Let's divide 53404672 by 258
We want to divide 53404672 by 258.

Advancing to step 1:
258 can be fit into 5 0 times, resulting in a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Grab the next digit (3) from the dividend, add it to 5, then carry on: 53 / 258

Going ahead to step 2:
53 divided by 258 is 0 with a remainder of 53.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 53, we end up with 53.
Bring next digit (4) of the dividend behind the 53 and repeat the process: 534 / 258

Let's proceed to step 3:
The number 258 fits into 534 2 times, leaving a remainder of 18.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we take 516 away from 534, we end up with 18.
Take the next digit (0) from the dividend and append it to 18, then repeat: 180 / 258

Going ahead to step 4:
258 can be fit into 180 0 times, resulting in a remainder of 180.
The next digit of our result is 0. 
Result so far: 20.0
Subtracting 0 from 180 leaves us with 180.
Grab the next digit (4) from the dividend, add it to 180, then carry on: 1804 / 258

On to step 5:
When dividing 1804 by 258, we get 6 with a remainder of 256.
Write down 6 as next digit of the result. 
Result so far: 206.0
Deduct 1548 from 1804 and we're left with 256.
Take the next digit (6) from the dividend and append it to 256, then repeat: 2566 / 258

Moving on to step 6:
2566 divided by 258 is 9 with a remainder of 244.
Record the quotient 9 as the next digit in the result. 
Result so far: 2069.0
Deduct 2322 from 2566 and we're left with 244.
Bring next digit (7) of the dividend behind the 244 and repeat the process: 2447 / 258

Advancing to step 7:
The number 258 fits into 2447 9 times, leaving a remainder of 125.
Use 9 as the next digit of our solution. 
Result so far: 20699.0
The remainder is 125 after subtracting 2322 from 2447.
Append the next digit (2) from the dividend to 125 and continue with: 1252 / 258

Step 8:
258 goes into 1252 4 times with a remainder of 220.
The next digit of our result is 4. 
Result so far: 206994.0
Subtract 1032 from 1252 to get 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Step 9:
258 can be fit into 2200 8 times, resulting in a remainder of 136.
The number 8 becomes the next digit in our result. 
Result so far: 206994.8
Deduct 2064 from 2200 and we're left with 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Going ahead to step 10:
If we divide 1360 by 258, we get 5 and a remainder of 70.
Use 5 as the next digit of our solution. 
Result so far: 206994.85
Deduct 1290 from 1360 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 11:
The number 258 fits into 700 2 times, leaving a remainder of 184.
The next digit of our result is 2. 
Result so far: 206994.852
The remainder is 184 after subtracting 516 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Step 12:
258 goes into 1840 7 times with a remainder of 34.
The next digit of our result is 7. 
Result so far: 206994.8527
Deduct 1806 from 1840 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 13:
340 divided by 258 is 1 with a remainder of 82.
Record the quotient 1 as the next digit in the result. 
Result so far: 206994.85271
Subtracting 258 from 340 leaves us with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

On to step 14:
820 divided by 258 is 3 with a remainder of 46.
Use 3 as the next digit of our solution. 
Result so far: 206994.852713
The remainder is 46 after subtracting 774 from 820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Moving on to step 15:
When dividing 460 by 258, we get 1 with a remainder of 202.
Put 1 as the next digit of the answer. 
Result so far: 206994.8527131
The remainder is 202 after subtracting 258 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

Advancing to step 16:
The number 258 fits into 2020 7 times, leaving a remainder of 214.
Put 7 as the next digit of the answer. 
Result so far: 206994.85271317
Subtracting 1806 from 2020 leaves us with 214.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

Our division results in 206994.85271317 with a remaining 2.14e-07.
