Let's divide 98874725 by 688
We want to divide 98874725 by 688.

Step 1:
The number 688 fits into 9 0 times, leaving a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Fetch the next digit (8) from the dividend, attach it to 9 and continue: 98 / 688

On to step 2:
98 divided by 688 is 0 with a remainder of 98.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 98 and we're left with 98.
Append the next digit (8) from the dividend to 98 and continue with: 988 / 688

Step 3:
688 goes into 988 1 times with a remainder of 300.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 688 from 988 leaves us with 300.
Append the next digit (7) from the dividend to 300 and continue with: 3007 / 688

On to step 4:
If we divide 3007 by 688, we get 4 and a remainder of 255.
The next digit of our result is 4. 
Result so far: 14.0
Subtract 2752 from 3007 to get 255.
Take the next digit (4) from the dividend and append it to 255, then repeat: 2554 / 688

Step 5:
688 can be fit into 2554 3 times, resulting in a remainder of 490.
Record the quotient 3 as the next digit in the result. 
Result so far: 143.0
Deduct 2064 from 2554 and we're left with 490.
Bring next digit (7) of the dividend behind the 490 and repeat the process: 4907 / 688

Step 6:
When dividing 4907 by 688, we get 7 with a remainder of 91.
Record the quotient 7 as the next digit in the result. 
Result so far: 1437.0
Subtracting 4816 from 4907 leaves us with 91.
Fetch the next digit (2) from the dividend, attach it to 91 and continue: 912 / 688

Going ahead to step 7:
688 goes into 912 1 times with a remainder of 224.
The next digit of our result is 1. 
Result so far: 14371.0
If we subtract 688 from 912, we get 224.
Grab the next digit (5) from the dividend, add it to 224, then carry on: 2245 / 688

Advancing to step 8:
2245 divided by 688 is 3 with a remainder of 181.
Put 3 as the next digit of the answer. 
Result so far: 143713.0
The remainder is 181 after subtracting 2064 from 2245.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1810, and continue the process.

On to step 9:
If we divide 1810 by 688, we get 2 and a remainder of 434.
Use 2 as the next digit of our solution. 
Result so far: 143713.2
The remainder is 434 after subtracting 1376 from 1810.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4340, and continue the process.

Moving on to step 10:
688 can be fit into 4340 6 times, resulting in a remainder of 212.
Write down 6 as next digit of the result. 
Result so far: 143713.26
Subtract 4128 from 4340 to get 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

Moving on to step 11:
If we divide 2120 by 688, we get 3 and a remainder of 56.
Use 3 as the next digit of our solution. 
Result so far: 143713.263
Subtracting 2064 from 2120 leaves us with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Moving on to step 12:
The number 688 fits into 560 0 times, leaving a remainder of 560.
Put 0 as the next digit of the answer. 
Result so far: 143713.263
If we take 0 away from 560, we end up with 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

On to step 13:
5600 divided by 688 is 8 with a remainder of 96.
Put 8 as the next digit of the answer. 
Result so far: 143713.26308
If we take 5504 away from 5600, we end up with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Moving on to step 14:
688 can be fit into 960 1 times, resulting in a remainder of 272.
Write down 1 as next digit of the result. 
Result so far: 143713.263081
If we subtract 688 from 960, we get 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

Advancing to step 15:
When dividing 2720 by 688, we get 3 with a remainder of 656.
Use 3 as the next digit of our solution. 
Result so far: 143713.2630813
If we subtract 2064 from 2720, we get 656.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6560, and continue the process.

Moving on to step 16:
The number 688 fits into 6560 9 times, leaving a remainder of 368.
Put 9 as the next digit of the answer. 
Result so far: 143713.26308139
Subtracting 6192 from 6560 leaves us with 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

After the division, we end up with 143713.26308139 and a remainder of 3.68e-07.
