15477861 ÷ 428 
We want to figure out the number of times 15477861 can be divided by 428.

Moving on to step 1:
When dividing 1 by 428, we get 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 428

Going ahead to step 2:
If we divide 15 by 428, 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.
Append the next digit (4) from the dividend to 15 and continue with: 154 / 428

Moving on to step 3:
When dividing 154 by 428, we get 0 with a remainder of 154.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 154 to get 154.
Take the next digit (7) from the dividend and append it to 154, then repeat: 1547 / 428

Let's proceed to step 4:
428 can be fit into 1547 3 times, resulting in a remainder of 263.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we take 1284 away from 1547, we end up with 263.
Append the next digit (7) from the dividend to 263 and continue with: 2637 / 428

Moving on to step 5:
When dividing 2637 by 428, we get 6 with a remainder of 69.
Use 6 as the next digit of our solution. 
Result so far: 36.0
The remainder is 69 after subtracting 2568 from 2637.
Append the next digit (8) from the dividend to 69 and continue with: 698 / 428

Let's proceed to step 6:
428 goes into 698 1 times with a remainder of 270.
Put 1 as the next digit of the answer. 
Result so far: 361.0
Deduct 428 from 698 and we're left with 270.
Grab the next digit (6) from the dividend, add it to 270, then carry on: 2706 / 428

On to step 7:
428 can be fit into 2706 6 times, resulting in a remainder of 138.
Record the quotient 6 as the next digit in the result. 
Result so far: 3616.0
If we subtract 2568 from 2706, we get 138.
Include the next digit (1) from the dividend after 138, then repeat: 1381 / 428

Advancing to step 8:
The number 428 fits into 1381 3 times, leaving a remainder of 97.
Use 3 as the next digit of our solution. 
Result so far: 36163.0
Subtract 1284 from 1381 to get 97.
Since there are no more digits in the dividend, we add a zero to the remainder making it 970, and continue the process.

Moving on to step 9:
970 divided by 428 is 2 with a remainder of 114.
Record the quotient 2 as the next digit in the result. 
Result so far: 36163.2
Subtract 856 from 970 to get 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 10:
If we divide 1140 by 428, we get 2 and a remainder of 284.
The next digit of our result is 2. 
Result so far: 36163.22
If we take 856 away from 1140, we end up with 284.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

The quotient of the division is 36163.22, and the remainder is 0.284.
