We divide 7521888 by 401
Our goal is to divide 7521888 by 401.

Going ahead to step 1:
7 divided by 401 is 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Append the next digit (5) from the dividend to 7 and continue with: 75 / 401

On to step 2:
If we divide 75 by 401, we get 0 and a remainder of 75.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 75 leaves us with 75.
Include the next digit (2) from the dividend after 75, then repeat: 752 / 401

Moving on to step 3:
If we divide 752 by 401, we get 1 and a remainder of 351.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 401 from 752 to get 351.
Include the next digit (1) from the dividend after 351, then repeat: 3511 / 401

Step 4:
3511 divided by 401 is 8 with a remainder of 303.
The next digit of our result is 8. 
Result so far: 18.0
If we take 3208 away from 3511, we end up with 303.
Include the next digit (8) from the dividend after 303, then repeat: 3038 / 401

Step 5:
The number 401 fits into 3038 7 times, leaving a remainder of 231.
The next digit of our result is 7. 
Result so far: 187.0
Subtracting 2807 from 3038 leaves us with 231.
Grab the next digit (8) from the dividend, add it to 231, then carry on: 2318 / 401

Step 6:
The number 401 fits into 2318 5 times, leaving a remainder of 313.
Put 5 as the next digit of the answer. 
Result so far: 1875.0
If we take 2005 away from 2318, we end up with 313.
Include the next digit (8) from the dividend after 313, then repeat: 3138 / 401

Going ahead to step 7:
401 can be fit into 3138 7 times, resulting in a remainder of 331.
Put 7 as the next digit of the answer. 
Result so far: 18757.0
Deduct 2807 from 3138 and we're left with 331.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3310, and continue the process.

Moving on to step 8:
The number 401 fits into 3310 8 times, leaving a remainder of 102.
Put 8 as the next digit of the answer. 
Result so far: 18757.8
Subtract 3208 from 3310 to get 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

Moving on to step 9:
401 goes into 1020 2 times with a remainder of 218.
The next digit of our result is 2. 
Result so far: 18757.82
Subtract 802 from 1020 to get 218.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

Moving on to step 10:
The number 401 fits into 2180 5 times, leaving a remainder of 175.
The next digit of our result is 5. 
Result so far: 18757.825
The remainder is 175 after subtracting 2005 from 2180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Let's proceed to step 11:
If we divide 1750 by 401, we get 4 and a remainder of 146.
Write down 4 as next digit of the result. 
Result so far: 18757.8254
The remainder is 146 after subtracting 1604 from 1750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

Let's proceed to step 12:
1460 divided by 401 is 3 with a remainder of 257.
Use 3 as the next digit of our solution. 
Result so far: 18757.82543
Subtracting 1203 from 1460 leaves us with 257.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2570, and continue the process.

Advancing to step 13:
When dividing 2570 by 401, we get 6 with a remainder of 164.
The next digit of our result is 6. 
Result so far: 18757.825436
Subtracting 2406 from 2570 leaves us with 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Advancing to step 14:
401 can be fit into 1640 4 times, resulting in a remainder of 36.
Use 4 as the next digit of our solution. 
Result so far: 18757.8254364
Subtracting 1604 from 1640 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 15:
When dividing 360 by 401, we get 0 with a remainder of 360.
Record the quotient 0 as the next digit in the result. 
Result so far: 18757.8254364
Subtracting 0 from 360 leaves us with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Our division results in 18757.8254364 with a remaining 3.6e-07.
