Going ahead to step 7:
3472 divided by 398 is 8 with a remainder of 288.
Record the quotient 8 as the next digit in the result. 
Result so far: 12598.0
Subtracting 3184 from 3472 leaves us with 288.
Grab the next digit (1) from the dividend, add it to 288, then carry on: 2881 / 398

Moving on to step 8:
398 goes into 2881 7 times with a remainder of 95.
The next digit of our result is 7. 
Result so far: 125987.0
Subtract 2786 from 2881 to get 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Let's proceed to step 9:
398 can be fit into 950 2 times, resulting in a remainder of 154.
Write down 2 as next digit of the result. 
Result so far: 125987.2
Subtracting 796 from 950 leaves us with 154.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

On to step 10:
When dividing 1540 by 398, we get 3 with a remainder of 346.
Use 3 as the next digit of our solution. 
Result so far: 125987.23
Deduct 1194 from 1540 and we're left with 346.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3460, and continue the process.

Going ahead to step 11:
3460 divided by 398 is 8 with a remainder of 276.
Put 8 as the next digit of the answer. 
Result so far: 125987.238
Subtract 3184 from 3460 to get 276.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

Going ahead to step 12:
398 can be fit into 2760 6 times, resulting in a remainder of 372.
Write down 6 as next digit of the result. 
Result so far: 125987.2386
Subtract 2388 from 2760 to get 372.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3720, and continue the process.

Going ahead to step 13:
When dividing 3720 by 398, we get 9 with a remainder of 138.
Put 9 as the next digit of the answer. 
Result so far: 125987.23869
Subtract 3582 from 3720 to get 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

On to step 14:
398 goes into 1380 3 times with a remainder of 186.
The number 3 becomes the next digit in our result. 
Result so far: 125987.238693
If we take 1194 away from 1380, we end up with 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

Going ahead to step 15:
398 goes into 1860 4 times with a remainder of 268.
Put 4 as the next digit of the answer. 
Result so far: 125987.2386934
Deduct 1592 from 1860 and we're left with 268.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

Moving on to step 16:
398 can be fit into 2680 6 times, resulting in a remainder of 292.
The number 6 becomes the next digit in our result. 
Result so far: 125987.23869346
Deduct 2388 from 2680 and we're left with 292.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

The quotient of the division is 125987.23869346, and the remainder is 2.92e-07.
