Let's divide 8274352 by 401
The aim is to understand the frequency of 401 in 8274352.

On to step 1:
401 goes into 8 0 times with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Bring next digit (2) of the dividend behind the 8 and repeat the process: 82 / 401

Advancing to step 2:
401 can be fit into 82 0 times, resulting in a remainder of 82.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 82 and we're left with 82.
Include the next digit (7) from the dividend after 82, then repeat: 827 / 401

Step 3:
The number 401 fits into 827 2 times, leaving a remainder of 25.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtract 802 from 827 to get 25.
Fetch the next digit (4) from the dividend, attach it to 25 and continue: 254 / 401

Step 4:
If we divide 254 by 401, we get 0 and a remainder of 254.
The next digit of our result is 0. 
Result so far: 20.0
Subtracting 0 from 254 leaves us with 254.
Include the next digit (3) from the dividend after 254, then repeat: 2543 / 401

Going ahead to step 5:
2543 divided by 401 is 6 with a remainder of 137.
Record the quotient 6 as the next digit in the result. 
Result so far: 206.0
If we subtract 2406 from 2543, we get 137.
Include the next digit (5) from the dividend after 137, then repeat: 1375 / 401

Step 6:
1375 divided by 401 is 3 with a remainder of 172.
Record the quotient 3 as the next digit in the result. 
Result so far: 2063.0
The remainder is 172 after subtracting 1203 from 1375.
Include the next digit (2) from the dividend after 172, then repeat: 1722 / 401

Advancing to step 7:
1722 divided by 401 is 4 with a remainder of 118.
Use 4 as the next digit of our solution. 
Result so far: 20634.0
Subtracting 1604 from 1722 leaves us with 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

Moving on to step 8:
401 can be fit into 1180 2 times, resulting in a remainder of 378.
Write down 2 as next digit of the result. 
Result so far: 20634.2
Subtract 802 from 1180 to get 378.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3780, and continue the process.

On to step 9:
3780 divided by 401 is 9 with a remainder of 171.
Use 9 as the next digit of our solution. 
Result so far: 20634.29
Subtracting 3609 from 3780 leaves us with 171.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1710, and continue the process.

Step 10:
401 can be fit into 1710 4 times, resulting in a remainder of 106.
Use 4 as the next digit of our solution. 
Result so far: 20634.294
Subtract 1604 from 1710 to get 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

On to step 11:
401 goes into 1060 2 times with a remainder of 258.
Write down 2 as next digit of the result. 
Result so far: 20634.2942
The remainder is 258 after subtracting 802 from 1060.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2580, and continue the process.

Going ahead to step 12:
When dividing 2580 by 401, we get 6 with a remainder of 174.
The next digit of our result is 6. 
Result so far: 20634.29426
The remainder is 174 after subtracting 2406 from 2580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

Moving on to step 13:
The number 401 fits into 1740 4 times, leaving a remainder of 136.
Use 4 as the next digit of our solution. 
Result so far: 20634.294264
The remainder is 136 after subtracting 1604 from 1740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Let's proceed to step 14:
401 goes into 1360 3 times with a remainder of 157.
Write down 3 as next digit of the result. 
Result so far: 20634.2942643
Deduct 1203 from 1360 and we're left with 157.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1570, and continue the process.

Moving on to step 15:
401 can be fit into 1570 3 times, resulting in a remainder of 367.
The next digit of our result is 3. 
Result so far: 20634.29426433
If we take 1203 away from 1570, we end up with 367.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3670, and continue the process.

The quotient of the division is 20634.29426433, and the remainder is 3.67e-07.
