Let's divide 43631229 by 401
We want to divide 43631229 by 401.

Step 1:
If we divide 4 by 401, we get 0 and a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Grab the next digit (3) from the dividend, add it to 4, then carry on: 43 / 401

Moving on to step 2:
401 goes into 43 0 times with a remainder of 43.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 43, we end up with 43.
Include the next digit (6) from the dividend after 43, then repeat: 436 / 401

Step 3:
401 goes into 436 1 times with a remainder of 35.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 401 from 436, we get 35.
Take the next digit (3) from the dividend and append it to 35, then repeat: 353 / 401

Let's proceed to step 4:
401 can be fit into 353 0 times, resulting in a remainder of 353.
Write down 0 as next digit of the result. 
Result so far: 10.0
Deduct 0 from 353 and we're left with 353.
Include the next digit (1) from the dividend after 353, then repeat: 3531 / 401

Let's proceed to step 5:
When dividing 3531 by 401, we get 8 with a remainder of 323.
The next digit of our result is 8. 
Result so far: 108.0
Subtracting 3208 from 3531 leaves us with 323.
Grab the next digit (2) from the dividend, add it to 323, then carry on: 3232 / 401

Advancing to step 6:
401 can be fit into 3232 8 times, resulting in a remainder of 24.
Put 8 as the next digit of the answer. 
Result so far: 1088.0
Subtracting 3208 from 3232 leaves us with 24.
Include the next digit (2) from the dividend after 24, then repeat: 242 / 401

Advancing to step 7:
401 can be fit into 242 0 times, resulting in a remainder of 242.
Write down 0 as next digit of the result. 
Result so far: 10880.0
Subtract 0 from 242 to get 242.
Grab the next digit (9) from the dividend, add it to 242, then carry on: 2429 / 401

Advancing to step 8:
401 can be fit into 2429 6 times, resulting in a remainder of 23.
Put 6 as the next digit of the answer. 
Result so far: 108806.0
If we take 2406 away from 2429, we end up with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Moving on to step 9:
230 divided by 401 is 0 with a remainder of 230.
Write down 0 as next digit of the result. 
Result so far: 108806.0
Subtracting 0 from 230 leaves us with 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Advancing to step 10:
When dividing 2300 by 401, we get 5 with a remainder of 295.
The number 5 becomes the next digit in our result. 
Result so far: 108806.05
Subtract 2005 from 2300 to get 295.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2950, and continue the process.

On to step 11:
When dividing 2950 by 401, we get 7 with a remainder of 143.
Put 7 as the next digit of the answer. 
Result so far: 108806.057
If we take 2807 away from 2950, we end up with 143.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1430, and continue the process.

Advancing to step 12:
401 goes into 1430 3 times with a remainder of 227.
Use 3 as the next digit of our solution. 
Result so far: 108806.0573
Subtracting 1203 from 1430 leaves us with 227.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2270, and continue the process.

Step 13:
401 goes into 2270 5 times with a remainder of 265.
Put 5 as the next digit of the answer. 
Result so far: 108806.05735
Subtracting 2005 from 2270 leaves us with 265.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2650, and continue the process.

Step 14:
The number 401 fits into 2650 6 times, leaving a remainder of 244.
Use 6 as the next digit of our solution. 
Result so far: 108806.057356
Subtract 2406 from 2650 to get 244.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

On to step 15:
2440 divided by 401 is 6 with a remainder of 34.
The next digit of our result is 6. 
Result so far: 108806.0573566
The remainder is 34 after subtracting 2406 from 2440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

The final outcome is 108806.0573566, with a leftover of 3.4e-07.
