Let's divide 15152783 by 401
We want to figure out the number of times 15152783 can be divided by 401.

Advancing to step 1:
If we divide 1 by 401, we get 0 and a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 401

Let's proceed to step 2:
401 goes into 15 0 times with a remainder of 15.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 15, we get 15.
Fetch the next digit (1) from the dividend, attach it to 15 and continue: 151 / 401

Step 3:
When dividing 151 by 401, we get 0 with a remainder of 151.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 151 leaves us with 151.
Grab the next digit (5) from the dividend, add it to 151, then carry on: 1515 / 401

Advancing to step 4:
401 can be fit into 1515 3 times, resulting in a remainder of 312.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtract 1203 from 1515 to get 312.
Include the next digit (2) from the dividend after 312, then repeat: 3122 / 401

Let's proceed to step 5:
When dividing 3122 by 401, we get 7 with a remainder of 315.
The next digit of our result is 7. 
Result so far: 37.0
If we take 2807 away from 3122, we end up with 315.
Take the next digit (7) from the dividend and append it to 315, then repeat: 3157 / 401

Let's proceed to step 6:
401 can be fit into 3157 7 times, resulting in a remainder of 350.
The number 7 becomes the next digit in our result. 
Result so far: 377.0
Subtract 2807 from 3157 to get 350.
Include the next digit (8) from the dividend after 350, then repeat: 3508 / 401

Going ahead to step 7:
If we divide 3508 by 401, we get 8 and a remainder of 300.
Write down 8 as next digit of the result. 
Result so far: 3778.0
If we subtract 3208 from 3508, we get 300.
Grab the next digit (3) from the dividend, add it to 300, then carry on: 3003 / 401

Going ahead to step 8:
The number 401 fits into 3003 7 times, leaving a remainder of 196.
Use 7 as the next digit of our solution. 
Result so far: 37787.0
If we take 2807 away from 3003, we end up with 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

Advancing to step 9:
1960 divided by 401 is 4 with a remainder of 356.
Use 4 as the next digit of our solution. 
Result so far: 37787.4
Deduct 1604 from 1960 and we're left with 356.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3560, and continue the process.

Step 10:
The number 401 fits into 3560 8 times, leaving a remainder of 352.
Use 8 as the next digit of our solution. 
Result so far: 37787.48
If we take 3208 away from 3560, we end up with 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

Going ahead to step 11:
The number 401 fits into 3520 8 times, leaving a remainder of 312.
Write down 8 as next digit of the result. 
Result so far: 37787.488
Subtracting 3208 from 3520 leaves us with 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

Our division results in 37787.488 with a remaining 0.0312.
