We look at the division of 69815398 by 401 
We want to divide 69815398 by 401.

Going ahead to step 1:
401 goes into 6 0 times with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Append the next digit (9) from the dividend to 6 and continue with: 69 / 401

Step 2:
401 can be fit into 69 0 times, resulting in a remainder of 69.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 69, we end up with 69.
Include the next digit (8) from the dividend after 69, then repeat: 698 / 401

Step 3:
The number 401 fits into 698 1 times, leaving a remainder of 297.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 401 away from 698, we end up with 297.
Bring next digit (1) of the dividend behind the 297 and repeat the process: 2971 / 401

Step 4:
When dividing 2971 by 401, we get 7 with a remainder of 164.
The next digit of our result is 7. 
Result so far: 17.0
Deduct 2807 from 2971 and we're left with 164.
Take the next digit (5) from the dividend and append it to 164, then repeat: 1645 / 401

Let's proceed to step 5:
The number 401 fits into 1645 4 times, leaving a remainder of 41.
The next digit of our result is 4. 
Result so far: 174.0
Subtract 1604 from 1645 to get 41.
Append the next digit (3) from the dividend to 41 and continue with: 413 / 401

Advancing to step 6:
When dividing 413 by 401, we get 1 with a remainder of 12.
Record the quotient 1 as the next digit in the result. 
Result so far: 1741.0
Subtract 401 from 413 to get 12.
Fetch the next digit (9) from the dividend, attach it to 12 and continue: 129 / 401

Moving on to step 7:
401 can be fit into 129 0 times, resulting in a remainder of 129.
Use 0 as the next digit of our solution. 
Result so far: 17410.0
Subtract 0 from 129 to get 129.
Include the next digit (8) from the dividend after 129, then repeat: 1298 / 401

Moving on to step 8:
1298 divided by 401 is 3 with a remainder of 95.
The number 3 becomes the next digit in our result. 
Result so far: 174103.0
If we take 1203 away from 1298, we end up with 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Moving on to step 9:
When dividing 950 by 401, we get 2 with a remainder of 148.
The number 2 becomes the next digit in our result. 
Result so far: 174103.2
Subtract 802 from 950 to get 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Let's proceed to step 10:
When dividing 1480 by 401, we get 3 with a remainder of 277.
Write down 3 as next digit of the result. 
Result so far: 174103.23
If we take 1203 away from 1480, we end up with 277.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2770, and continue the process.

Let's proceed to step 11:
The number 401 fits into 2770 6 times, leaving a remainder of 364.
Record the quotient 6 as the next digit in the result. 
Result so far: 174103.236
Subtracting 2406 from 2770 leaves us with 364.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

Let's proceed to step 12:
401 goes into 3640 9 times with a remainder of 31.
The next digit of our result is 9. 
Result so far: 174103.2369
If we take 3609 away from 3640, we end up with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Going ahead to step 13:
401 goes into 310 0 times with a remainder of 310.
Use 0 as the next digit of our solution. 
Result so far: 174103.2369
If we subtract 0 from 310, we get 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

On to step 14:
3100 divided by 401 is 7 with a remainder of 293.
Put 7 as the next digit of the answer. 
Result so far: 174103.236907
Subtracting 2807 from 3100 leaves us with 293.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2930, and continue the process.

Going ahead to step 15:
If we divide 2930 by 401, we get 7 and a remainder of 123.
Write down 7 as next digit of the result. 
Result so far: 174103.2369077
If we take 2807 away from 2930, we end up with 123.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1230, and continue the process.

After the division, we end up with 174103.2369077 and a remainder of 1.23e-06.
