73115154 ÷ 401 
Our goal is to divide 73115154 by 401.

Let's proceed to step 1:
The number 401 fits into 7 0 times, leaving a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Include the next digit (3) from the dividend after 7, then repeat: 73 / 401

On to step 2:
401 can be fit into 73 0 times, resulting in a remainder of 73.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 73, we get 73.
Append the next digit (1) from the dividend to 73 and continue with: 731 / 401

Step 3:
731 divided by 401 is 1 with a remainder of 330.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 401 from 731 and we're left with 330.
Bring next digit (1) of the dividend behind the 330 and repeat the process: 3301 / 401

Moving on to step 4:
3301 divided by 401 is 8 with a remainder of 93.
Record the quotient 8 as the next digit in the result. 
Result so far: 18.0
Subtracting 3208 from 3301 leaves us with 93.
Bring next digit (5) of the dividend behind the 93 and repeat the process: 935 / 401

Going ahead to step 5:
401 goes into 935 2 times with a remainder of 133.
Write down 2 as next digit of the result. 
Result so far: 182.0
Subtracting 802 from 935 leaves us with 133.
Bring next digit (1) of the dividend behind the 133 and repeat the process: 1331 / 401

Going ahead to step 6:
If we divide 1331 by 401, we get 3 and a remainder of 128.
Write down 3 as next digit of the result. 
Result so far: 1823.0
Subtracting 1203 from 1331 leaves us with 128.
Append the next digit (5) from the dividend to 128 and continue with: 1285 / 401

Moving on to step 7:
401 goes into 1285 3 times with a remainder of 82.
The next digit of our result is 3. 
Result so far: 18233.0
Subtracting 1203 from 1285 leaves us with 82.
Include the next digit (4) from the dividend after 82, then repeat: 824 / 401

Let's proceed to step 8:
401 can be fit into 824 2 times, resulting in a remainder of 22.
The number 2 becomes the next digit in our result. 
Result so far: 182332.0
The remainder is 22 after subtracting 802 from 824.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 9:
220 divided by 401 is 0 with a remainder of 220.
The next digit of our result is 0. 
Result so far: 182332.0
Deduct 0 from 220 and we're left with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Moving on to step 10:
401 can be fit into 2200 5 times, resulting in a remainder of 195.
The next digit of our result is 5. 
Result so far: 182332.05
Deduct 2005 from 2200 and we're left with 195.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

Step 11:
401 can be fit into 1950 4 times, resulting in a remainder of 346.
Use 4 as the next digit of our solution. 
Result so far: 182332.054
Subtracting 1604 from 1950 leaves us with 346.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3460, and continue the process.

Let's proceed to step 12:
If we divide 3460 by 401, we get 8 and a remainder of 252.
The next digit of our result is 8. 
Result so far: 182332.0548
Deduct 3208 from 3460 and we're left with 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

Let's proceed to step 13:
401 goes into 2520 6 times with a remainder of 114.
The number 6 becomes the next digit in our result. 
Result so far: 182332.05486
Subtracting 2406 from 2520 leaves us with 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

Step 14:
When dividing 1140 by 401, we get 2 with a remainder of 338.
Write down 2 as next digit of the result. 
Result so far: 182332.054862
Deduct 802 from 1140 and we're left with 338.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3380, and continue the process.

Advancing to step 15:
401 can be fit into 3380 8 times, resulting in a remainder of 172.
The number 8 becomes the next digit in our result. 
Result so far: 182332.0548628
If we subtract 3208 from 3380, we get 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Advancing to step 16:
When dividing 1720 by 401, we get 4 with a remainder of 116.
The next digit of our result is 4. 
Result so far: 182332.05486284
If we take 1604 away from 1720, we end up with 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

After the division, we end up with 182332.05486284 and a remainder of 1.16e-07.
