Let's divide 84071440 by 401
Our goal is to divide 84071440 by 401.

Advancing to step 1:
If we divide 8 by 401, we get 0 and a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Fetch the next digit (4) from the dividend, attach it to 8 and continue: 84 / 401

On to step 2:
401 can be fit into 84 0 times, resulting in a remainder of 84.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 84, we end up with 84.
Include the next digit (0) from the dividend after 84, then repeat: 840 / 401

On to step 3:
840 divided by 401 is 2 with a remainder of 38.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtracting 802 from 840 leaves us with 38.
Include the next digit (7) from the dividend after 38, then repeat: 387 / 401

Let's proceed to step 4:
401 goes into 387 0 times with a remainder of 387.
The next digit of our result is 0. 
Result so far: 20.0
Subtract 0 from 387 to get 387.
Include the next digit (1) from the dividend after 387, then repeat: 3871 / 401

Step 5:
When dividing 3871 by 401, we get 9 with a remainder of 262.
The number 9 becomes the next digit in our result. 
Result so far: 209.0
Subtracting 3609 from 3871 leaves us with 262.
Include the next digit (4) from the dividend after 262, then repeat: 2624 / 401

Step 6:
401 goes into 2624 6 times with a remainder of 218.
The next digit of our result is 6. 
Result so far: 2096.0
If we take 2406 away from 2624, we end up with 218.
Include the next digit (4) from the dividend after 218, then repeat: 2184 / 401

On to step 7:
When dividing 2184 by 401, we get 5 with a remainder of 179.
Use 5 as the next digit of our solution. 
Result so far: 20965.0
Subtract 2005 from 2184 to get 179.
Grab the next digit (0) from the dividend, add it to 179, then carry on: 1790 / 401

On to step 8:
If we divide 1790 by 401, we get 4 and a remainder of 186.
The number 4 becomes the next digit in our result. 
Result so far: 209654.0
Subtracting 1604 from 1790 leaves us with 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

Moving on to step 9:
When dividing 1860 by 401, we get 4 with a remainder of 256.
The next digit of our result is 4. 
Result so far: 209654.4
Subtracting 1604 from 1860 leaves us with 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Going ahead to step 10:
When dividing 2560 by 401, we get 6 with a remainder of 154.
The number 6 becomes the next digit in our result. 
Result so far: 209654.46
If we take 2406 away from 2560, we end up with 154.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

On to step 11:
When dividing 1540 by 401, we get 3 with a remainder of 337.
Use 3 as the next digit of our solution. 
Result so far: 209654.463
Deduct 1203 from 1540 and we're left with 337.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3370, and continue the process.

On to step 12:
401 can be fit into 3370 8 times, resulting in a remainder of 162.
Use 8 as the next digit of our solution. 
Result so far: 209654.4638
If we take 3208 away from 3370, we end up with 162.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1620, and continue the process.

Going ahead to step 13:
401 can be fit into 1620 4 times, resulting in a remainder of 16.
Use 4 as the next digit of our solution. 
Result so far: 209654.46384
If we take 1604 away from 1620, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 14:
The number 401 fits into 160 0 times, leaving a remainder of 160.
Use 0 as the next digit of our solution. 
Result so far: 209654.46384
Deduct 0 from 160 and we're left with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Moving on to step 15:
When dividing 1600 by 401, we get 3 with a remainder of 397.
Use 3 as the next digit of our solution. 
Result so far: 209654.4638403
The remainder is 397 after subtracting 1203 from 1600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3970, and continue the process.

Going ahead to step 16:
401 can be fit into 3970 9 times, resulting in a remainder of 361.
The next digit of our result is 9. 
Result so far: 209654.46384039
Subtract 3609 from 3970 to get 361.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3610, and continue the process.

The final result is 209654.46384039 with a remainder of 3.61e-07.
