We divide 78977320 by 454
We want to figure out the number of times 78977320 can be divided by 454.

Step 1:
7 divided by 454 is 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 454

Step 2:
The number 454 fits into 78 0 times, leaving a remainder of 78.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 78, we end up with 78.
Grab the next digit (9) from the dividend, add it to 78, then carry on: 789 / 454

Going ahead to step 3:
454 can be fit into 789 1 times, resulting in a remainder of 335.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 454 from 789 leaves us with 335.
Append the next digit (7) from the dividend to 335 and continue with: 3357 / 454

Going ahead to step 4:
The number 454 fits into 3357 7 times, leaving a remainder of 179.
Put 7 as the next digit of the answer. 
Result so far: 17.0
Deduct 3178 from 3357 and we're left with 179.
Fetch the next digit (7) from the dividend, attach it to 179 and continue: 1797 / 454

Advancing to step 5:
1797 divided by 454 is 3 with a remainder of 435.
Use 3 as the next digit of our solution. 
Result so far: 173.0
Deduct 1362 from 1797 and we're left with 435.
Append the next digit (3) from the dividend to 435 and continue with: 4353 / 454

On to step 6:
454 goes into 4353 9 times with a remainder of 267.
The number 9 becomes the next digit in our result. 
Result so far: 1739.0
Subtract 4086 from 4353 to get 267.
Grab the next digit (2) from the dividend, add it to 267, then carry on: 2672 / 454

On to step 7:
If we divide 2672 by 454, we get 5 and a remainder of 402.
Use 5 as the next digit of our solution. 
Result so far: 17395.0
Deduct 2270 from 2672 and we're left with 402.
Fetch the next digit (0) from the dividend, attach it to 402 and continue: 4020 / 454

Step 8:
The number 454 fits into 4020 8 times, leaving a remainder of 388.
Put 8 as the next digit of the answer. 
Result so far: 173958.0
Subtract 3632 from 4020 to get 388.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3880, and continue the process.

Advancing to step 9:
454 goes into 3880 8 times with a remainder of 248.
Use 8 as the next digit of our solution. 
Result so far: 173958.8
Deduct 3632 from 3880 and we're left with 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Step 10:
When dividing 2480 by 454, we get 5 with a remainder of 210.
The next digit of our result is 5. 
Result so far: 173958.85
If we take 2270 away from 2480, we end up with 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Step 11:
2100 divided by 454 is 4 with a remainder of 284.
Use 4 as the next digit of our solution. 
Result so far: 173958.854
If we take 1816 away from 2100, 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.

Step 12:
If we divide 2840 by 454, we get 6 and a remainder of 116.
Put 6 as the next digit of the answer. 
Result so far: 173958.8546
Deduct 2724 from 2840 and we're left with 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Going ahead to step 13:
454 can be fit into 1160 2 times, resulting in a remainder of 252.
Use 2 as the next digit of our solution. 
Result so far: 173958.85462
Subtract 908 from 1160 to get 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

Advancing to step 14:
2520 divided by 454 is 5 with a remainder of 250.
Put 5 as the next digit of the answer. 
Result so far: 173958.854625
The remainder is 250 after subtracting 2270 from 2520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Step 15:
454 goes into 2500 5 times with a remainder of 230.
The number 5 becomes the next digit in our result. 
Result so far: 173958.8546255
Deduct 2270 from 2500 and we're left with 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

The final result is 173958.8546255 with a remainder of 2.3e-06.
