Let's divide 77445971 by 403
We want to figure out the number of times 77445971 can be divided by 403.

Advancing to step 1:
7 divided by 403 is 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Take the next digit (7) from the dividend and append it to 7, then repeat: 77 / 403

Moving on to step 2:
403 goes into 77 0 times with a remainder of 77.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 77, we get 77.
Grab the next digit (4) from the dividend, add it to 77, then carry on: 774 / 403

Going ahead to step 3:
The number 403 fits into 774 1 times, leaving a remainder of 371.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 403 from 774 leaves us with 371.
Bring next digit (4) of the dividend behind the 371 and repeat the process: 3714 / 403

Moving on to step 4:
403 goes into 3714 9 times with a remainder of 87.
The number 9 becomes the next digit in our result. 
Result so far: 19.0
Subtract 3627 from 3714 to get 87.
Bring next digit (5) of the dividend behind the 87 and repeat the process: 875 / 403

Advancing to step 5:
When dividing 875 by 403, we get 2 with a remainder of 69.
Write down 2 as next digit of the result. 
Result so far: 192.0
If we subtract 806 from 875, we get 69.
Take the next digit (9) from the dividend and append it to 69, then repeat: 699 / 403

Step 6:
699 divided by 403 is 1 with a remainder of 296.
Use 1 as the next digit of our solution. 
Result so far: 1921.0
If we subtract 403 from 699, we get 296.
Include the next digit (7) from the dividend after 296, then repeat: 2967 / 403

Let's proceed to step 7:
403 goes into 2967 7 times with a remainder of 146.
The next digit of our result is 7. 
Result so far: 19217.0
Subtracting 2821 from 2967 leaves us with 146.
Grab the next digit (1) from the dividend, add it to 146, then carry on: 1461 / 403

Moving on to step 8:
1461 divided by 403 is 3 with a remainder of 252.
Write down 3 as next digit of the result. 
Result so far: 192173.0
Subtract 1209 from 1461 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 9:
If we divide 2520 by 403, we get 6 and a remainder of 102.
The next digit of our result is 6. 
Result so far: 192173.6
If we take 2418 away from 2520, we end up with 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

Going ahead to step 10:
The number 403 fits into 1020 2 times, leaving a remainder of 214.
Record the quotient 2 as the next digit in the result. 
Result so far: 192173.62
The remainder is 214 after subtracting 806 from 1020.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

Step 11:
When dividing 2140 by 403, we get 5 with a remainder of 125.
Use 5 as the next digit of our solution. 
Result so far: 192173.625
If we take 2015 away from 2140, we end up with 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

On to step 12:
1250 divided by 403 is 3 with a remainder of 41.
The next digit of our result is 3. 
Result so far: 192173.6253
Subtract 1209 from 1250 to get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Step 13:
403 can be fit into 410 1 times, resulting in a remainder of 7.
Put 1 as the next digit of the answer. 
Result so far: 192173.62531
Deduct 403 from 410 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 14:
70 divided by 403 is 0 with a remainder of 70.
The next digit of our result is 0. 
Result so far: 192173.62531
Deduct 0 from 70 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 15:
When dividing 700 by 403, we get 1 with a remainder of 297.
Record the quotient 1 as the next digit in the result. 
Result so far: 192173.6253101
Subtract 403 from 700 to get 297.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2970, and continue the process.

Going ahead to step 16:
When dividing 2970 by 403, we get 7 with a remainder of 149.
Put 7 as the next digit of the answer. 
Result so far: 192173.62531017
Deduct 2821 from 2970 and we're left with 149.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1490, and continue the process.

The final outcome is 192173.62531017, with a leftover of 1.49e-07.
