Let's divide 89387942 by 978
Our goal is to divide 89387942 by 978.

On to step 1:
8 divided by 978 is 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Grab the next digit (9) from the dividend, add it to 8, then carry on: 89 / 978

Step 2:
89 divided by 978 is 0 with a remainder of 89.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 89 after subtracting 0 from 89.
Take the next digit (3) from the dividend and append it to 89, then repeat: 893 / 978

Moving on to step 3:
The number 978 fits into 893 0 times, leaving a remainder of 893.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 893 leaves us with 893.
Append the next digit (8) from the dividend to 893 and continue with: 8938 / 978

Step 4:
The number 978 fits into 8938 9 times, leaving a remainder of 136.
The next digit of our result is 9. 
Result so far: 9.0
Subtracting 8802 from 8938 leaves us with 136.
Append the next digit (7) from the dividend to 136 and continue with: 1367 / 978

Moving on to step 5:
1367 divided by 978 is 1 with a remainder of 389.
Record the quotient 1 as the next digit in the result. 
Result so far: 91.0
Deduct 978 from 1367 and we're left with 389.
Grab the next digit (9) from the dividend, add it to 389, then carry on: 3899 / 978

Going ahead to step 6:
978 can be fit into 3899 3 times, resulting in a remainder of 965.
The number 3 becomes the next digit in our result. 
Result so far: 913.0
Subtract 2934 from 3899 to get 965.
Fetch the next digit (4) from the dividend, attach it to 965 and continue: 9654 / 978

Advancing to step 7:
9654 divided by 978 is 9 with a remainder of 852.
The next digit of our result is 9. 
Result so far: 9139.0
The remainder is 852 after subtracting 8802 from 9654.
Append the next digit (2) from the dividend to 852 and continue with: 8522 / 978

On to step 8:
The number 978 fits into 8522 8 times, leaving a remainder of 698.
Put 8 as the next digit of the answer. 
Result so far: 91398.0
If we take 7824 away from 8522, we end up with 698.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6980, and continue the process.

Going ahead to step 9:
6980 divided by 978 is 7 with a remainder of 134.
Put 7 as the next digit of the answer. 
Result so far: 91398.7
Subtract 6846 from 6980 to get 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

Advancing to step 10:
978 goes into 1340 1 times with a remainder of 362.
Record the quotient 1 as the next digit in the result. 
Result so far: 91398.71
Subtract 978 from 1340 to get 362.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3620, and continue the process.

Advancing to step 11:
When dividing 3620 by 978, we get 3 with a remainder of 686.
Record the quotient 3 as the next digit in the result. 
Result so far: 91398.713
Subtracting 2934 from 3620 leaves us with 686.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6860, and continue the process.

On to step 12:
The number 978 fits into 6860 7 times, leaving a remainder of 14.
Put 7 as the next digit of the answer. 
Result so far: 91398.7137
If we take 6846 away from 6860, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 13:
The number 978 fits into 140 0 times, leaving a remainder of 140.
Use 0 as the next digit of our solution. 
Result so far: 91398.7137
Deduct 0 from 140 and we're left with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Let's proceed to step 14:
1400 divided by 978 is 1 with a remainder of 422.
Put 1 as the next digit of the answer. 
Result so far: 91398.713701
If we take 978 away from 1400, we end up with 422.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4220, and continue the process.

Step 15:
If we divide 4220 by 978, we get 4 and a remainder of 308.
Use 4 as the next digit of our solution. 
Result so far: 91398.7137014
Subtract 3912 from 4220 to get 308.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

Moving on to step 16:
3080 divided by 978 is 3 with a remainder of 146.
Use 3 as the next digit of our solution. 
Result so far: 91398.71370143
The remainder is 146 after subtracting 2934 from 3080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

After the division, we end up with 91398.71370143 and a remainder of 1.46e-07.
