Grab the next digit (7) from the dividend, add it to 212, then carry on: 2127 / 667

Advancing to step 4:
If we divide 2127 by 667, we get 3 and a remainder of 126.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtracting 2001 from 2127 leaves us with 126.
Append the next digit (6) from the dividend to 126 and continue with: 1266 / 667

Moving on to step 5:
When dividing 1266 by 667, we get 1 with a remainder of 599.
Put 1 as the next digit of the answer. 
Result so far: 31.0
If we take 667 away from 1266, we end up with 599.
Take the next digit (5) from the dividend and append it to 599, then repeat: 5995 / 667

Advancing to step 6:
667 goes into 5995 8 times with a remainder of 659.
Put 8 as the next digit of the answer. 
Result so far: 318.0
The remainder is 659 after subtracting 5336 from 5995.
Take the next digit (3) from the dividend and append it to 659, then repeat: 6593 / 667

Advancing to step 7:
When dividing 6593 by 667, we get 9 with a remainder of 590.
Put 9 as the next digit of the answer. 
Result so far: 3189.0
Subtract 6003 from 6593 to get 590.
Fetch the next digit (8) from the dividend, attach it to 590 and continue: 5908 / 667

Moving on to step 8:
5908 divided by 667 is 8 with a remainder of 572.
The next digit of our result is 8. 
Result so far: 31898.0
If we subtract 5336 from 5908, we get 572.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5720, and continue the process.

Advancing to step 9:
If we divide 5720 by 667, we get 8 and a remainder of 384.
The next digit of our result is 8. 
Result so far: 31898.8
Subtract 5336 from 5720 to get 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Advancing to step 10:
When dividing 3840 by 667, we get 5 with a remainder of 505.
Write down 5 as next digit of the result. 
Result so far: 31898.85
Subtract 3335 from 3840 to get 505.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5050, and continue the process.

Let's proceed to step 11:
If we divide 5050 by 667, we get 7 and a remainder of 381.
Use 7 as the next digit of our solution. 
Result so far: 31898.857
If we subtract 4669 from 5050, we get 381.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3810, and continue the process.

Let's proceed to step 12:
667 goes into 3810 5 times with a remainder of 475.
The number 5 becomes the next digit in our result. 
Result so far: 31898.8575
If we take 3335 away from 3810, we end up with 475.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4750, and continue the process.

Moving on to step 13:
If we divide 4750 by 667, we get 7 and a remainder of 81.
Use 7 as the next digit of our solution. 
Result so far: 31898.85757
The remainder is 81 after subtracting 4669 from 4750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Going ahead to step 14:
If we divide 810 by 667, we get 1 and a remainder of 143.
The next digit of our result is 1. 
Result so far: 31898.857571
If we subtract 667 from 810, we get 143.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1430, and continue the process.

Let's proceed to step 15:
When dividing 1430 by 667, we get 2 with a remainder of 96.
Put 2 as the next digit of the answer. 
Result so far: 31898.8575712
The remainder is 96 after subtracting 1334 from 1430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Advancing to step 16:
If we divide 960 by 667, we get 1 and a remainder of 293.
Use 1 as the next digit of our solution. 
Result so far: 31898.85757121
The remainder is 293 after subtracting 667 from 960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2930, and continue the process.

After the division, we end up with 31898.85757121 and a remainder of 2.93e-07.
