We're dividing 16101052 by 42 
Our goal is to divide 16101052 by 42.

Going ahead to step 1:
The number 42 fits into 1 0 times, leaving a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Append the next digit (6) from the dividend to 1 and continue with: 16 / 42

Going ahead to step 2:
42 can be fit into 16 0 times, resulting in a remainder of 16.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 16, we get 16.
Bring next digit (1) of the dividend behind the 16 and repeat the process: 161 / 42

Going ahead to step 3:
The number 42 fits into 161 3 times, leaving a remainder of 35.
Write down 3 as next digit of the result. 
Result so far: 3.0
Deduct 126 from 161 and we're left with 35.
Fetch the next digit (0) from the dividend, attach it to 35 and continue: 350 / 42

Going ahead to step 4:
350 divided by 42 is 8 with a remainder of 14.
The next digit of our result is 8. 
Result so far: 38.0
If we subtract 336 from 350, we get 14.
Grab the next digit (1) from the dividend, add it to 14, then carry on: 141 / 42

Going ahead to step 5:
If we divide 141 by 42, we get 3 and a remainder of 15.
Record the quotient 3 as the next digit in the result. 
Result so far: 383.0
Subtracting 126 from 141 leaves us with 15.
Fetch the next digit (0) from the dividend, attach it to 15 and continue: 150 / 42

Step 6:
42 goes into 150 3 times with a remainder of 24.
Record the quotient 3 as the next digit in the result. 
Result so far: 3833.0
Subtract 126 from 150 to get 24.
Fetch the next digit (5) from the dividend, attach it to 24 and continue: 245 / 42

Going ahead to step 7:
If we divide 245 by 42, we get 5 and a remainder of 35.
The number 5 becomes the next digit in our result. 
Result so far: 38335.0
If we take 210 away from 245, we end up with 35.
Bring next digit (2) of the dividend behind the 35 and repeat the process: 352 / 42

Let's proceed to step 8:
If we divide 352 by 42, we get 8 and a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 383358.0
The remainder is 16 after subtracting 336 from 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 9:
42 goes into 160 3 times with a remainder of 34.
Record the quotient 3 as the next digit in the result. 
Result so far: 383358.3
If we take 126 away from 160, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 10:
If we divide 340 by 42, we get 8 and a remainder of 4.
The next digit of our result is 8. 
Result so far: 383358.38
Subtracting 336 from 340 leaves us 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.

Advancing to step 11:
If we divide 40 by 42, we get 0 and a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 383358.38
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 12:
When dividing 400 by 42, we get 9 with a remainder of 22.
The number 9 becomes the next digit in our result. 
Result so far: 383358.3809
Subtracting 378 from 400 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.

Step 13:
When dividing 220 by 42, we get 5 with a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 383358.38095
If we subtract 210 from 220, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 14:
42 goes into 100 2 times with a remainder of 16.
The next digit of our result is 2. 
Result so far: 383358.380952
Deduct 84 from 100 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 15:
42 can be fit into 160 3 times, resulting in a remainder of 34.
Use 3 as the next digit of our solution. 
Result so far: 383358.3809523
If we take 126 away from 160, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 16:
42 can be fit into 340 8 times, resulting in a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 383358.38095238
Deduct 336 from 340 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.

The final result is 383358.38095238 with a remainder of 4e-09.
