We look at the division of 42002144 by 401 
We're looking to find how many times 401 goes into 42002144.

Moving on to step 1:
401 goes into 4 0 times with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 401

Advancing to step 2:
If we divide 42 by 401, we get 0 and a remainder of 42.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 42, we end up with 42.
Grab the next digit (0) from the dividend, add it to 42, then carry on: 420 / 401

On to step 3:
When dividing 420 by 401, we get 1 with a remainder of 19.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 401 away from 420, we end up with 19.
Grab the next digit (0) from the dividend, add it to 19, then carry on: 190 / 401

On to step 4:
The number 401 fits into 190 0 times, leaving a remainder of 190.
Put 0 as the next digit of the answer. 
Result so far: 10.0
If we subtract 0 from 190, we get 190.
Fetch the next digit (2) from the dividend, attach it to 190 and continue: 1902 / 401

Moving on to step 5:
401 can be fit into 1902 4 times, resulting in a remainder of 298.
Put 4 as the next digit of the answer. 
Result so far: 104.0
The remainder is 298 after subtracting 1604 from 1902.
Include the next digit (1) from the dividend after 298, then repeat: 2981 / 401

Step 6:
When dividing 2981 by 401, we get 7 with a remainder of 174.
The next digit of our result is 7. 
Result so far: 1047.0
Subtracting 2807 from 2981 leaves us with 174.
Append the next digit (4) from the dividend to 174 and continue with: 1744 / 401

Step 7:
The number 401 fits into 1744 4 times, leaving a remainder of 140.
Write down 4 as next digit of the result. 
Result so far: 10474.0
Subtract 1604 from 1744 to get 140.
Include the next digit (4) from the dividend after 140, then repeat: 1404 / 401

Moving on to step 8:
If we divide 1404 by 401, we get 3 and a remainder of 201.
Put 3 as the next digit of the answer. 
Result so far: 104743.0
Deduct 1203 from 1404 and we're left with 201.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2010, and continue the process.

Moving on to step 9:
401 can be fit into 2010 5 times, resulting in a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 104743.5
If we subtract 2005 from 2010, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 10:
When dividing 50 by 401, we get 0 with a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 104743.5
Deduct 0 from 50 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 11:
401 goes into 500 1 times with a remainder of 99.
Record the quotient 1 as the next digit in the result. 
Result so far: 104743.501
If we take 401 away from 500, we end up with 99.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

Let's proceed to step 12:
401 goes into 990 2 times with a remainder of 188.
Record the quotient 2 as the next digit in the result. 
Result so far: 104743.5012
Subtracting 802 from 990 leaves us with 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Step 13:
The number 401 fits into 1880 4 times, leaving a remainder of 276.
Write down 4 as next digit of the result. 
Result so far: 104743.50124
The remainder is 276 after subtracting 1604 from 1880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

Advancing to step 14:
When dividing 2760 by 401, we get 6 with a remainder of 354.
Record the quotient 6 as the next digit in the result. 
Result so far: 104743.501246
If we take 2406 away from 2760, we end up with 354.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3540, and continue the process.

Let's proceed to step 15:
The number 401 fits into 3540 8 times, leaving a remainder of 332.
The number 8 becomes the next digit in our result. 
Result so far: 104743.5012468
Deduct 3208 from 3540 and we're left with 332.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3320, and continue the process.

Step 16:
3320 divided by 401 is 8 with a remainder of 112.
Use 8 as the next digit of our solution. 
Result so far: 104743.50124688
If we subtract 3208 from 3320, 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.

Our division results in 104743.50124688 with a remaining 1.12e-07.
