want to divide 42122462 by 138.

Step 1:
If we divide 4 by 138, we get 0 and a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 138

On to step 2:
42 divided by 138 is 0 with a remainder of 42.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 42 to get 42.
Bring next digit (1) of the dividend behind the 42 and repeat the process: 421 / 138

Going ahead to step 3:
When dividing 421 by 138, we get 3 with a remainder of 7.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we subtract 414 from 421, we get 7.
Bring next digit (2) of the dividend behind the 7 and repeat the process: 72 / 138

On to step 4:
138 goes into 72 0 times with a remainder of 72.
The next digit of our result is 0. 
Result so far: 30.0
If we take 0 away from 72, we end up with 72.
Fetch the next digit (2) from the dividend, attach it to 72 and continue: 722 / 138

Let's proceed to step 5:
722 divided by 138 is 5 with a remainder of 32.
Put 5 as the next digit of the answer. 
Result so far: 305.0
Deduct 690 from 722 and we're left with 32.
Append the next digit (4) from the dividend to 32 and continue with: 324 / 138

Going ahead to step 6:
324 divided by 138 is 2 with a remainder of 48.
Use 2 as the next digit of our solution. 
Result so far: 3052.0
If we subtract 276 from 324, we get 48.
Append the next digit (6) from the dividend to 48 and continue with: 486 / 138

On to step 7:
If we divide 486 by 138, we get 3 and a remainder of 72.
Use 3 as the next digit of our solution. 
Result so far: 30523.0
If we subtract 414 from 486, we get 72.
Take the next digit (2) from the dividend and append it to 72, then repeat: 722 / 138

Moving on to step 8:
722 divided by 138 is 5 with a remainder of 32.
Record the quotient 5 as the next digit in the result. 
Result so far: 305235.0
If we take 690 away from 722, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 9:
320 divided by 138 is 2 with a remainder of 44.
The number 2 becomes the next digit in our result. 
Result so far: 305235.2
If we subtract 276 from 320, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 10:
If we divide 440 by 138, we get 3 and a remainder of 26.
Put 3 as the next digit of the answer. 
Result so far: 305235.23
Deduct 414 from 440 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 11:
If we divide 260 by 138, we get 1 and a remainder of 122.
The number 1 becomes the next digit in our result. 
Result so far: 305235.231
The remainder is 122 after subtracting 138 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

On to step 12:
138 can be fit into 1220 8 times, resulting in a remainder of 116.
Put 8 as the next digit of the answer. 
Result so far: 305235.2318
Subtract 1104 from 1220 to get 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Advancing to step 13:
If we divide 1160 by 138, we get 8 and a remainder of 56.
The number 8 becomes the next digit in our result. 
Result so far: 305235.23188
The remainder is 56 after subtracting 1104 from 1160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

The quotient of the division is 305235.23188, and the remainder is 5.6e-05.
