We look at the division of 79774561 by 451 
We're looking to find how many times 451 goes into 79774561.

Step 1:
451 can be fit into 7 0 times, resulting in a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Grab the next digit (9) from the dividend, add it to 7, then carry on: 79 / 451

Let's proceed to step 2:
451 can be fit into 79 0 times, resulting in a remainder of 79.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 79 to get 79.
Append the next digit (7) from the dividend to 79 and continue with: 797 / 451

Advancing to step 3:
451 goes into 797 1 times with a remainder of 346.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 346 after subtracting 451 from 797.
Include the next digit (7) from the dividend after 346, then repeat: 3467 / 451

Advancing to step 4:
451 goes into 3467 7 times with a remainder of 310.
Use 7 as the next digit of our solution. 
Result so far: 17.0
If we take 3157 away from 3467, we end up with 310.
Bring next digit (4) of the dividend behind the 310 and repeat the process: 3104 / 451

Let's proceed to step 5:
If we divide 3104 by 451, we get 6 and a remainder of 398.
Use 6 as the next digit of our solution. 
Result so far: 176.0
If we subtract 2706 from 3104, we get 398.
Include the next digit (5) from the dividend after 398, then repeat: 3985 / 451

Let's proceed to step 6:
The number 451 fits into 3985 8 times, leaving a remainder of 377.
Use 8 as the next digit of our solution. 
Result so far: 1768.0
Subtract 3608 from 3985 to get 377.
Fetch the next digit (6) from the dividend, attach it to 377 and continue: 3776 / 451

Advancing to step 7:
If we divide 3776 by 451, we get 8 and a remainder of 168.
Put 8 as the next digit of the answer. 
Result so far: 17688.0
Deduct 3608 from 3776 and we're left with 168.
Grab the next digit (1) from the dividend, add it to 168, then carry on: 1681 / 451

On to step 8:
When dividing 1681 by 451, we get 3 with a remainder of 328.
The number 3 becomes the next digit in our result. 
Result so far: 176883.0
If we subtract 1353 from 1681, we get 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

Step 9:
451 can be fit into 3280 7 times, resulting in a remainder of 123.
The number 7 becomes the next digit in our result. 
Result so far: 176883.7
The remainder is 123 after subtracting 3157 from 3280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1230, and continue the process.

Moving on to step 10:
When dividing 1230 by 451, we get 2 with a remainder of 328.
The next digit of our result is 2. 
Result so far: 176883.72
If we subtract 902 from 1230, we get 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

Moving on to step 11:
451 can be fit into 3280 7 times, resulting in a remainder of 123.
Write down 7 as next digit of the result. 
Result so far: 176883.727
If we take 3157 away from 3280, we end up with 123.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1230, and continue the process.

Step 12:
451 can be fit into 1230 2 times, resulting in a remainder of 328.
Put 2 as the next digit of the answer. 
Result so far: 176883.7272
If we take 902 away from 1230, we end up with 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

On to step 13:
If we divide 3280 by 451, we get 7 and a remainder of 123.
Record the quotient 7 as the next digit in the result. 
Result so far: 176883.72727
Deduct 3157 from 3280 and we're left with 123.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1230, and continue the process.

Going ahead to step 14:
If we divide 1230 by 451, we get 2 and a remainder of 328.
Use 2 as the next digit of our solution. 
Result so far: 176883.727272
Deduct 902 from 1230 and we're left with 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

Moving on to step 15:
451 can be fit into 3280 7 times, resulting in a remainder of 123.
Use 7 as the next digit of our solution. 
Result so far: 176883.7272727
The remainder is 123 after subtracting 3157 from 3280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1230, and continue the process.

On to step 16:
When dividing 1230 by 451, we get 2 with a remainder of 328.
The next digit of our result is 2. 
Result so far: 176883.72727272
If we subtract 902 from 1230, we get 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

The final result is 176883.72727272 with a remainder of 3.28e-07.
