We look at the division of 51425531 by 658 
We want to divide 51425531 by 658.

Going ahead to step 1:
5 divided by 658 is 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 658

Step 2:
The number 658 fits into 51 0 times, leaving a remainder of 51.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 51 after subtracting 0 from 51.
Fetch the next digit (4) from the dividend, attach it to 51 and continue: 514 / 658

Moving on to step 3:
When dividing 514 by 658, we get 0 with a remainder of 514.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 514 leaves us with 514.
Include the next digit (2) from the dividend after 514, then repeat: 5142 / 658

Step 4:
The number 658 fits into 5142 7 times, leaving a remainder of 536.
Use 7 as the next digit of our solution. 
Result so far: 7.0
If we subtract 4606 from 5142, we get 536.
Grab the next digit (5) from the dividend, add it to 536, then carry on: 5365 / 658

Advancing to step 5:
658 can be fit into 5365 8 times, resulting in a remainder of 101.
Write down 8 as next digit of the result. 
Result so far: 78.0
Deduct 5264 from 5365 and we're left with 101.
Fetch the next digit (5) from the dividend, attach it to 101 and continue: 1015 / 658

Moving on to step 6:
658 goes into 1015 1 times with a remainder of 357.
The number 1 becomes the next digit in our result. 
Result so far: 781.0
If we take 658 away from 1015, we end up with 357.
Append the next digit (3) from the dividend to 357 and continue with: 3573 / 658

Step 7:
658 can be fit into 3573 5 times, resulting in a remainder of 283.
Use 5 as the next digit of our solution. 
Result so far: 7815.0
If we subtract 3290 from 3573, we get 283.
Take the next digit (1) from the dividend and append it to 283, then repeat: 2831 / 658

Advancing to step 8:
658 goes into 2831 4 times with a remainder of 199.
The next digit of our result is 4. 
Result so far: 78154.0
The remainder is 199 after subtracting 2632 from 2831.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1990, and continue the process.

Going ahead to step 9:
658 can be fit into 1990 3 times, resulting in a remainder of 16.
The number 3 becomes the next digit in our result. 
Result so far: 78154.3
The remainder is 16 after subtracting 1974 from 1990.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 10:
When dividing 160 by 658, we get 0 with a remainder of 160.
Record the quotient 0 as the next digit in the result. 
Result so far: 78154.3
If we take 0 away from 160, we end up with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Moving on to step 11:
If we divide 1600 by 658, we get 2 and a remainder of 284.
Put 2 as the next digit of the answer. 
Result so far: 78154.302
If we take 1316 away from 1600, 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.

Let's proceed to step 12:
If we divide 2840 by 658, we get 4 and a remainder of 208.
Use 4 as the next digit of our solution. 
Result so far: 78154.3024
If we subtract 2632 from 2840, we get 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Let's proceed to step 13:
When dividing 2080 by 658, we get 3 with a remainder of 106.
The number 3 becomes the next digit in our result. 
Result so far: 78154.30243
If we take 1974 away from 2080, we end up with 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Step 14:
When dividing 1060 by 658, we get 1 with a remainder of 402.
Record the quotient 1 as the next digit in the result. 
Result so far: 78154.302431
Deduct 658 from 1060 and we're left with 402.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4020, and continue the process.

Moving on to step 15:
4020 divided by 658 is 6 with a remainder of 72.
Record the quotient 6 as the next digit in the result. 
Result so far: 78154.3024316
If we take 3948 away from 4020, we end up with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Step 16:
720 divided by 658 is 1 with a remainder of 62.
Put 1 as the next digit of the answer. 
Result so far: 78154.30243161
Deduct 658 from 720 and we're left with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

The quotient of the division is 78154.30243161, and the remainder is 6.2e-08.
