Subtracting 0 from 7 leaves us with 7.
Append the next digit (3) from the dividend to 7 and continue with: 73 / 76

Advancing to step 2:
73 divided by 76 is 0 with a remainder of 73.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 73 and we're left with 73.
Take the next digit (9) from the dividend and append it to 73, then repeat: 739 / 76

Moving on to step 3:
If we divide 739 by 76, we get 9 and a remainder of 55.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Deduct 684 from 739 and we're left with 55.
Append the next digit (1) from the dividend to 55 and continue with: 551 / 76

Moving on to step 4:
76 goes into 551 7 times with a remainder of 19.
Write down 7 as next digit of the result. 
Result so far: 97.0
Deduct 532 from 551 and we're left with 19.
Grab the next digit (9) from the dividend, add it to 19, then carry on: 199 / 76

Let's proceed to step 5:
76 goes into 199 2 times with a remainder of 47.
Write down 2 as next digit of the result. 
Result so far: 972.0
Subtract 152 from 199 to get 47.
Grab the next digit (6) from the dividend, add it to 47, then carry on: 476 / 76

On to step 6:
If we divide 476 by 76, we get 6 and a remainder of 20.
Record the quotient 6 as the next digit in the result. 
Result so far: 9726.0
Subtract 456 from 476 to get 20.
Include the next digit (2) from the dividend after 20, then repeat: 202 / 76

Moving on to step 7:
If we divide 202 by 76, we get 2 and a remainder of 50.
The number 2 becomes the next digit in our result. 
Result so far: 97262.0
Subtract 152 from 202 to get 50.
Fetch the next digit (3) from the dividend, attach it to 50 and continue: 503 / 76

Advancing to step 8:
76 goes into 503 6 times with a remainder of 47.
Use 6 as the next digit of our solution. 
Result so far: 972626.0
The remainder is 47 after subtracting 456 from 503.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

On to step 9:
76 can be fit into 470 6 times, resulting in a remainder of 14.
The number 6 becomes the next digit in our result. 
Result so far: 972626.6
The remainder is 14 after subtracting 456 from 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 10:
76 can be fit into 140 1 times, resulting in a remainder of 64.
The next digit of our result is 1. 
Result so far: 972626.61
Deduct 76 from 140 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 11:
The number 76 fits into 640 8 times, leaving a remainder of 32.
Put 8 as the next digit of the answer. 
Result so far: 972626.618
The remainder is 32 after subtracting 608 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 12:
When dividing 320 by 76, we get 4 with a remainder of 16.
Use 4 as the next digit of our solution. 
Result so far: 972626.6184
Deduct 304 from 320 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 13:
The number 76 fits into 160 2 times, leaving a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 972626.61842
Subtracting 152 from 160 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 14:
The number 76 fits into 80 1 times, leaving a remainder of 4.
The number 1 becomes the next digit in our result. 
Result so far: 972626.618421
Deduct 76 from 80 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 15:
If we divide 40 by 76, we get 0 and a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 972626.618421
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 16:
400 divided by 76 is 5 with a remainder of 20.
Use 5 as the next digit of our solution. 
Result so far: 972626.61842105
The remainder is 20 after subtracting 380 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

After the division, we end up with 972626.61842105 and a remainder of 2e-08.
