Let's divide 78646647 by 653
We're looking to find how many times 653 goes into 78646647.

On to step 1:
The number 653 fits into 7 0 times, leaving a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 653

Moving on to step 2:
653 can be fit into 78 0 times, resulting in a remainder of 78.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 78 leaves us with 78.
Bring next digit (6) of the dividend behind the 78 and repeat the process: 786 / 653

Let's proceed to step 3:
If we divide 786 by 653, we get 1 and a remainder of 133.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 653 from 786, we get 133.
Include the next digit (4) from the dividend after 133, then repeat: 1334 / 653

Going ahead to step 4:
1334 divided by 653 is 2 with a remainder of 28.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
The remainder is 28 after subtracting 1306 from 1334.
Include the next digit (6) from the dividend after 28, then repeat: 286 / 653

Advancing to step 5:
653 goes into 286 0 times with a remainder of 286.
The next digit of our result is 0. 
Result so far: 120.0
Subtract 0 from 286 to get 286.
Fetch the next digit (6) from the dividend, attach it to 286 and continue: 2866 / 653

Advancing to step 6:
653 can be fit into 2866 4 times, resulting in a remainder of 254.
The number 4 becomes the next digit in our result. 
Result so far: 1204.0
If we take 2612 away from 2866, we end up with 254.
Grab the next digit (4) from the dividend, add it to 254, then carry on: 2544 / 653

Going ahead to step 7:
2544 divided by 653 is 3 with a remainder of 585.
Put 3 as the next digit of the answer. 
Result so far: 12043.0
If we subtract 1959 from 2544, we get 585.
Fetch the next digit (7) from the dividend, attach it to 585 and continue: 5857 / 653

Going ahead to step 8:
The number 653 fits into 5857 8 times, leaving a remainder of 633.
The next digit of our result is 8. 
Result so far: 120438.0
If we subtract 5224 from 5857, we get 633.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6330, and continue the process.

On to step 9:
6330 divided by 653 is 9 with a remainder of 453.
Put 9 as the next digit of the answer. 
Result so far: 120438.9
Subtract 5877 from 6330 to get 453.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4530, and continue the process.

Moving on to step 10:
The number 653 fits into 4530 6 times, leaving a remainder of 612.
The number 6 becomes the next digit in our result. 
Result so far: 120438.96
If we subtract 3918 from 4530, we get 612.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6120, and continue the process.

Advancing to step 11:
The number 653 fits into 6120 9 times, leaving a remainder of 243.
The number 9 becomes the next digit in our result. 
Result so far: 120438.969
If we subtract 5877 from 6120, we get 243.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2430, and continue the process.

Let's proceed to step 12:
2430 divided by 653 is 3 with a remainder of 471.
Put 3 as the next digit of the answer. 
Result so far: 120438.9693
Subtract 1959 from 2430 to get 471.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4710, and continue the process.

Let's proceed to step 13:
When dividing 4710 by 653, we get 7 with a remainder of 139.
Use 7 as the next digit of our solution. 
Result so far: 120438.96937
Subtract 4571 from 4710 to get 139.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1390, and continue the process.

Going ahead to step 14:
1390 divided by 653 is 2 with a remainder of 84.
The number 2 becomes the next digit in our result. 
Result so far: 120438.969372
Deduct 1306 from 1390 and we're left with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Advancing to step 15:
If we divide 840 by 653, we get 1 and a remainder of 187.
The next digit of our result is 1. 
Result so far: 120438.9693721
Subtract 653 from 840 to get 187.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1870, and continue the process.

On to step 16:
1870 divided by 653 is 2 with a remainder of 564.
Put 2 as the next digit of the answer. 
Result so far: 120438.96937212
If we take 1306 away from 1870, we end up with 564.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5640, and continue the process.

The final result is 120438.96937212 with a remainder of 5.64e-07.
