We look at the division of 51946962 by 419 
We want to divide 51946962 by 419.

Step 1:
5 divided by 419 is 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 419

On to step 2:
419 goes into 51 0 times with a remainder of 51.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 51 and we're left with 51.
Append the next digit (9) from the dividend to 51 and continue with: 519 / 419

Moving on to step 3:
519 divided by 419 is 1 with a remainder of 100.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 419 from 519, we get 100.
Bring next digit (4) of the dividend behind the 100 and repeat the process: 1004 / 419

On to step 4:
If we divide 1004 by 419, we get 2 and a remainder of 166.
Use 2 as the next digit of our solution. 
Result so far: 12.0
If we subtract 838 from 1004, we get 166.
Bring next digit (6) of the dividend behind the 166 and repeat the process: 1666 / 419

Moving on to step 5:
When dividing 1666 by 419, we get 3 with a remainder of 409.
Record the quotient 3 as the next digit in the result. 
Result so far: 123.0
The remainder is 409 after subtracting 1257 from 1666.
Grab the next digit (9) from the dividend, add it to 409, then carry on: 4099 / 419

Let's proceed to step 6:
The number 419 fits into 4099 9 times, leaving a remainder of 328.
The number 9 becomes the next digit in our result. 
Result so far: 1239.0
Deduct 3771 from 4099 and we're left with 328.
Append the next digit (6) from the dividend to 328 and continue with: 3286 / 419

Going ahead to step 7:
When dividing 3286 by 419, we get 7 with a remainder of 353.
Write down 7 as next digit of the result. 
Result so far: 12397.0
Subtract 2933 from 3286 to get 353.
Append the next digit (2) from the dividend to 353 and continue with: 3532 / 419

Moving on to step 8:
When dividing 3532 by 419, we get 8 with a remainder of 180.
Use 8 as the next digit of our solution. 
Result so far: 123978.0
Subtracting 3352 from 3532 leaves us with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Advancing to step 9:
When dividing 1800 by 419, we get 4 with a remainder of 124.
The number 4 becomes the next digit in our result. 
Result so far: 123978.4
Subtract 1676 from 1800 to get 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

Advancing to step 10:
If we divide 1240 by 419, we get 2 and a remainder of 402.
Write down 2 as next digit of the result. 
Result so far: 123978.42
If we subtract 838 from 1240, we get 402.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4020, and continue the process.

Step 11:
When dividing 4020 by 419, we get 9 with a remainder of 249.
Write down 9 as next digit of the result. 
Result so far: 123978.429
Subtract 3771 from 4020 to get 249.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2490, and continue the process.

Step 12:
When dividing 2490 by 419, we get 5 with a remainder of 395.
The number 5 becomes the next digit in our result. 
Result so far: 123978.4295
If we subtract 2095 from 2490, we get 395.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3950, and continue the process.

Let's proceed to step 13:
When dividing 3950 by 419, we get 9 with a remainder of 179.
Record the quotient 9 as the next digit in the result. 
Result so far: 123978.42959
If we take 3771 away from 3950, we end up with 179.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1790, and continue the process.

Going ahead to step 14:
419 goes into 1790 4 times with a remainder of 114.
Put 4 as the next digit of the answer. 
Result so far: 123978.429594
The remainder is 114 after subtracting 1676 from 1790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

Advancing to step 15:
419 goes into 1140 2 times with a remainder of 302.
Write down 2 as next digit of the result. 
Result so far: 123978.4295942
Deduct 838 from 1140 and we're left with 302.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3020, and continue the process.

On to step 16:
The number 419 fits into 3020 7 times, leaving a remainder of 87.
Write down 7 as next digit of the result. 
Result so far: 123978.42959427
Deduct 2933 from 3020 and we're left with 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

After the division, we end up with 123978.42959427 and a remainder of 8.7e-08.
