We're dividing 75029243 by 401 
Our goal is to divide 75029243 by 401.

Step 1:
The number 401 fits into 7 0 times, leaving a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Include the next digit (5) from the dividend after 7, then repeat: 75 / 401

Moving on to step 2:
401 can be fit into 75 0 times, resulting in a remainder of 75.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 75 and we're left with 75.
Grab the next digit (0) from the dividend, add it to 75, then carry on: 750 / 401

Going ahead to step 3:
401 can be fit into 750 1 times, resulting in a remainder of 349.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 401 from 750 leaves us with 349.
Append the next digit (2) from the dividend to 349 and continue with: 3492 / 401

On to step 4:
401 goes into 3492 8 times with a remainder of 284.
The number 8 becomes the next digit in our result. 
Result so far: 18.0
Deduct 3208 from 3492 and we're left with 284.
Bring next digit (9) of the dividend behind the 284 and repeat the process: 2849 / 401

Step 5:
401 can be fit into 2849 7 times, resulting in a remainder of 42.
Use 7 as the next digit of our solution. 
Result so far: 187.0
Deduct 2807 from 2849 and we're left with 42.
Bring next digit (2) of the dividend behind the 42 and repeat the process: 422 / 401

Advancing to step 6:
422 divided by 401 is 1 with a remainder of 21.
Use 1 as the next digit of our solution. 
Result so far: 1871.0
If we subtract 401 from 422, we get 21.
Include the next digit (4) from the dividend after 21, then repeat: 214 / 401

Advancing to step 7:
214 divided by 401 is 0 with a remainder of 214.
The number 0 becomes the next digit in our result. 
Result so far: 18710.0
If we take 0 away from 214, we end up with 214.
Append the next digit (3) from the dividend to 214 and continue with: 2143 / 401

Step 8:
If we divide 2143 by 401, we get 5 and a remainder of 138.
Record the quotient 5 as the next digit in the result. 
Result so far: 187105.0
Subtract 2005 from 2143 to get 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

Moving on to step 9:
401 can be fit into 1380 3 times, resulting in a remainder of 177.
Put 3 as the next digit of the answer. 
Result so far: 187105.3
Subtracting 1203 from 1380 leaves us with 177.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1770, and continue the process.

Going ahead to step 10:
When dividing 1770 by 401, we get 4 with a remainder of 166.
Use 4 as the next digit of our solution. 
Result so far: 187105.34
Subtracting 1604 from 1770 leaves us with 166.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

Advancing to step 11:
401 goes into 1660 4 times with a remainder of 56.
Write down 4 as next digit of the result. 
Result so far: 187105.344
Deduct 1604 from 1660 and we're left with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Our division results in 187105.344 with a remaining 0.0056.
