We look at the division of 51597628 by 451 
We want to divide 51597628 by 451.

Let's proceed to step 1:
If we divide 5 by 451, we get 0 and a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Append the next digit (1) from the dividend to 5 and continue with: 51 / 451

Step 2:
If we divide 51 by 451, we get 0 and a remainder of 51.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 51 to get 51.
Bring next digit (5) of the dividend behind the 51 and repeat the process: 515 / 451

Advancing to step 3:
515 divided by 451 is 1 with a remainder of 64.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 451 from 515 leaves us with 64.
Include the next digit (9) from the dividend after 64, then repeat: 649 / 451

Advancing to step 4:
451 can be fit into 649 1 times, resulting in a remainder of 198.
The next digit of our result is 1. 
Result so far: 11.0
Deduct 451 from 649 and we're left with 198.
Append the next digit (7) from the dividend to 198 and continue with: 1987 / 451

Advancing to step 5:
When dividing 1987 by 451, we get 4 with a remainder of 183.
The number 4 becomes the next digit in our result. 
Result so far: 114.0
If we take 1804 away from 1987, we end up with 183.
Take the next digit (6) from the dividend and append it to 183, then repeat: 1836 / 451

Let's proceed to step 6:
451 goes into 1836 4 times with a remainder of 32.
The next digit of our result is 4. 
Result so far: 1144.0
Deduct 1804 from 1836 and we're left with 32.
Bring next digit (2) of the dividend behind the 32 and repeat the process: 322 / 451

Let's proceed to step 7:
451 goes into 322 0 times with a remainder of 322.
Use 0 as the next digit of our solution. 
Result so far: 11440.0
Subtracting 0 from 322 leaves us with 322.
Grab the next digit (8) from the dividend, add it to 322, then carry on: 3228 / 451

Advancing to step 8:
When dividing 3228 by 451, we get 7 with a remainder of 71.
Write down 7 as next digit of the result. 
Result so far: 114407.0
Deduct 3157 from 3228 and we're left with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

On to step 9:
When dividing 710 by 451, we get 1 with a remainder of 259.
Put 1 as the next digit of the answer. 
Result so far: 114407.1
If we subtract 451 from 710, we get 259.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2590, and continue the process.

Advancing to step 10:
2590 divided by 451 is 5 with a remainder of 335.
Put 5 as the next digit of the answer. 
Result so far: 114407.15
Deduct 2255 from 2590 and we're left with 335.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3350, and continue the process.

Moving on to step 11:
451 goes into 3350 7 times with a remainder of 193.
The next digit of our result is 7. 
Result so far: 114407.157
Deduct 3157 from 3350 and we're left with 193.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1930, and continue the process.

Going ahead to step 12:
When dividing 1930 by 451, we get 4 with a remainder of 126.
The number 4 becomes the next digit in our result. 
Result so far: 114407.1574
The remainder is 126 after subtracting 1804 from 1930.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Moving on to step 13:
If we divide 1260 by 451, we get 2 and a remainder of 358.
The number 2 becomes the next digit in our result. 
Result so far: 114407.15742
If we take 902 away from 1260, we end up with 358.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3580, and continue the process.

Advancing to step 14:
451 goes into 3580 7 times with a remainder of 423.
Use 7 as the next digit of our solution. 
Result so far: 114407.157427
Deduct 3157 from 3580 and we're left with 423.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4230, and continue the process.

Advancing to step 15:
451 can be fit into 4230 9 times, resulting in a remainder of 171.
Use 9 as the next digit of our solution. 
Result so far: 114407.1574279
Deduct 4059 from 4230 and we're left with 171.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1710, and continue the process.

Step 16:
451 goes into 1710 3 times with a remainder of 357.
Record the quotient 3 as the next digit in the result. 
Result so far: 114407.15742793
Subtract 1353 from 1710 to get 357.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3570, and continue the process.

After the division, we end up with 114407.15742793 and a remainder of 3.57e-07.
