We're dividing 15878933 by 258 
Let's see how many times 258 fits into 15878933.

Step 1:
When dividing 1 by 258, we get 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 258

Advancing to step 2:
If we divide 15 by 258, we get 0 and a remainder of 15.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 15, we end up with 15.
Take the next digit (8) from the dividend and append it to 15, then repeat: 158 / 258

Let's proceed to step 3:
The number 258 fits into 158 0 times, leaving a remainder of 158.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 158, we end up with 158.
Bring next digit (7) of the dividend behind the 158 and repeat the process: 1587 / 258

On to step 4:
258 can be fit into 1587 6 times, resulting in a remainder of 39.
The next digit of our result is 6. 
Result so far: 6.0
If we take 1548 away from 1587, we end up with 39.
Grab the next digit (8) from the dividend, add it to 39, then carry on: 398 / 258

Let's proceed to step 5:
258 can be fit into 398 1 times, resulting in a remainder of 140.
The number 1 becomes the next digit in our result. 
Result so far: 61.0
If we subtract 258 from 398, we get 140.
Take the next digit (9) from the dividend and append it to 140, then repeat: 1409 / 258

Let's proceed to step 6:
258 goes into 1409 5 times with a remainder of 119.
The number 5 becomes the next digit in our result. 
Result so far: 615.0
The remainder is 119 after subtracting 1290 from 1409.
Take the next digit (3) from the dividend and append it to 119, then repeat: 1193 / 258

On to step 7:
1193 divided by 258 is 4 with a remainder of 161.
Put 4 as the next digit of the answer. 
Result so far: 6154.0
The remainder is 161 after subtracting 1032 from 1193.
Include the next digit (3) from the dividend after 161, then repeat: 1613 / 258

Advancing to step 8:
When dividing 1613 by 258, we get 6 with a remainder of 65.
Write down 6 as next digit of the result. 
Result so far: 61546.0
If we subtract 1548 from 1613, we get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Moving on to step 9:
258 can be fit into 650 2 times, resulting in a remainder of 134.
The next digit of our result is 2. 
Result so far: 61546.2
If we take 516 away from 650, we end up with 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

Let's proceed to step 10:
258 can be fit into 1340 5 times, resulting in a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 61546.25
Subtract 1290 from 1340 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 11:
When dividing 500 by 258, we get 1 with a remainder of 242.
The next digit of our result is 1. 
Result so far: 61546.251
If we subtract 258 from 500, we get 242.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2420, and continue the process.

Moving on to step 12:
258 can be fit into 2420 9 times, resulting in a remainder of 98.
The next digit of our result is 9. 
Result so far: 61546.2519
Subtract 2322 from 2420 to get 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Let's proceed to step 13:
The number 258 fits into 980 3 times, leaving a remainder of 206.
Use 3 as the next digit of our solution. 
Result so far: 61546.25193
Subtract 774 from 980 to get 206.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2060, and continue the process.

Let's proceed to step 14:
2060 divided by 258 is 7 with a remainder of 254.
The number 7 becomes the next digit in our result. 
Result so far: 61546.251937
If we take 1806 away from 2060, we end up with 254.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2540, and continue the process.

On to step 15:
The number 258 fits into 2540 9 times, leaving a remainder of 218.
The number 9 becomes the next digit in our result. 
Result so far: 61546.2519379
If we subtract 2322 from 2540, we get 218.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

Let's proceed to step 16:
The number 258 fits into 2180 8 times, leaving a remainder of 116.
The next digit of our result is 8. 
Result so far: 61546.25193798
The remainder is 116 after subtracting 2064 from 2180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

The quotient of the division is 61546.25193798, and the remainder is 1.16e-07.
