1527220 ÷ 401 
Let's see how many times 401 fits into 1527220.

Step 1:
401 can be fit into 1 0 times, resulting in a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 401

On to step 2:
If we divide 15 by 401, we get 0 and a remainder of 15.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 15, we end up with 15.
Bring next digit (2) of the dividend behind the 15 and repeat the process: 152 / 401

Let's proceed to step 3:
401 can be fit into 152 0 times, resulting in a remainder of 152.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 152, we get 152.
Fetch the next digit (7) from the dividend, attach it to 152 and continue: 1527 / 401

Advancing to step 4:
When dividing 1527 by 401, we get 3 with a remainder of 324.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we take 1203 away from 1527, we end up with 324.
Take the next digit (2) from the dividend and append it to 324, then repeat: 3242 / 401

On to step 5:
401 goes into 3242 8 times with a remainder of 34.
The number 8 becomes the next digit in our result. 
Result so far: 38.0
Subtracting 3208 from 3242 leaves us with 34.
Grab the next digit (2) from the dividend, add it to 34, then carry on: 342 / 401

Moving on to step 6:
If we divide 342 by 401, we get 0 and a remainder of 342.
Use 0 as the next digit of our solution. 
Result so far: 380.0
If we take 0 away from 342, we end up with 342.
Bring next digit (0) of the dividend behind the 342 and repeat the process: 3420 / 401

Going ahead to step 7:
401 goes into 3420 8 times with a remainder of 212.
Record the quotient 8 as the next digit in the result. 
Result so far: 3808.0
If we take 3208 away from 3420, we end up with 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

Let's proceed to step 8:
401 can be fit into 2120 5 times, resulting in a remainder of 115.
Put 5 as the next digit of the answer. 
Result so far: 3808.5
Deduct 2005 from 2120 and we're left with 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Moving on to step 9:
401 can be fit into 1150 2 times, resulting in a remainder of 348.
Put 2 as the next digit of the answer. 
Result so far: 3808.52
Subtracting 802 from 1150 leaves us with 348.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3480, and continue the process.

On to step 10:
The number 401 fits into 3480 8 times, leaving a remainder of 272.
Put 8 as the next digit of the answer. 
Result so far: 3808.528
If we take 3208 away from 3480, we end up with 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

Let's proceed to step 11:
401 goes into 2720 6 times with a remainder of 314.
Record the quotient 6 as the next digit in the result. 
Result so far: 3808.5286
Subtracting 2406 from 2720 leaves us with 314.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3140, and continue the process.

Going ahead to step 12:
401 goes into 3140 7 times with a remainder of 333.
Record the quotient 7 as the next digit in the result. 
Result so far: 3808.52867
If we subtract 2807 from 3140, we get 333.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3330, and continue the process.

Advancing to step 13:
If we divide 3330 by 401, we get 8 and a remainder of 122.
Record the quotient 8 as the next digit in the result. 
Result so far: 3808.528678
The remainder is 122 after subtracting 3208 from 3330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

On to step 14:
When dividing 1220 by 401, we get 3 with a remainder of 17.
Use 3 as the next digit of our solution. 
Result so far: 3808.5286783
Subtracting 1203 from 1220 leaves us with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Let's proceed to step 15:
The number 401 fits into 170 0 times, leaving a remainder of 170.
Put 0 as the next digit of the answer. 
Result so far: 3808.5286783
If we take 0 away from 170, we end up with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

The final outcome is 3808.5286783, with a leftover of 1.7e-07.
